Film / Back to the Future Part II

All spoilers for Back to the Future are unmarked. You Have Been Warned.

Getting back was only the beginning.

Marty McFly: You're not gonna believe this, we gotta go back to 1955!
Doc Brown: I don't believe it!

Back to the Future Part II is a 1989 film directed by Robert Zemeckis, starring Michael J. Fox and Christopher Lloyd. It is the second part of the Back to the Future trilogy.

Picking up from the first movie, Doc Brown takes Marty and his girlfriend Jennifer to 2015 in an attempt to save his identical son from trouble. While successful in their plan, a series of complications involving a sports almanac from the future leads to the elderly Biff Tannen stealing their DeLorean and making his young self rich, altering the present (i.e., 1985) into a dystopia where he is an all-powerful billionaire. Now Marty and Doc have to return to the 1955 school dance from the first movie and Set Right What Once Went Wrong, whilst remaining unseen lest he cause a Time Paradox. But fixing the time-stream and getting home won't be easy...

The film was shot back-to-back with its sequel, Back to the Future Part III, which was released the following year.

Back to the Future Part II provides examples of:

Tropes A-E

• Accidental Time Travel: While the DeLorean is capable of Casual Time Travel (thanks to Mr. Fusion allowing garbage to substitute the plutonium), at the end Doc is flying it during a thunderstorm and gets struck, violently sending him back to 1885.
• Acoustic License: Marty is hiding in the back of Biff's car while Biff is driving. Marty is talking to the Doc on a walkie-talkie. At first, it seems to be an example of this trope when you wonder how could Biff not hear him, he is talking so loudly. However, it turns out to be an aversion — we are hearing from Marty's point of view, but the car is an open top convertible and Biff would have the wind in his ears.
• Actor Allusion:
  • Doc sees a taxi cab in his rearview visor. Is the driver Reverend Jim?
  • Not the first time Doc's been committed.
• Actually Pretty Funny: When 2015 Biff goes back to 1955 and witnesses his past self arguing with Terry, the mechanic, about the repairs to his car, Old Biff chuckles to himself, "The manure! I remember that!" with a nostalgic smile.
• Alien Space Bats: 1985-A. Not only did Biff change the history of Hill Valley for the worse, he also changed world history by helping Richard Nixon remain president for more than a decade, making the The Vietnam War last longer. (An impressive feat given that the presidency was capped at two terms in 1951...)
• All Bikers are Hells Angels: Hill Valley's alternate timeline of "Hell Valley" is partly characterized as a Crapsack World by its infestation with outlaw bikers and trigger-happy gangs.
• Alliterative List: "The pitfalls, the possibilities, the perils, and the promise..."
• All There in the Manual:
  • When elderly 2015 Biff comes back from 1955, he's shown bending over in pain. The rest of the scene, which was edited out, has him disappearing. Word of God invokedsays that Lorraine shot and killed him in the mid 1990's.
  • The reason our real life 2015 doesn't have Mr. Fusion, Self-Lacing Sneakers and Hoverboards, according to the 30th anniversary boxed set, is that the items would have brought on an apocalypse in 2045, so Doc removed them from the time stream.
  • The IDW comic Biff to the Future explains how A-1985 became so chaotic. A day after the school dance, Grandma Tannen forced Biff to drive her to Las Vegas, where he runs afoul of a hustler who tried to rob and kill him, and on his 21st birthday he uses the "Gray's Sports Almanac" to win his first million dollars. He then goes to Hollywood to become a film producer, where his crooked business partner scams him out of a sizable amount of money. After a chance encounter with Ronald Reagan, who decided to go into politics, Biff has his business partner killed and quits show business for good to go into politics himself. Back in Hill Valley, Biff buys his way into the city council and eventually becomes mayor, and has George killed to stop the resistance movement against him. After Biff uses his vast fortune to buy the Washington Post, which owned Hill Valley's local newspaper, Biff accidentally stops the exposé of the Watergate Scandal, which attracts the attention of Richard Nixon. Since no one wanted to take a bet from Biff, or his friends, since the "Gray's Sports Almanac" gave him an edge, Nixon makes Biff an offer: use his vast fortune to help dispose of toxic waste and bribe legislators to repeal the 22nd Amendment, and Nixon will legalize gambling, allowing Biff to open his own casino where he uses "Grey's Sports Almanac" to stack the odds in his favor and keep making winning bets. Doc Brown gets committed to an insane asylum after he and the remnants of the anti-Biff resistance movement get discovered after they keep using the Doc's refrigerator time machine to change the past, which drained the town's power supply.
• All There in the Script: The cops who pick up Jennifer have names — Reese and Foley, the same names Robert Zemeckis and Bob Gale give to all pairs of cops who appear in their films.
• Alternate Timeline: 1985-A's one of the defining examples in cinema (if not modern pop culture). This also is used as a major plot point to justify why Doc and Marty can't simply go back to 2015 and stop Old Biff from stealing the DeLorean. When Marty pitches this very idea, Doc grimly explains traveling forward in time will do no good because the timeline's already been changed; they'd only be traveling into the future of this alternate reality. Their only hope and course of action is instead to discover where and when 1985-A diverged from the original timeline and repair the damage there at its source.
• Ambiguous Syntax: Played for Laughs: When the two female cops take 1985 Jennifer to her 2015 home, they tell her, "And be careful in the future." What they meant, of course, was "Be careful from now on", but Jennifer, who just woke up and is coming to terms with the fact that she traveled through time, took it literally, as in, "Be careful in this future world we live in."
• And Another Thing...: Old Biff to 1955 Biff: "There's one more thing. One day, a kid or a crazy old man who claims to be a scientist is going to come around asking...". This is a callback to an earlier point in the film (though it occurs later chronologically), when 1985A Biff says to Marty: "Oh, and he told me one more thing. He said, 'Someday a crazy, wild-eyed scientist, or a kid may show up asking about that book. 'And if that ever happens...' (pulls out a gun) Funny. I never thought it would be you."
• ...And 99¢: The movie features automobile hover-conversions, "only thirty-nine, nine ninety-nine, ninety-five!" ($39,999.95)
• And This Is for...: Biff says "And this one's for my car!" when kicking Marty.
• And Your Little Dog, Too!: Biff-A to Lorraine-A, in 1985-A, threatens to put Dave, Linda, and Marty in jail if she walks away from him, just like jailbird Joey (who apparently is the one person in the timeline that hasn't changed).
• Apocalypse How: Several potential paradoxes in this film could destroy the entire universe, which would be a Class X-4, worst-scenario. (The effect might actually be localized to their own galaxy, which is a Class X-3.) Then again it could be a Red Herring, as several characters do meet their past/future selves and the worst that happened was that they both passed out from shock. Doc is also unaware that Marty has already seen his past self (albeit only from a week prior) without any damage to the universe, or even the galaxy!
• The Apunkalypse: Not directly employed, but the inspiration behind Griff's gang in the future.
• Artificial Outdoors Display: In 2015, the McFly home has a window with a view of a pleasant sunny meadow. It turns out that the view is artificial ^note It is a TV channel called "The Scenery Channel", and is projected onto a blind which is pulled down over the real glass window in order to hide the view of the urban sprawl.
• Artistic License – History: The game Wild Gunman was released in October 1985 (around the time the film takes place) as a launch title for the Nintendo Entertainment System. However, the NES and its launch games initially only released in the New York City area; the console and games didn't see nationwide launch until mid-1986. Media, both news outlets and gaming publications, didn't start regularly covering Nintendo until well into 1986 so the game would have been largely unknown then. Even the arcade version of Wild Gunman (as noted below) didn't reach American arcades until 1986 and later. Of course, Marty may have known someone who had an import version of the game or acquired the NES Wild Gunman from a New York retailer.
• Ascended Extra: Biff's 1955 gang plays a bigger part. In 1985-A, we see they're still with Biff, and in 1955, they chase Marty into the gym while his other self in the original movie is playing. Because they mistake that Marty for this film's Marty, he has to stop them from attacking his earlier self.
• Ascended Fridge Horror: If you look carefully at the USA Today issue, you see a reference to the "Thumb Bandit". Recall that people make transactions with their thumbprints. A criminal who steals people's identity by chopping off their thumbs? The movie's director confirms that this is, in fact, the case.
• As Long as It Sounds Foreign: 2015 Marty works for a "Mr. Fujitsu"; "Fujitsu" is the name of a Japanese company, but it's short for "Fuji Telecommunications Equipment Manufacturing"^note (Fuji Tsuushinki Seizou if you're wondering, but parsed down to Fuji-Tsuu Kabushiki-gaisha(Stock Company) nowadays), not a surname. Bob Gale remarks on this screw-up in the DVD commentary, and says that it would be like calling somebody "Mr. General Motors."
• As You Know:
  • Played with cleverly; Griff's gang drops a piece of exposition as something they expected Marty Jr. to know, but young Marty Sr. doesn't.
    Data: Hey McFly, you bojo! Those boards don't work on water!
    Whitey: Unless you got POWAH!
  • Later on in the movie, when Marty discovers that the 1985 timeline has been altered, it's revealed that Biff-A has become insanely rich through the almanac 2015 Biff gave him, and furthermore, he has married Lorraine after murdering George McFly. Marty asks Lorraine-A where George is, and she excuses his behavior by sadly saying, "they must have hit you over the head hard this time", which implies that he should know where George is. She answers anyway that he's dead.
• Ax-Crazy:
  • Griff's got "a few short circuits in his bionic implants", which apparently ties in with how, more than any of the Biffs running around, he comes across as downright psycho.
  • Biff in the 1955 segment looks positively gleeful about running "Calvin Klein" over.
• Awful Wedded Life : Imagine being in Lorraine-A's shoes: your husband is murdered and they never find the killer. Then (possibly against your will) you marry the last person on earth you would ever marry.
• Back to the Early Installment: After the 2015 Biff Tannen steals the Gray's Sports Almanac and goes back in time, Doc and Marty have to go back in time to get it back and avert the Bad Future it created. They travel to the events of the first movie since that's when Old Biff wanted to give his younger self the almanac, with their secondary concern being avoiding meeting themselves and interfering with the events of the first movie.
• Bad Liar: After Fujitsu reveals that he was monitoring the illegal transaction, Marty makes the pathetic excuse that he was setting up a sting operation to trap Needles. Fujitsu isn't fooled in the least, firing Marty.
• Bad Future: The filmmakers aimed to avert this trope regarding year 2015, as they didn't want to just rip off Blade Runner and wanted to get people out of that sort-of grim mindset, so they portrayed the future as a generally nice place to live, though not perfect, and that any trouble was caused by the people (like Griff) there, not technology. Also, they knew that whatever they showed would likely become badly dated or inaccurate as the real 2015 came around, so they just made it all into jokes.
• Bad Present: 1985-A. Hill Valley became a post-apocalyptic nightmare. The newspaper announcing Doc Brown's commitment to an insane asylum also announced President Richard Nixon's candidacy for a fifth term despite the Constitutional limit, and Nixon's vow to end the Vietnam War by 1985. The situation is so bad that Doc Brown says that hell couldn't be much worse.
• Bait-and-Switch: Moments after Doc and the DeLorean have disappeared after being struck by lightning, a car pulls up and a sinister looking man in a black suit gets out, walks towards Marty, demands that he confirm his identity and menacingly reaches into his overcoat to produce... a letter. Turns out the guy works for Western Union, and there's been a package waiting for Marty for quite a while...
• Balls of Steel: There is a clang when Marty punches Griff in the groin. Subverted in that he feels the blow.
• Bathtub Scene: Marty interrupts Biff with two Buxom Blondes while they are watching A Fistful of Dollars in a hot tub, to ask about Gray's Sports Almanac.
• Batter Up!:
  • A self-telescoping baseball bat is Griff Tannen's weapon of choice. He even says the trope name before attacking Marty with it.
  • When Marty returns to his house in the 1985-A, he discovers that it is now occupied by a new family. The father of said family is not afraid to use a baseball bat to protect his daughter, who is living in what was once Marty's room.
• Berserk Button: Marty's aversion to being called "chicken" or otherwise having his bravery challenged starts with this movie. It gets him into trouble and makes his situation worse four times in this movie alone:
  • He initially follows Doc's plan to pretend to be his own son and refuse to join Griff and his gang in the robbery; however, as he starts to walk away, Griff calls him a chicken, and Marty gets into a fight with the gang that results in a chase scene in the town square.^note This actually ends up working out nicely because Griff and his gang get arrested for crashing into the courthouse, but it still put Marty in an unnecessary amount of danger first.
  • We learn that this is the reason Marty's life isn't going very well in 2015: at some point in the past^note which turns out to be in 1985, the very next day after returning home from the events of Part I, as revealed in Part III, Marty was baited into participating in a drag race with Needles due to the latter calling him chicken. This resulted in Marty crashing his car and breaking his hand, which led to him losing a lot of his self-confidence, giving up a career in music, having to pay damages, and Jennifer only staying with and marrying him out of sympathy.
  • What's more, he apparently never learned from this or overcame this flaw at all, since he lets Needles goad him this way, again, into participating in an illegal deal that he knows is a bad idea and could get him fired. Sure enough, within seconds of hanging up with Needles, Marty's boss Ito T. Fujitsu, who was monitoring the call, contacts him to fire him for his involvement.
  • After Marty has stolen the Almanac back from Biff, the latter catches up with him and challenges him to a fight. Marty starts to just leave, since he's completed the mission he came to 1955 to complete in the first place, but once Biff calls him a chicken, Marty stops in his tracks and prepares to fight him... which causes him to get hit in the face with the door (by his unknowing past self, no less), stunning him long enough for Biff to take back the Almanac and leave, and requiring him and Doc to chase Biff down in his car to retrieve it. It causes further problems since because Doc and Marty are still in 1955 when the storm arrives, the DeLorean gets struck by lightning and Doc ends up getting sent to the Old West, leading to the events of the third movie.
• Beta Bitch: "Spike" is implied to be Griff Tannen's girlfriend, and seems to be second in command in his Gang of Bullies.
• Between My Legs: Marty stands over Biff and his mistresses while asking about the almanac.
• Big Bad: Biff Tannen. An elderly Biff from 2015 steals the Delorean time machine and gives an almanac of sporting events from 1950-2000 to his younger self from 1955. Biff in this new timeline uses the information to make himself rich and famous, turns Hill Valley (and possibly the state of California and other places) into a Crapsack World, and murders George McFly in 1973, forcing Marty's mother Lorraine to marry him. After Doc and Marty go back to 1955 to retrieve and destroy the almanac, the Biff from that time period serves as a Climax Boss.
• Big "NO!":
  • 2015 Marty after Fujitsu fired him for his illegal transaction moments before.
    2015 Marty: NOOOOO! I can't be fired! I'm fired! AAAAAAHH!
  • Marty after finding out that Biff-A married Lorraine-A.
  • And again after finding George's grave; he starts out with a Little "No", before it becomes this.
    Marty: No! Oh, please God, NO!
  • Just like the previous movie, TV edits of this movie have Biff yell one of these instead of "SHIIIT!!" as he's about to crash into the manure truck after his confrontation with Marty in the tunnel.
• Big, Screwed-Up Family:
  • The McFlys again (in this case, Marty's family with Jennifer). Grandma Lorraine and Grandpa George can only shake their heads in bewilderment, inverting the plot of the first movie.
  • The Baines-McFlys-Tannens-A's also count, but counting them as just "screwed-up" is a nice way of looking at their current situation.
• Big "YES!":
  • Marty when he thinks he got his hands on Gray's Sports Almanac from Mr. Strickland's trash can in 1955, only to find out by opening the contents of the book that it was actually Oh Là Là! with the sports almanac cover over it.
  • He also gives one upon seeing George punch out Biff.
  • And again with Marty after Biff crashed into a manure truck (again).
• Binocular Shot: When Marty uses binoculars to spy on the Tannens' house, at the dance in 1955, and when the DeLorean is flying above Biff's car. Doc uses futuristic ones in 2015.
• Bitch Slap: In 1985-A, Biff-A slaps Lorraine-A when she tries to mouth off at him, hitting her so hard that she falls to the floor.
• Biting-the-Hand Humor: "Shark still looks fake." Also doubles as Self-Deprecation since Steven Spielberg was the executive producer for the series, and his son Max Spielberg directed Jaws 19.
• Blatant Lies:
  • When future Marty's boss confronts him about participating with Needles in an illegal scheme, Marty claims that he was setting Needles up as part of a sting operation. His boss doesn't buy it for one second. Then, when Lorraine finds the fax about Marty being fired and asks him about it, Marty claims it was just an office joke.
  • When Strickland asks Biff if he smells liquor, Biff says he wouldn't know what liquor smells like, "because I'm too young to drink it."
• Borrowed Without Permission: Doc "borrows" some old newspapers from the closed-down Hill Valley Library in 1985-A.
• Book and Switch: Biff hides a girly magazine inside the dust jacket of the sports almanac, which Marty mistakes for the real thing. An earlier scene in 2015 established the dust jacket for the purpose of this scene.
• Breast Expansion:
  • Lorraine-A was forced by Biff-A to get breast implants. Even Marty is alarmed.
    Marty: You're so... big!
  • Also, one of the six channels that Marty Jr. is watching in 2015 has a commercial for inflatable breast implants.
• Briefcase Full of Money: Upon returning to 1955, Doc unveils a silver attaché case full of emergency funds. It contains different denominations from various time periods.
• Broken Bird: Lorraine-A is a shattered woman, trapped in an abusive/loveless marriage to Biff, staying with him only so that her children can live in relative comfort.
• Bulletproof Vest: Biff Tannen watches a movie set in the Wild West where a man survives gun shots thanks to this, as foreshadowing for the next sequel
• Can't Get Away with Nuthin': It takes only a few seconds for Future Marty's boss, Ito T. Fujitsu, to call him and send him the "YOU'RE FIRED!!!" faxes after Marty engages in an illegal business deal with Needles, since Fujitsu was monitoring the call the whole time.
• Can't Kill You, Still Need You: A non-lethal variation after Doc and Marty head back to 1955. Marty's mission is to track down 1955 Biff, tail him, and wait until 2015 Biff inevitably shows up with the Almanac. Here, Doc gives Marty explicit instructions: do not interfere with that event. Old Biff must believe he's accomplished his own mission so that he'll leave 1955 and bring the DeLorean back to 2015. If he doesn't, then of course Marty and Doc will never leave 2015, discover 1985's been altered, and be able to head back to 1955 to try and set things right. Once he's gone, then grab the book at any cost.
• Can't You Read the Sign?: When going to the future Hilldale, Doc Brown lands the flying DeLorean... on a part of the road with a large "NO LANDING" painted on the ground.
• Captain Obvious:
  • "All I have to do is bet on the winner, and I'll never lose." Of course, this is completely in character for Biff to say.
  • The "Wallet Guy". Granted, Marty didn't take Biff's wallet (he took the sports almanac), but Biff was definitely re-knocked out and robbed.
• Career-Ending Injury: In the initial timeline, a car accident ends Marty's rock career before it even took off the ground.
• Car Fu: Attempted by Biff Tannen when he tries to run Marty down in the tunnel. Marty himself only has the hoverboard with him, so he knows he's outmatched. Luckily, Doc rescues him from above, and Biff is so shocked upon seeing the hovering Delorean that he ends up crashing into manure.
• Cassette Futurism: The store, as well as the Café '80s, are in-universe examples. The whole 2015 segment in the same movie heavily features this kind of aesthetic, but it's implied that they also have some form of advanced digital technology (though we never see it directly in the movie itself).
• Celebrity Paradox:
  • Cafe '80s in 2015 shows '80s TV shows, including Family Ties (starring Michael J. Fox) and Taxi (starring Christopher Lloyd). A thrift store also has a Roger Rabbit plush in the window as well, also starring Lloyd, while Charles Fleischer, who voiced Roger, appears as Terry the mechanic.
  • A subtle one: when USA Today released a defictionalized front page article that closely resembles the one shown in the movie, there's one story about a movie adaptation of A Match Made in Space, based on George McFly's novel. According to the article, it will be directed by Robert Zemeckis, and Christopher Lloyd is a cast member.
  • Marty sees an advertisement for Jaws 19. Lea Thompson (Lorraine) was in Jaws 3-D.
• Cerebus Retcon: In the last scene of the original Back to the Future, Doc, Marty, and Jennifer take off in the newly-modified DeLorean to travel to the future. In this movie, we see that Biff saw the time machine taking off and in the 2015, the elderly Biff sees it again and figures out its true nature, deciding to steal it for his own purposes.
• Chalk Outline: In 1985-A, Marty comes across the outlines of two drive-by shooting victims—complete with puddles of blood on the ground—shortly after he flees from what was originally his 1985 house in this timeline.
• Chase Stops at Water: Inverted with the hoverboard chase — Marty is the one unable to cross the water, because his hoverboard stalls out halfway across, while Griff can thanks to his rocket-powered board (though it doesn't end up helping him in the end).
• Chekhov's Boomerang: The Mattel Hoverboard Marty takes in 2015 serves its purpose well in its first scene. We think it's done after that, until this set up pays off in the Battle for the Book tunnel chase when Marty rides it again. It'll get used again in the third film.
• Chekhov's Gun:
  • In 1985, Biff tries to give Marty a new matchbook for his company before seeing him take off in the DeLorean with Doc. Later, in 1985-A, Marty takes a matchbox from Biff-A's office, and after destroying Gray's Sports Almanac (with a match from said matchbook), he sees its writing change from "Pleasure Paradise" to "Auto Detailing".
  • The billboard ribbon that gets stuck on the DeLorean does come in handy when Doc uses it to save Marty in the tunnel from Biff.
  • During Marty's struggle with Biff in the tunnel to take back the Almanac, he and his hoverboard, floating alongside Biff's car, almost get hit by a truck. This is the same manure truck Biff crashes into (again) a few minutes later. Doubles as Five-Second Foreshadowing.
• Chekhov's Gunman: Buford Tannen, the Big Bad of Part III, is first shown in the Biff Tannen Museum biographical video.
• *Click* Hello: Mr. Strickland thinks Marty's the son-of-a-bitch who's been stealing his newspapers from his porch.
• Coat, Hat, Mask: A variation with the outfit Marty wears in 1955: a leather jacket, fedora, and Cool Shades.
• Compound-Interest Time Travel Gambit: A scene strongly implies Doc Brown engages in this. Marty needs some money from the timeline they're in, and Doc opens a briefcase with neatly arranged stacks of bills of various colors and sizes. The comic books show how Doc got some of his money by traveling back to 1938, buying several copies of Action Comics #1 (the first appearance of Superman), then going to 2015 and selling them at auction for millions.
• Continuity Nod: In the first film, Marty tells 1955 Doc something along the lines about how weathermen can't actually predict the weather. By 2015, Doc remarks that the rainstorm ended right on the tick, and that it's a shame that the post office isn't as efficient as the weather service.
• Contrasting Sequel Setting: The first movie is largely set in 1955, while this one goes to 2015 and an alternate 1985 before going back to 1955. The setting for all four cases is Hill Valley, so the contrast is based on it has fared in each of them.
• Contrived Coincidence:
  • First, Doc knocks out Jennifer, after being the one to insist on bringing her along to the future. Then, for some reason, he and Marty put her on the cold, hard ground in an alley instead of just leaving her in the DeLorean. Then it just happens that the knockout device didn't have enough power for Marty Junior because Doc used it on Jennifer. Then Marty's Berserk Button of people calling him a chicken manifests despite not being hinted at in the first movie, and he gets in an altercation with Griff and his gang instead of just walking away. Then Doc parks the DeLorean where Old Biff can see. Then Marty Junior bumps into Old Biff so he can see that there are two Martys. Then he eavesdrops on Marty and Doc, who don't bother to worry about whether someone might be listening while they're discussing time travel, which Doc explicitly wants to keep secret. Then, when Marty grabs the ill-fated sports almanac, it falls out of the bag. Then, thanks to them inexplicably leaving Jennifer in an alley, she gets found and taken home and they have to go get her. Then, despite Doc telling Marty to stay with the car, he wanders off while Biff steals the time machine.
  • Lampshaded by Doc, who ponders why Old Biff chose to travel to November 12, 1955 to give himself the Almanac, the same day and night of the school dance, the huge storm, and Marty's original return to the future. He wonders if there's some cosmic significance to the date, as if it was a junction for the entire space-time continuum — or if was all just one huge coincidence. It's possible that Old Biff chose that particular date because of the football game he shows Young Biff to prove that the Almanac is for real, given that it was a very close call. If Old Biff had called the answers to a game where one side won by a huge margin, Young Biff would say it was just a lucky guess. More likely he views that night — when George stood up to him for the first time and got the girl Biff was obsessed with — as the night his life went wrong.^note A deleted scene has Terry in 2015 mention November 12, 1955 as the date of the lightning storm — and also that he had fixed Biff's car on that date, as later seen in the movie. It was meant to be the reasoning behind Biff choosing that particular date.
  • 1985 Jennifer just happens to be in the 2015 house at the exact moment Marty gets fired. She also just happens to hear Lorraine tell the story about Marty’s car accident.
• Cool Car: Several from the first movie re-appear. However, a couple of the 2015 cars also double as a Shout-Out.
  • The Star Car from The Last Starfighter is parked on the street during the hoverboard chase.
  • Two Spinners from Blade Runner can be seen (a black one during the hoverboard chase and one in Hilldale).
  • The majority of the cars seen are either concept/prototypes (Pontiac Banshee IV, Pontiac Fiero, Oldsmobile Aerotech II), specialty/Kit Cars (Gene Winfield's Strip Star, Owosso Pulse), or then-new, available cars (Ford Probe, Ford Mustang) with extensive body modifications.
  • The flying taxicab Biff uses to get to Hilldale is a Citroën DS, a car which was introduced in 1955.
  • Marty suggests just landing the DeLorean on Biff's car to get the almanac back. Doc Brown points out that Biff is in a solid steel car from 1955 and they're in a DeLorean. "He'd rip through us like tin foil."
• "Could Have Avoided This!" Plot: Marty realizes that the alternate 1985 would never have happened if he never bought the sports almanac in the first place.
  Marty: It's my fault... this whole thing's my fault! If I hadn't bought that damn book, then none of this would've happened!
• CPR: Clean, Pretty, Reliable: Subverted — Biff comes to just as someone (named "CPR Kid" in the credits) asks, "What's CPR?", and Marty knocks Biff out again. Amusingly, the "Universal Animated Anecdotes" included in the DVD had to clarify that CPR does not mean punching someone in the face.
  From the Actual DVD Commentary: No, kids, that's not CPR.
• Crapsaccharine World: 2015 Hill Valley. Yes, it is very clean, efficient, people appear happy, and it even has flying cars and hoverboards. But beneath it is the crapsack: you can get sentenced for twenty years for relatively minor crimes; lawyers are abolished (which sounds hilarious until you need one, like Marty's kids after they get caught); Hilldale is flooded with "tranqs, lobos, and zipheads"; thumb bandits are on the loose; and mega-corporations have their employees conspire to get Marty fired. Oh, and it costs fifty dollars for a single Pepsi.
• Crapsack World: 1985-A. "Hell Valley" indeed. It's been all but destroyed, crime runs rampant, and Biff's political clout prevents anyone from touching him.
• Cross-Cast Role: Michael J. Fox plays Marty's daughter Marlene.
• Cue the Rain: It starts raining soon after lightning strikes the time machine and Marty is left stranded in the past again. Justified, of course, because this is the same storm that played a role in sending Marty back to the future in the first film, and there were all sorts of signs of a storm brewing the whole time anyway.
• Curse Cut Short: During Marty's confrontation with Biff on the rooftop in 1985-A, Marty says "You son of a...", but is cut off when Biff cocks his gun at him, taunting him into trying to finish that insult and clearly will shoot him if he does.
• Cybernetics Eat Your Soul: Marty is warned that the cyborg asshole Griff "has a few short circuits in his bionic implants."
• Cyberpunk:
  • Downplayed if not defied. According to the behind-the-scenes featuretteinvoked, Robert Zemeckis intended the future he wrote to be a counterpoint to the darker dystopian visions of cyberpunk, Blade Runner in particular. Hill Valley really is "a nice place to live" in 2015; technology seems to make life better instead of worse, and the police don't seem overly concerned for their own safety even in the rough neighborhood of Hilldale. That said, there are apparently no lawyers in 2015, hoodlums like Griff run rampant with cybernetic enhancements, and there are still areas of poverty.
  • The Hill Valley of 1985-A plays this straighter, albeit without the cool tech: enormous poverty, a broken political system, and a corrupt billionaire having absolute power over society.
• Cyberpunk with a Chance of Rain: Subverted. The DeLorean lands in a back alley, gearing up for a dark, cyberpunk setting... and then the skies clear.
• Dark Action Girl: Leslie "Spike" O'Malley in 2015. She's every bit as tough, vicious and nasty as any male member of any Tannen gang.
• Darker and Edgier: Considered to be the darkest film in the trilogy, since the bad guy essentially wins at the end of the first act, resulting in a horrifying Crapsack World Bad Present that the protagonists have to spend the rest of the movie trying to fix. In the first film, Biff was a highschool bully, barring the rape scene. Part II takes his villainy up several notches to outright murder.
• Darkest Hour: Often cited as the darkest movie in the trilogy, since Biff "wins" in 1985-A and it's up to Doc and Marty to fix the timeline.
• Dark Reprise: The main title is a mildly dark reprise of the first movie's theme music. It's played on lower instruments and, while still sounding triumphant, there is a certain foreboding to it.
• Deadly Disc: Marty uses an ashtray with star-like blades sticking out in Biff's office.
• Decided by One Vote: The Biff Tannen museum, while mentioning Biff successfully lobbying to legalize gambling, shows a clip of a newspaper that describes the initiative as being passed by a one vote margin.
• Delayed Ripple Effect: There's a deleted scene in which Old Biff, having returned from the past and set up the Bad Future, emerges from the DeLorean and suddenly fades out of existence. This is because in the bad future, Lorraine gets fed up and shoots him in the 1990s. The scene was deleted mostly because it was unclear what was happening and no one was around to explain why, but that's what the filmmakers said they were aiming for. It's interesting because in the film, we see Old Biff hang around in 1955 with no ill effects, but once he jumps 60 years later, the ripple effect catches up with him faster than Young Biff actually makes use of Old Biff's plan in San Dimas Time. But we also see Old Biff break off the top of his cane as he leaves the DeLorean, and the cane doesn't fade out because it's still in the DeLorean when Doc and Marty return to it — that's how they know what Old Biff did. It suggests the DeLorean has a sort of capsule effect that protects anything in it from time ripples, and that Old Biff faded out as soon as he stepped out of the car.
• Deliberate Values Dissonance: A futuristic example occurs when, explaining a newspaper report a shocked Marty is reading about his son getting swiftly sentenced to a long prison term, the Doc nonchalantly points out that "the justice system works swiftly in the future now that they've abolished all lawyers!" (One need only think about the negative implications of that...)
• Denser and Wackier: Although the Crapsack World of 1985-A takes the film into darker territory than its predecessor, Part II is this for the trilogy. While the first and third movies are relatively straightforward Fish out of Temporal Water stories in existent time periods, Part II ups the adventure quota with multiple Set Right What Once Went Wrong scenarios that require multiple time jumps. The different time periods here all feature more fantastical elements than in the other movies; it starts with the protagonists journeying into the distant future (with a lot of broad comedy aimed at the present-day 80s culture), then to the aforementioned alternate crapsack timeline, followed by a jump back into 1955 that has two temporal-fish Martys existing at the same time. The film also starts the franchise tradition of the actors playing multiple generations of the McFly and Tannen bloodlines, rather than just playing the younger or older versions of themselves.
• Determinator: Western Union. Upon receiving a letter in 1885 with specific instructions to deliver it to somebody not yet born, at a spot in the middle of nowhere, the company sees to it that a representative is on that spot, with that 70-year-old letter. How much of a delivery fee did Doc pay?! (Justified, however, in that the courier admits the entire branch was betting on whether someone would actually be at that place and time to accept the package.)
  Western Union Man: Looks, like I lost! [laughs]
• Did Not See That Coming: This nearly gets Marty killed when he interrogates 1985-A Biff about how he acquired the Almanac. While Marty knew going in such an interrogation was going to be dangerous (given how out of control the alternate Biff is), neither he or Doc foresaw the possibility that 2015 Biff had warned his younger self about the Partners in Time — and to take precautions if either of them showed up asking about the book.
• Didn't Think This Through:
  • Much of the plot happens because Doc was careless and didn't mind that an outlandish event such as a flying car disappearing in the air, in broad light, in the middle of a residential neighborhood in 1985 could be spotted by someone, triggering uncontrollable ramifications.
  • While it's not actually pointed out in the film, it's still made clear that Doc made a serious oversight with the design of the Time Circuits: the absence of a recorder or data log to keep track of all the time jumps. This wasn't an issue in the first film, but it now comes back to bite him and Marty in the ass after 2015 Biff steals the DeLorean. Since the Time Circuits don't keep a record of Time Jumps beyond the last departure (and because Doc and Marty Failed a Spot Check when returning from 2015), they don't initially know where and when 2015 Biff gave the Almanac to his younger self. All they know is that it was at some point prior to his 21st Birthday in 1958 (when Biff first used the Almanac), but that also doesn't narrow it down much.
• Different World, Different Movies: There's a Jaws 19 in the alternate future during 2015.
• Disproportionate Retribution:
  • 1985-A Strickland threatens to shoot Marty's testicles off for apparently being the son-of-a-bitch who was stealing his newspapers.
  • Biff-A keeps Lorraine-A under his control by threatening to put her, Linda-A, Dave-A, and Marty-A in jail if she walks out on him alongside her brother Joey (who is still a jailbird even though 1985-A is a different timeline).
• Domestic Abuse: To no one's surprise, Alternate Universe-Biff is a philanderer who's grown bored of Lorraine, keeping her around only as a Trophy Wife and a symbol of his victory over George. Marty goes berserk when Biff-A shoves her to the ground, earning a punch in the gut. That's right, Biff-A even slugs his step-children. Not to mention he threatens to financially cut off her three children and throw them in prison if she tries to leave him.
• The Door Slams You: Marty does this to himself at the school dance, or rather, his stuck-in-1955 self doing it to his current self.
• Dope Slap: Old Biff dope-slaps Young Biff for mangling a joke after giving him the Gray's Sports Almanac. And no, they don't explode (specially since Young Biff is too stupid to recognize himself).
  Young Biff: Why don't you make like a tree and get outta here?
  Old Biff: [whap!] It's "LEAVE", you idiot! "Make like a tree and leave". You sound like a damned FOOL when you say it wrong!
  Young Biff: ALRIGHT THEN, LEAVE!!
• Double Take:
  • Jennifer does one when she lays eyes on the 47-year-old, drastically different Marty from the closet she's hiding in.
  • A double-double take (quadruple take?) when Old and Young Jennifer meet. Each look at the other, go back to entering/leaving the house, then whip around and stare at each other a few moments, before throwing their hands up and screaming "I'm old!/I'm young!" and passing out. In opposite directions, of course.
  • While driving his car, Biff distractedly looks to the side, but doesn't react immediately at the sight of Marty trying to steal the Gray's Sports Almanac.
• Double Vision: During production, this movie used this effect to allow Michael J. Fox to play all the characters at the dinner table; Industrial Light and Magic used a special robot controlled camera to allow camera movements while making sure that all the backgrounds lined up. It was also used in scenes where Biff Tannen and Doc Brown from the future met their 1955 selves, although not without a great deal of painting the frame (see the scene where Old Biff throws the book at Young Biff). The second film does a variation on the usual "split-screen" effects when the flying DMC-12 lands "behind" a streetlight for a perfect model-to-car transition.
• Down to the Last Play: How 2015 Biff shows "Gray's Sports Almanac" is real. With less than a minute on the clock, 2015 Biff tells 1955 Biff that UCLA will win, despite them currently trailing Washington 16-17, and 1955 Biff scoffs at the idea, since even the announcer thinks the game is as good as over. 2015 Biff turns up the radio, and the commentator announces that UCLA made a last-second field goal, winning the game 19-17.
• Dramatic Gun Cock: Happens twice as Marty faces the Biff Tannen of 1985-A:
  • First, after Biff tells Marty about how he got the Gray's Sports Almanac from the old Biff of 2015:
    Biff: He told me one more thing: He said, "Someday, a kid or crazy wide-eyed scientist might show up asking about that book. And if that ever happens..."
    [Biff pulls out a pistol and cocks it, making Marty nervous]
  • Afterwards, as Biff pursues Marty onto the roof of his casino/hotel:
    Marty: What about the police, Biff? They're gonna match up the bullet to that gun.
    Biff: Kid, I own the police! Besides, they couldn't match up the bullet that killed your old man.
    Marty: You son of a—
    [Biff cocks his pistol]
• Dramatic Irony:
  • 2015 Hilldale is quickly established as a rough neighborhood of disrepute home to unsavory characters, with the cops even commenting that the whole place ought to be torn down, which indicates how bad Marty's future is if he's stuck living there. However, 1985 Marty comes from a time where Hilldale is the hot new development for affluent people, so he sees himself living there as a sign that he's made it big.
  • If the viewer's paying close attention to the Time Circuit readouts (specifically the Last Time Departed display) before Doc and Marty leave 2015, they'll know where and when 2015 Biff went long before Doc and Marty figure it out.
  • In 1985-A, it is established that Lorraine ends up reluctantly marrying the obscenely rich Biff. Earlier in 1955, when Biff torments Lorraine, she responds, "Biff Tannen, I wouldn't be your girl even if... even if you had a million dollars!" Granted, he had to kill George to make that happen.
• Dramatic TV Shut-Off: Halfway during the movie's story, Marty and Doc figure out that Biff Tannen became filthy rich due to having gotten the sports almanac that was purchased from the future. So Marty infiltrates through Biff's luxurious building and, upon reaching his spa room where he's watching TV with two naked women, he grabs the TV remote to turn it off and then throws it at the spa's water. While Biff is merely baffled over it at first, he realizes how serious the situation is when Marty tells him that he knows about the almanac, so he asks the women to go away.
  Marty: Party's over, Biff.
• Droste Image: Biff in his office, standing in front of a painting portraying him in a similar pose◊.
• Drowning My Sorrows:
  • Lorraine-A is a bigger alcoholic than in the original 1985 from the first film. It's understandable, since the Lorraine of the original timeline had a dysfunctional marriage to George, but certainly not an abusive one like Lorraine-A.
  • A deleted scene has 2015 Marty Sr. discovering 2015 Jennifer lying unconscious in their house's doorway (having fainted from the shock of encountering her younger self from 1985), and his reaction is a resigned sigh followed by "She's tranked again", implying that 2015 Jennifer (trapped in an unhappy marriage with Marty) regularly intoxicates herself with chemicals to the point that she would arrive home so drunk that she'll pass out cold as soon as she steps through the door, and Marty is used to this.
• Drunk with Power:
  • The first film established Biff as a petty schoolyard bully who would continue to be so in his adult life in one timeline, or would become relatively harmless if a little sneaky in a better timeline. This film reveals how Biff would become an absolute monster if he had access to real wealth and power, even happily committing murder and getting away with it.
  • Marty might have turned out worse than he is if he had succeeded in using the sports almanac to get rich by betting on the outcomes of sports games.
• Early-Bird Cameo: Buford "Mad Dog" Tannen, main antagonist of Part III, briefly appears in the informative video playing outside the Biff Tannen Museum.
• Early Installment Character-Design Difference: The picture of Buford Tannen from the museum video was an early makeup test, which is why he looks different than when we finally see him in Part III (Buford is pictured with a Beard of Evil instead of a moustache). It's confirmed that if they had the time, they would have replaced that picture with one featuring his final look.
• Easily Forgiven: When Doc explains that the whole alternate 1985 issue was caused by the Sports Almanac that Marty bought with plans to profit from it (an idea that Old Biff essentially stole from him), Marty has an "It's All My Fault" crisis. Doc isn't upset with him; he essentially says "what's done is done", and prefers to focus all their attention on fixing things immediately.
• The Easy Way or the Hard Way: Directly quoted when Marty gets knocked out by Biff's gang.
  3-D: [WHACK!] The easy way.
• Electronic Speech Impediment: The barkeeps at the '80s Café are avatars of Ronald Reagan, Ayatollah Khomeini, and Michael Jackson, all of course with a deliberately added Max Headroom-style impediment.
• Equal-Opportunity Evil: While Biff has a "white guys only" rule in 1955, as did his great-grandfather Buford in 1885, Griff Tannen's cybernetically-enhanced teenage gang includes at least one Asian and a blonde girl.
• "Eureka!" Moment: After realizing all he did was find Biff's dirty magazine in Strickland's office (and that Biff still has the Almanac), Marty laments to Doc over the walkie talkie that he has no idea what to do now or how he's going to find Biff... only to hear the sound of a certain struggle going on in the parking lot.
  Marty: OF COURSE! [to Doc] I gotta go, I got one chance, my old man is about to deck Biff!
• Evil Lawyer Joke: "The justice system works swiftly in the future now that they've abolished all lawyers." Note that Doc does not necessarily say that as good news. Specifically, the line explains how Marty’s future son was tried, convicted, and sentenced to 15 years in prison within 2 hours of his arrest. Considering the context of the line it's more likely that no lawyers mean no protection from the State Sec.
• Evil Learns of Outside Context: When Biff Tannen learns that Doc Brown and Marty have a Time Machine, he uses it (along with the sports almanac Marty bought but Doc threw away) to go back in time to 1955 and make himself wealthy. By the time Marty and Doc realize what's gone wrong, they wind up in a nightmarish version of 1985 where Biff has almost total control of Hill Valley.
• Evil Sounds Deep: Or, rather, electronic in the case of Griff. Additionally, 1985-A Biff, who is the most evil incarnation of the character, also has the deepest voice of any of them.
• Evil Tower of Ominousness: Biff-A converted Hill Valley's historic courthouse into a gaudy testament to his own penis — er, wealth and prestige.
• Exact Eavesdropping: Marty and Doc have the misfortune of being stalked and heard by Biff during their argument about time travel for profit.
• Exactly Exty Years Ago: Doc Brown chooses to go thirty years into the future specifically because "it's a nice round number", but at the end of the film the time machine gets struck by lightning and goes back to 1885, which is 100 years before the start of the first film. It was caused by the destination display glitching and moving one number in the hundreds' slot.
• Expelled from Every Other School: This apparently happened with the alternate Marty, since when the original Marty turns up in 1985-A, the assumption is that he was, "kicked out of another boarding school."
• Explain, Explain... Oh, Crap!:
  • When Doc figures out he and Marty can just pick up Jennifer at her and Marty's future home, Marty is happy at the prospect of meeting his future self, but Doc starts explaining why it mustn't happen until he, by doing so, figures out there's a high probability Jennifer will meet her future self.
  • After Doc reveals to Marty that Old Biff helped Past Biff get rich with the Sports Almanac, leading to the Bad Present, Marty complains how Old Biff stole his idea simply by eavesdropping. Marty then stops and realizes that this all happened because he even considered the idea in the first place.

Tropes F-N

• Failed a Spot Check:
  • During the exchange between Griff's gang and both Marty and Marty Jr., after Marty Jr. is thrown over the counter and lands on the floor next to our Marty, Marty tells him to keep quiet rather than say he's in on Griff's opportunity, then puts on Jr.'s hat and stands up. Somehow, Griff must be too thick-headed to notice that Marty visibly has a red t-shirt underneath his jacket, whereas Marty Jr. has a white shirt, or the fact that Marty Jr.'s left sleeve is ill-fitting, unlike Marty's. Not to mention that his eye color changed from brown to blue, and Marty Jr. seemed to be wearing some sort of hair gel while Marty wasn't.
  • The multiple times that people should be seeing two versions of Marty or Doc. Biff's gang in 1955 should see a Marty on stage and in the opposite wings, and Doc literally meets himself. At least Doc's a little absent-minded, plus 1985 Doc makes sure his past self doesn't see his face.
  • Biff repeatedly fails to notice Marty hiding in the back seat of his car, particularly when Marty is loudly talking to Doc on the walkie-talkie while Biff is driving.
  • When they leave 2015, Doc and Marty both fail to notice that the "Last Time Departed" display on the Time Circuits now reads November 12, 1955 instead of October 26, 1985 as it should. They likewise fail to notice the now-empty Blast from the Past bag and the cracked top of Old Biff's cane inside the car. Both lapses are justified, as Doc and Marty were distracted by the close call with the 1985 and 2015 Jennifers (plus Doc's attention was also focused on dismantling the time machine upon their return home).
  • When they initially think they've returned to 1985, Marty and Doc miss visible and obvious clues that something's very wrong (from bars on the windows of Jennifer's home to the defaced Lyon Estates statues).
  • Subverted when Marty Jr. somehow recognizes the 1985 Jennifer when he passes her in the hall.
  • Despite the Almanac being clearly visible in 1958 Biff's jacket pocket during his first big win, nobody at the Race Track (employees or journalists) noticed it.
• Failed Future Forecast:
  • The brief mention of Queen Diana's visit to Washington D.C. in 2015 may have been intended as a throwaway gag, but it ends up mis-predicting history on several counts. Firstly, Diana divorced Prince Charles two decades before the date of her state visit in the film. Secondly, Diana wasn't even alive in 2015, due to her tragic death in a car crash in 1997. Thirdly, even if Diana had been alive and still married to Charles, she wouldn't have been the queen in 2015, as Charles' mother Elizabeth II was still alive and on the throne by the time 2015 rolled around in real-life (in fact, that year saw her surpass Queen Victoria's record as the longest-reigning British monarch).
  • Marty working for a Japanese boss was keeping the 1980s view that Japan was returning to superpower status and would overtake the United States. But just after 1989, Japan would enter its Lost Decade and has remained in an economic and social spiral.
• Faint in Shock:
  • Marty's girlfriend Jennifer is accidentally brought into her future home. As she's about to leave, she comes across the 2015 version of herself:
    Jennifer (seventeen): [gasps] I'M OLD!!
    Jennifer (forty-seven): [gasps] I'M YOUNG!!
    [both faint simultaneously]^note This faint lasts a ridiculously long time: Doc predicts that Jennifer would stay unconscious for several hours based on the severity of the shock, which very rarely happens in real life. Jennifer is placed on her house's front porch swing just after 9 at night, and it is already almost noon the next day by the time she finally wakes up in Part III
  • 1955 Doc Brown faints at the end, after Marty (whom he had just sent away in the time machine) reappears behind him.
    Doc: [screams upon seeing Marty]
    Marty: Okay, relax, Doc. It's me, it's me! It's Marty!
    Doc: No! It can't be! I just sent you back to the future!
    Marty: No, I know. You did send me back to the future, but I'm back. I'm back from the future.
    [Beat]
    Doc: Great... Scott! [faints dead away]
  • In the original script, Marty was supposed to faint upon learning that Biff married Lorraine in 1985-A. In the final product, this was changed to him screaming and being knocked out by Biff's gang.
• Fake Shemp: Word of Bob Gale says that Crispin Glover got an ego and started making outlandish demands for his return in the sequels. Gale and Zemeckis decided to forget Glover and get creative by using a double actor and some nifty tricks with stock footage and computer effects. It backfired on the producers and Glover sued. The suit was settled out of court and the Screen Actors Guild revised their rules on stock footage use. It should be noted that Glover is still listed in the film's credits as "George McFly in footage from Back to the Future".
• Famous-Named Foreigner: After Japan Takes Over the World, Marty McFly addresses his boss as Fujitsu-san. The problem is Fujitsu is only the name of a corporation; it is not a Japanese surname. It's a bit like having a character named Mr. Kodak.
• Fan Disservice: Lorraine in 1985-A has breast implants and a cleavage-revealing top...because her abusive husband Biff made her get the former and it's quite likely he makes her wear the latter. Her looking guilty when Marty exclaims she's "so... big!" doesn't help.
• Fantastic Romance: Compared to the first movie, Part II puts the romance into the background a little bit, but the emotional stakes are still there with Marty trying to return to Jennifer. Jennifer herself gets a grim view of their future together.
• Fashionable Asymmetry: Marty Jr. has his left sleeve much longer than his right.
• Financial Abuse: Biff-A indulges in this too, unsurprisingly. When shoving Lorraine around and punching Marty in the Alternate Timeline causes Lorraine to threaten to leave, Biff resorts to this, claiming he will cut Lorraine and all her children off, leaving them with tons of debt and most likely jail time, leaving her no choice but to stay.
• Firing Day: In the future of 2015 seen in the movie, Jennifer witnesses Marty being fired after he is shamed into participating in an illegal scam with Needles. This highlights just how much of a Future Loser Marty will become, and how much his life is ruined by the fact that Nobody Calls Me "Chicken"!. She judges just how much the future has changed when, in Back to the Future Part III, the "You're Fired!" fax she brought back is erased.
• Five-Token Band: Griff's gang includes a blonde girl and an Asian guy, whereas the other Tannens in the series (Biff and Buford) have gangs composed exclusively of white males. Perhaps the filmmakers assumed there would be more diversity in the future.
• Flying Car: The DeLorean flies in this movie, plus many other examples in 2015.
• Forced Perspective: The Lyon Estates site, and the tunnel.
• Foreshadowing:
  • When Marty and Dr. Brown return a sleeping Jennifer back on the porch of her home in 1985-A, Marty noticed something a bit off.
    Marty: I don't remember any bars on these windows...
  • For that matter, if you look closely from the moment they enter the alternate 1985, you'll notice that things are slightly off: aside from the bars on the windows, Jennifer's house and yard look slightly run-down, her father's car has been wrecked, and the entrance to Lyon Estates is covered in graffiti and a pack of feral dogs run by after Doc and Marty drive past.
  • When the "DESTINATION TIME" readout on the time circuits flash to "JAN 01 1885 12:00AM" and Doc remarks "Damn, gotta fix this thing." By the end of the film, Doc relates in a letter that he jumped to that time and had already been there for eight months.
  • As Doc is punching in the "Destination Time" of October 26, 1985, 9:00PM to return the group from 2015 to their home time, if you look quickly at the "Time Recently Departed" field, you'll see the date of "November 12, 1955, 6:38PM", hinting at the Time Machine's theft by Old Biff Tannen.
  • Biff-A is watching A Fistful of Dollars, and crows when Clint Eastwood showed he was wearing a stovetop under his poncho, "A bulletproof vest! The guy is brilliant!" Guess how the showdown in Part III is resolved? Also doubles as a Call-Back to how Doc saved himself from the Libyans' attack in the first movie.
  • Again, Buford Tannen's cameo during the Biff Tannen Museum's introductory video. Not only does this set up Buford's role in Part III, but his nickname of "Mad Dog" tells you everything you need to know about Biff's ancestor.
  • Doc tells Marty that his visit to the rejuvenation clinic "added a good 30-40 years" to his life; Word of God said this ensured he could start a family with Clara and be around long enough to see their sons grow up in Part III.invoked
  • Doc tells Marty that telling the police they were time travelers in order to save Jennifer would get them committed. Guess what Doc's fate is in 1985-A?
  • It's blurry, but when Strickland is thumbing through what is supposedly Gray's Sports Almanac after taking it from Biff, you can see pictures... of women.
  • Another bit: it's pointed out when Marty is buying the Almanac earlier in the film that it comes with a dust jacket because it's an antiquated concept in the distant, futuristic year of 2015. Sure enough, Biff took the cover off it at some point and put it over a different book, leading to a Book and Switch situation. Similarly, as 1985-A Biff shows Marty the almanac, you'll notice the cover is gone and the pages are aged after 30 years.
  • Spread out over two movies, but near the end, when Marty proposes that Doc lands the DeLorean on top of Biff's car to stop him, Doc comments on how fragile it is compared to Biff's car; "It'd rip through us like tin foil." Part III shows that Doc is not exaggerating; the DeLorean is struck by an oncoming train and is completely obliterated.
  • While the first scene is more or less a direct recreation of the first film's ending, one difference is that Doc slightly hesitates in telling Marty that he and Jennifer are fine in the future, while that dialogue was delivered straight originally. Doc's hesitation hints at the somewhat dodgy situation the young couple find themselves in 2015.
  • Relatedly, Marty (disguised as his son) meets Old Biff, who insults his father "Marty McFly Sr.? The man who took his life and flushed it completely down the toilet." Marty is confused by that statement, and basically forgets about it when Griff shows up. While Marty doesn't, the audience soon finds out how. Though in Part III, Doc accidentally reveals to Marty that his future is a mess, but couldn't say more.
  • When loading an unconscious Jennifer on to the DeLorean, Doc, having decided to destroy the DeLorean, laments that he'll never get to see his favorite time period, the Old West. He then says he'll probably start exploring another of the universe's great mysteries... women. Guess what happens in the third movie.
  • When Marty heads to the Hill Valley Courthouse Square of 1985-A and sees the full extent of Biff's alterations to the timeline, Sammy Hagar's "I Can't Drive 55" plays as a dark counterpart to the "Mister Sandman" Sequence.
  • When first arriving in 2015, Doc notes that the weather report is accurate to the very second and wishes the postal service could be just the same. Sure enough at the end of the film, Western Union shows up to deliver Marty a message from 1885 right right after Doc disappears as specified in his letter.
• Freeze-Frame Bonus:
  • Many of the examples listed under "foreshadowing" count, but there's a subtle one in that when Marty wears clothes exactly like his future son, he has a red shirt on under the jacket, but when his son gets to the Cafe 80s, he has a white shirt. None of the characters in-universe seem to notice this discrepancy when they switch. Marty Jr. also has different colored eyes, proving he did get something from his mother.
  • Griff, though he looks exactly like a young Biff, also has blue eyes instead of brown.
  • At the beginning of the film, when Doc backs the DeLorean out of the driveway and stops to shift out of reverse, we see a shot of the license plate which no longer reads "OUTATIME" as it did at the beginning of the first film. In this shot, the plate has changed to a chrome barcode on top of an orange background. Like all barcodes, this one has numbers below the bars which read "1011000." This binary number translated to decimal is "88" (as in "88 miles per hour"). This license plate is also briefly visible at the very end of the first film (but is out of focus) and is is shown spinning on one corner after the DeLorean is destroyed by a train at the end of the third film.
  • Many of the headlines of the 2015 USA Today newspaper count, such as "Queen Diana Visits Washington" and "Thumb Bandits Strike".
  • If you pay close attention during the Biff Tannen Museum video, you can see the Sports Almanac visibly tucked in 1958 Biff's jacket pocket. Doc later points it out to Marty when he shows him that day's newspaper and its accompanying banner photograph.
• Future Imperfect: Deliberately invoked with the '80s-themed diner; the aesthetic mashes together major icons of '80s pop culture like Max Headroom and Ronald Reagan.
• Future Loser: Marty in the version of 2015 seen here (which ultimately doesn't end up happening thanks to events of Part III), due to getting into a car accident with a Rolls-Royce soon after returning home from the events of the first movie (the next day, in fact!). He wound up busting his hand, ending his aspirations of a music career, and was forced to pay for damages. By 2015, Marty is stuck in a dead-end job, unhappily married to Jennifer (who, according to Lorraine, married him out of pity, with their wedding taking place in a cheap chapel), and gets fired when his bosses monitor his calls and learn of his involvement in an illegal transaction. 1985 Marty never finds out the full details about this, only learning from Doc in Part III that he's involved in some kind of accident that messes up his future; it's Jennifer who witnesses this when she's brought to their house after being mistaken for the 2015 one. She's dismayed to see how much her life together with Marty has not gone as she'd hoped it would.
• Future Me Scares Me:
  • Jennifer unwittingly runs into her future self and passes out in shock after gasping "I'm old!" Also, Old Biff meets his teenage self. Even funnier, Jennifer's future self happens to pass out in shock gasping, "I'm young!"
  • Old Biff is pretty scary, given that that version of Biff has just as much of a temper as young Biff, with bitterness that's been marinating for decades added in, and actual intelligence to replace his thuggishness.
  • Jennifer also has a similar reaction to the sight of her future boyfriend/husband, Marty — he is unbelievably different than the guy that she's in love with in 1985. Marty himself never sees his future self, but he learns enough in Part III to avert the accident that sent him down that path.
• Future Slang: It's actually weird how you wouldn't be surprised if actual teens from the 2010s actually used many of the words, with the rise of nonsense words and terms that have come to existence in the decade.
  Spike: What's wrong, McFly? You got no scrote?
  
  Whitey: Hey McFly, you bojo, those boards don't work on water!
  
  Officer Foley: Hilldale, nothing but a breeding ground for tranks, lobos, and zipheads.
  
  Marty Jr.: Don't drive tranq'd, low-res scuzzball!
  
  [in Craig Shaw Gardner's Novelization]
  Marlene: No, I don't want to, so nump off!
• Future Spandex: 2015 fashion tends toward the "unbelievably silly" version of this trope. Marty does a Double Take seeing one girl wearing spandex leave the Cafe 80s.
• Futuristic Superhighway: The movie begins with Doc, Marty, and Jennifer arriving in the year 2015 inadvertently flying against traffic on a highway specifically designed for Flying Cars.
• Gangland Drive-By: In 1985-A, a truckload of gang members shoot up Strickland's house. Strickland responds with a shotgun.
  Strickland: Eat lead, SLACKERS!
• Genre Blindness:
  • In retrospect, 1985-A Biff should've pulled out his pistol and shot Marty the minute he mentioned the Almanac instead of going through a Just Between You and Me.
  • Marty and Doc didn't expect that 2015 Biff would also warn his younger self about the Partners in Time and what to do if anyone matching their description showed up knowing about the book. Justified, as Doc and Marty are used to dealing with the younger, dimwitted Biff and not one who's Older and Wiser.
• Gilligan Cut: Marty needs to get some Fifties clothes:
  Doc: Something inconspicuous!
  [cuts to Marty outside Biff's house, wearing a not-so-inconspicuous leather jacket, hat, and shades, resembling the Blues Brothers]
• God Test: Biff challenges his future self to prove that the Gray's Sports Almanac has the results of every sporting event in the next 50 years. So old Biff plays a sports broadcast and demonstrates it.
• Graceful Loser: The Western Union man who delivers Doc’s letter to Marty comments that the Post Office had a bet over whether or not Marty would be there, which he admits that he lost with a laugh.
• Groin Attack:
  • When the gang is intimidating Marty Jr.
    Spike: What's wrong, McFly? [shoves a long and razor sharp nail between Marty Jr's trousers] Ya got no scrote!?!?
  • Marty tries to pull the "Hey, what's that?!" move on Griff, who intercepts his fist instead. He only gets away by kicking Griff's steel balls.
  • Biff unknowingly throws a couple of oil cans onto Marty's midsection (who is hidden in the back seat of Biff's car).
  • 1985-A Strickland accuses Marty of stealing his newspapers and gives him until the count of three to get off the porch with his nuts intact.
• Guess Who I'm Marrying?: We don't actually see when Lorraine-A tells her kids who she is going to marry in 1973-A, but the reaction of the Marty from our timeline fits the bill.
• Half-Identical Twins: Marty Jr. and Marlene, possibly. Some scripts have both children mentioned as being 17, and both were played by Michael J. Fox — so they're commonly believed to be fraternal twins.
• Hand Wave: To avoid Christopher Lloyd having to put on the "1985 Doc" make-up for the two sequels, an in-universe explanation was provided for a slightly younger-looking Doc: He had extensive plastic surgery and organ replacements in 2015. They also replaced his spleen and colon, and extended his life by "thirty or forty years" — also meaning he can have a long and happy life with Clara after Part III.
• He Knows Too Much: Old Biff gets the idea to back to the past to give his 1955 self the Gray's Sports Almanac, so he'll be rich in the future. He also tells him that either a kid (Marty) or an old man (Doc) will come around asking about that book, and to kill them if they do so. Indeed, Present Biff-A tries to shoot Marty down in his own office after he finishes his exposition, and Marty barely escapes with his life.
• Help Yourself in the Future: Inverted: Marty has to stop Biff's gang from attacking his first film's counterpart during "Johnny B. Goode".
• Heroic BSoD:
  • Doc at the end, when all of the implications of Marty's return from the future hit him. He faints.
  • Marty also has one when he finds out that his dad was murdered in the alternate timeline — and that it's basically his fault, because Biff stole the almanac that Marty bought in 2015 after finding out about the time machine.
• Hesitation Equals Dishonesty: At the end of the first film, Marty asks Doc if he and Jennifer "become assholes in the future." Doc straightaway says no. When the scene was reshot for the start of the second film, Doc hesitates before answering their question. This was due to there being no plans for a sequel when the first film was shot.
• High-School Sweethearts:
  • The main character, Marty, has this relationship with his girlfriend, Jennifer — we see them married with two kids in the future. But in this first timeline, the marriage isn't very happy.
  • The bad timeline has a newsreel claiming Biff and Lorraine were this, when they were clearly anything but.
• Historical Villain Downgrade: It's implied 1985-A Biff has done this with his ancestor Buford (based on the Biff Tannen Museum video and the downplaying of Buford's nickname "Mad Dog"). Part III will subsequently confirm this.
• Hoist by His Own Petard: When future Biff gets back to 2015 from the past, he hits himself in the chest with his cane while getting out of the DeLorean, and apparently dies. This was because in the bad future that was created after Biff gave himself the Sports Almanac, he gets shot by Lorraine sometime in the 1990s; Biff's collapse was supposed to be the beginning of the altered past causing him to fade out of existence.
• Hold Your Hippogriffs:
  • "Hey, McFly, your shoe's unvelcked!" (loose — think "Velcro")!
  • Also, the Doc saying Griff has "a few short circuits in his bionic implants".
• Hologram: Marty is attacked by a holographic shark advertising Jaws 19 playing at a holographic movie house in Hill Valley of 2015.
• How the Mighty Have Fallen: Back in 1955, Lorraine was a headstrong spitfire who swore she'd never ever marry Biff even if he had a million dollars. In 1985-A, Lorraine has been reduced to a battered, defeated trophy wife forcefully married to Biff, broken to the point where she can only resign to his whims and believe his cruel treatment is her fault.
• Hubcap Hovercraft: The DeLorean, which is shown being capable of hovering since the ending of the first movie (following up Doc's return from the future) is the Trope Codifier. It turns out that, by 2015, all cars can undergo a "hover conversion" like this.
• Hypocrite: 1955 Strickland calls young Biff out for having liquor on his breath then confiscates his girly mag. Later, in his office, he makes himself an Irish coffee and has a look through the magazine himself. Pretty justified, since he's an adult with legal access to those things, while Biff is still a teenager who's not yet old enough to drink or buy porn.
• I Coulda Been a Contender!: Marty's Bad Future includes a car accident which resulted in a hand injury that left him unable to play the guitar.
• Identical Grandson: Played Straight. Griff looks a lot like how Biff did back in 1955.
• Ignored Epiphany: In the novelization, there's a scene where Old Biff is sitting in the Cafe 80's and realizes how much of a jerk he was and that he wasted his life thanks to how he acted. Of course that all goes out the window once he gets his hands on the Sports Almanac and the time machine.
• I Hate Past Me: Old Biff isn't all that thrilled to be giving anything to the idiotic, amoral, young Biff, but is willing to do so because then he'll be rich in the future.
  Young Biff: Now, why don't you make like a tree and get outta here?
  Old Biff: (Dope Slaps his younger self) It's LEAVE, you idiot! Make like a tree and leave! You sound like a damn fool when you say it wrong!
• I Have to Wash My Hair: Said by Lorraine in 1955 when Biff "invites" her to the dance with him in an attempt to get him to stop harassing her.
• Immediate Sequel: Picking up from the last movie's Sequel Hook, the opening scenes of Back to the Future Part II dive right into the new storyline of Doc Brown whisking Marty and Jennifer thirty years into the future to sort out a problem with their kids — unknowingly setting off a line of Disaster Dominoes that will keep causing problems for the trio for the next two movies.
• Imperial Stormtrooper Marksmanship Academy:
  • A convertible full of gangsters emptying their rifles at Strickland's home, reducing it to a two-story block of Swiss cheese, and they manage to completely miss both Strickland and a cowering Marty.
  • Biff-A firing at Marty in his suite has tastes of this as well (he is using a pistol with a barrel shorter than the cylinder, so this may be justified). He was also drinking, so that may have also influenced his aim.
• Improvised Weapon:
  • Lorraine communicates her distaste for Biff by clocking him with the box carrying her prom dress before running away with her friend as Biff shouts after her that she'll be his wife one day. That must be some hefty dress.
  • When confronted by Biff in 1985-A, Marty grabs a matchbox tray that conveniently has sharp metal triangles facing outwards along its edge and throws it at Biff like a Frisbee, forcing him to duck as it embeds itself into the back of his chair.
  • The Frisbee attack is later recalled in the third movie, with Marty throwing a pie tin at Biff's ancestor, Buford. (With the words "Frisbee Pies" on it, no less.)
• Incoming Ham: Marty's future boss Mr. Fujitsu makes the most of his short screentime by popping up on a surprise video call and announcing himself with a stentorian "McFLY!!"
• Inconsistent Dub: The Latin-American Spanish dub of this film, along with the sequel, was quite infamous in its time not only for replacing the whole cast, but also for ignoring the terminology used from the Mexican-made dub, as the second and third films were dubbed in the States in Los Angeles instead. Just to begin with, the Latin American name of the movie went from Volver al futuro (literal translation) to Regreso al futuro ("Return to the Future"), and the list of terms changed would be too large to mention here.
• Incredibly Obvious Tail: Done for laughs. Doc tells Marty to be inconspicuous when trailing Biff; Gilligan Cut to Marty wearing a black leather jacket and a fedora as he follows Biff (who, true to the trope, doesn't realize he's being followed until Marty gets right up in his face).
• Indy Hat Roll: Marty McFly makes use of the maneuver. At the school dance in 1955, Marty dives under a table to escape Biff's gang, leaving just enough time to grab his own Indy-esque hat before trouble arrives.
• In Spite of a Nail: The only things that have been confirmed not to have been changed in the 1985-A timeline are that Michael Jackson still becomes a famous pop star, A Fistful of Dollars still gets made, the Wounded Knee Occupation still takes place, Red is still a homeless bum and Lorraine's brother Joey still turns out to be a jailbird.
• Insult to Rocks: When talking about 1985-A.
  Marty: It's like we're in hell, or something.
  Doc: No, this is Hill Valley, although I can't imagine hell being much worse!
• Invincible Classic Car: Lampshaded:
  Marty: Let's land on him, we'll cripple his car.
  Doc: Marty, he's in a '46 Ford; we're in a DeLorean. He'd rip through us like we were tinfoil.
• Interquel: Doc and Marty travel to 1955 in the hours leading up to the "Enchantment Under the Sea" Dance and lightning storm in the first film.
• I Own This Town: A filthy rich Biff has corrupted Hell Valley and is now its overlord.
  Biff-A: Kid, I own the police!
• I Remember Because...: In a deleted scene, the historical preservation society member says that he remembers the day lightning struck the clock tower because it was also the same day that Biff Tannen stiffed him out of a repair bill for cleaning a truckload of manure out of Biff's car.
• I Remember It Like It Was Yesterday: Marty, when he returns to 1955. Doc mentions that he was there yesterday. From the time Marty left 1955 at the climax of Part I (arriving on October 26, 1985, 1:24AM), to when he traveled to 2015 (a little after 10:30AM on October 26, 1985), the time he spent 2015 (October 21, 2015, 4:29PM to 7:28PM), and from when he arrives in 1985-A (October 26, 1985 9:00PM) to the time he returns with Doc to 1955 in the middle of Part II (leaving 1985-A at around October 27, 1985, 2:00AM), is from Marty's perspective about 17 hours. And of course, another Marty had been there yesterday. And about five more days before that.
• I Resemble That Remark!:
  2015 Biff: Just get in the car, butthead.
  1955 Biff: Who're you callin' butthead, butthead?!
• Irony: While 1985 Doc is warning Marty not to be spotted by his other self, Doc gets spotted by his other self. The way their awkward conversation ends only adds to the irony.
  1955 Doc: Well it was nice talking to you. Maybe one day, we'll run into each other again in the future!
  1985 Doc: [to himself] Or in the past...
• It Only Works Once: To prevent Jennifer from asking too many questions about her future, Doc uses a sleep-inducing device to tranquilize her. Unfortunately, this causes a minor crimp in his plan to have Marty take his son's place at a meeting with Griff as the inducer didn't have enough power left to knock Marty Jr. out for a full hour, resulting in him showing up.
• It's All My Fault: Said by Marty when he realizes Biff stole the almanac.
• It's Personal: Marty sees an ad with the tagline "This time it's really really personal!"
• It's Probably Nothing: When Marty and Doc speed over to Marty's future home to retrieve Jennifer, Doc notices a cab in his rearview display, thinking it might be following them, but dismisses it as nothing. Turns out it was the cab transporting 2015 Biff and it really was following them.
• I Want My Jetpack: Hoverboards, holographic movie posters, auto-adjusting clothes, ubiquitous robots, dehydrated pizza, weather reports accurate to the minute, commercially available fusion reactors small enough to power car, flying cars in such numbers to cause traffic jams. October 21, 2015 came and went and none of these things were available.
• Jaded Washout: 2015 Marty Sr. is a sour salaryman who gave up his guitar dreams when he injured his hand and was targeted with a lawsuit after a car accident. Driven home by him busting out his guitar after being fired and strumming a few chords — he's not rock-star level, but he plays decently. It's likely he gave up more out of lack of confidence than the hand being a serious problem.
• Japan Takes Over the World: 2015 was partly based on the assumption that the Japanese economy would have overtaken the US one by the early 21st Century.
• Jerkass Has a Point: Fujitsu was in the right to fire 2015 Marty — while the latter knew that going into Needles's illegal scam was wrong, he went along with it.
• Just Between You and Me: Biff-A tells Marty the circumstances of how he received the Almanac, then pulls out a pistol mentioning that his older self told him to kill anyone who ever asked about it.
• Just Keep Driving: When Doc takes Marty to the future for the first time, no one seems to notice the Delorean that appeared out of nowhere in the middle of a busy "highway" during rush hour traffic. Though they do swerve, you'd think that a car that appears out of nowhere would create more of a stir.
• Karma Houdini: It's left ambiguous whether Needles gets reprimanded for deceiving Marty into performing the illegal scan in 2015.
• Kavorka Man: The hotel's museum includes a slideshow of Biff's past conquests — which include the biggest pin-up gals of the day, each with Biff making sleazy Night at the Roxbury faces to the camera.
• Kick Them While They Are Down: After Marty is knocked over in 1955, Biff takes the sports almanac back. He then kicks Marty in the stomach twice, the second time saying "This one's for my car!" Marty is lying on the ground, but he is still conscious.
• Kill It with Fire: How the threat of the Gray's Sports Almanac is finally dealt with once and for all.
• A Lady on Each Arm: In the alternate timeline, the wealthy and corrupt Biff Tannen (who, by the way, forced Lorraine to marry him after he murdered her husband) is seen in his private quarters lounging in a hot tub with his arms wrapped around two ladies, watching a Clint Eastwood film.
• Large Ham: Griff Tannen. Loud, obnoxious, and rarely calms down. Just like his grandfather and ancestor.
• Latex Perfection: Subverted when Doc Brown details the rejuvenation treatments he got in the future and pulls off his latex mask to reveal his new appearance. And he looks almost exactly the same underneath, just a little bit younger. It's a bit of a meta-joke — 1985 Doc in Part I was played by Christopher Lloyd in aging makeup, but he didn't look much different from 1955 Doc, played by Lloyd without makeup. Now that both "versions" of Doc looked the same, they didn't have to do the makeup anymore, a feature they kept for Part III (just in time for Doc to pick up a Love Interest).
• Law of Time Travel Coincidences: Discussed when Doc finds out that Old Biff travelled to the same day, November 12, 1955, that Marty departed from in the first film. It's also the day of the Enchantment Under the Sea Dance where Marty's parents fell in love and the historic thunderstorm that stopped the town clock. Doc ponders if the date could have some "cosmic significance" but shrugs it off as an incredible coincidence.
• Like Father, Like Son: Considering the fact that Griff seems to anticipate Marty's reaction to being called "Chicken" when he thinks he is Marty Jr., it appears that Marty's son has the same issue with the name as he does.
• Lightning Can Do Anything: A lightning strike sends the DeLorean — with Doc inside — back to 1885, by causing the car to spin so fast it hits 88mph. This is why the fire trails are in a circular nine-esque shape rather than the traditional parallel lines.
• Make Wrong What Once Went Right: Biff goes back in time to make his younger self rich, which eventually turns the city into a hellhole. The only person who benefitted in any way is Biff, who now owns everything. Plus, as explained by the film's director, even Biff lives to regret it: the reason why he's clutching his chest as he gets out of the DeLorean in 2015 is that he was so awful that Lorraine shot him dead sometime in the 90s, so he's no longer alive in that timeline, which is now in the process of changing the world around him into a dystopian 2015.
• Male Gaze:
  • While trying to keep track of Marty, Jr. through some Star Wars-esque binoculars, Doc Brown's line of vision constantly shifts to the very busty women that passed by him. Although this may just be the auto focus feature of the binoculars, the trope still applies on a meta level.
  • Marty does a double take as a rather attractive woman exits the Cafe 80s as he is entering.
  • He also keeps looking down at his mother's enhanced boobs in 1985-A, although this is more shock and disbelief than titillation.
• Manly Tears: Marty when he finds his father's grave in 1985-A. Thankfully things turn out differently in the end.
• Married in the Future: Doc takes Marty and Jennifer into the future where she sees their future home and kids, but everything else sucks. In Part III, however, Marty manages to avert the event that led to that timeline.
• Maybe Magic, Maybe Mundane: Upon learning Old Biff chose November 12, 1955 to return, Doc wonders if that day has some cosmic significance or it's just a coincidence.
• Mean Boss: Ito T. "Jitz" Fujitsu. In fairness, he had good reason for firing Marty Sr., but he made no indication of coming down as hard on Needles (who briefly smirked before hanging up, indicating he won't be in trouble at all).
• Meaningful Background Event: Marty is fretting about not knowing where Biff is while we can hear in the background his future mother being assaulted by Biff as in Part I. It gets louder until Marty hears it.
• Meaningful Echo: The confrontation between Marty and Biff in the tunnel, with Marty trying to use his hover-board to outrun Biff's car, then being pulled up by Doc with a kite string just as Biff gets to him, causing Biff to crash into a manure truck, is practically a repeat of the confrontation between Marty and Griff's gang in 2015.
• The Men in Black: Played with. After lightning strikes the DeLorean and traps the Doc in 1885, a car pulls up next to where Marty is standing and a sinister man steps out and addresses him by name. He's actually a courier from Western Union delivering a message from the Doc.
• Missed Him by That Much: When Marty arrives in 1955 and sneaks into 1955 Biff's car, he doesn't know that 2015 Biff is hiding from behind a tree, and lucky that 2015 Biff turned his head away at the point when he would have seen Marty.
• "Mister Sandman" Sequence: Like in the first movie, "Mr Sandman" is played when Marty tails young Biff to retrieve the Gray's Sports Almanac, though it's shorter than Marty's first walk into 1955 Hill Valley and doesn't have the same emphasis on 1950s culture.
• Mock Headroom: When Marty visits the Cafe 80s, his server is a roaming TV monitor with an avatar of Ronald Reagan, glitching and speaking in warped tones like Max Headroom. He's joined (and naturally argues with) an avatar of the Ayatollah Khomeni. Another television shows an avatar of Michael Jackson.
• Money to Burn: Biff's image is depicted on the front of his casino doing this.
• Mood Whiplash: Going from the bright, lively Hill Valley of 2015 to the dark, terrifying "Hell" Valley of 1985-A.
• Mordor: 1985-A is a smoggy futuristic Mordor. Marty's neighborhood looks more or less the same (only shabbier, with the Lyon Estates lion statues being defaced with graffiti, and a pack of stray dogs roaming around), but smokestacks are visible everywhere else, including the graveyard.
• More Dakka: The police in 1985-A keep what tenuous order they can by being armed with automatic rifles and patrolling in an Armored Personnel Carrier.
• Mundane Utility: The DeLorean is at its most useful for purposes other than time travel in this movie after Doc had a hover conversion job done on it. Its ability to fly comes in most useful in time periods where there are no other flying cars, such as rescuing Marty from nearly meeting his father's fate in 1985-A, or in their effort to swipe the Almanac from Biff in 1955.
• Murder the Hypotenuse: the Biff Tannen of the alternate 1985 murdered George McFly in 1973 and married Lorraine shortly afterwards, paying Hill Valley police to look the other way.
• My God, What Have I Done?: Marty after realizing that the entire future has changed for the worse due to his idea of using the Almanac for selfish purposes.
• Nature vs. Technology: As Technology Marches On, the society of the future seems to have weather control that is more reliable than the post office. Word of St. Paul in additional materials hints that the future depicted is a nuclear-powered one by the very common availability of Mr. Fusion. No matter how impressed Marty and Doc Brown are about it though, there are two police officers that discuss among themselves that it is a Crapsaccharine World.
• Never My Fault:
  • When Griff and his gang are arrested as a result of trying to beat up who they believe to be Marty Junior for not agreeing to join them for a theft, Griff says he was framed.
  • Future Marty tries to talk his way out of being fired for his illegal operation by claiming it was Needles' plan, which is technically true, but, as Fujitsu points out, Marty still cooperated knowing it was illegal.
• Never the Selves Shall Meet: Doc explicitly warns Marty to be careful in following Biff to get the Sports Almanac back that he must not be noticed or interact with his previous self.
• Newspaper Dating: Marty performs it again when in 1985-A. Lampshaded by Strickland: "So you're the son-of-a-bitch who keeps stealing my newspapers!"
• The New '10s: The first act of the movie takes place in 2015.
• Nice Job Breaking It, Hero:
  • Most everything that happens in this film (and by extension the third film) is Marty's fault. His scheme to use the almanac to make himself rich is what kicks off the main plot.
  • Marty manages to recover the almanac, but when confronted by Biff who taunts him about being chicken, Marty goes into his Nobody Calls Me "Chicken"! mode, which winds up getting him found out he took the almanac, which gets taken away again.
• Nice Job Fixing It, Villain: Had it not been for 1985-A Biff's boasting about how and when he acquired the Almanac, neither Marty or Doc would've known at what point in the time line to properly intercept 2015 Biff's efforts to change the past.
• Nobody Calls Me "Chicken"!: Marty is the Trope Namer. His biggest Berserk Button is being called a chicken, and thus reacts sternly in front of the one who tells him so. Unfortunately, in some cases this makes his situation even worse.
• No Celebrities Were Harmed:
  • 1985-A Lorraine was modeled after various female televangelists of the 80s, particularly Tammy Faye Meissner (aka Tammy Faye Bakker).
  • By that same token, 1985-A Biff's looks were modeled on Donald Trump, which became a big talking point around the movie after he became president in 2016 and Bob Gale brought it up. Other things 1985-A Biff has and does also make this more obvious, like paintings he has of himself in his hotel and the fact that he's a billionaire business tycoon with his own hotel named after himself.
• No Escape but Down: Biff corners Marty at the edge of a roof and Marty jumps. Something of a Suicidal "Gotcha!" since he lands on the roof of the Delorean hidden from Biff's view, only a few feet below.
• No Doubt the Years Have Changed Me: Parodied with Doc in 2015. Played straight with Lorraine in 1985-A, who looks radically different from her 1973-A self, when she was shown marrying Biff.
• No-Paper Future: Averted, at least in the case of "YOU'RE FIRED!!!" faxes and "dust-repellent paper". Cash is also still in use, although most people don't use it and use their thumb to pay.
• Non Sequitur Causality: The 1985-A newspaper that shows that Doc Brown has been committed also says Richard Nixon is running for a fifth term and The Vietnam War is still ongoing. All because Biff Tannen made a fortune on sports gambling!
• No-Sell: In 2015, Marty McFly tries to use the "Hey, what's that?!" move on Griff Tannen, Biff's grandson, who simply intercepts his fist thanks to bionic implants. Marty only escapes by kicking him in the groin.
• Notably Quick Deliberation: It's mentioned in passing that Marty's son was tried, convicted and sentenced within a mere two hours of his arrest. Doc Brown explains that the criminal justice system is much more efficient since the abolition of lawyers.
• Not Hyperbole: When Doc and Marty go back to November 12, 1955, Marty says "It's like I was just here yesterday.", to which Doc says that he was there yesterday. From the time Marty left 1955 at the climax of Part I (arriving on October 26, 1985, 1:24AM), to the time he returns with Doc to 1955 in the middle of Part II (leaving 1985-A at around October 27, 1985, 2:00AM), is a real-time passage of about 24 hours, though from Marty's perspective, since he spent three hours in 2015, only to travel back to about 10 hours after he left 1985, it's a bit less than 24 hours for him. Of course, from the perspective in 1955, another Marty had been there yesterday on November 11, and about five more days before that.
• Not So Great Escape: Marty finds himself trapped in Strickland's office while trying to retrieve the almanac and has to desperately hide beneath the desk and in other spots to avoid being discovered, including getting his hand crushed by Strickland's chair.
• Not the First Victim: In 1985-A, while threatening Marty, Biff-A indirectly reveals that he's the one who killed Marty's father in this timeline.
  Biff: I suppose it's poetic justice. Two McFlys... with the same gun.

Tropes O-Z

• Obliquely Obfuscated Occupation: In the future, we're never told what Marty does at CusCo, or what "the plant" actually produces. His conspiracy with Needles (embezzlement? insider trading?) is ambiguous and left to the imagination, though the dialogue with Needles saying their plan would, "Solve all of [2015 Marty's] financial problems" implies some sort of money transfer scheme. Fujitzu being able to immediately detect Marty scanning his card for Needles to use for it implies it was at least partially done through their company's network.
• Off to Boarding School: The Marty of 1985-A was sent off by Biff to a boarding school in Switzerland at some unknown point prior to "our" Marty's arrival.
• Oh, Crap!:
  • This is Jennifer's reaction to pretty much the whole time she is trapped in her future home, trying not to be seen. Her biggest one comes from coming face-to-face with her 47-year-old self, causing both of them to faint.
  • When Marty learns that "Griff" is actually Griff Tannen, Biff's grandson.
  • Griff, already as imposing as his grandfather was at his age, starts to get bigger as his cybernetics kick in. Marty looks a little worried.
  • Marty's horror-struck reaction when he sees not only what has happened to his home in the alternate timeline, but perhaps even worse when he realizes that Biff has married his mother.
  • Marty, when he realizes Biff-A is going to shoot him for knowing too much. Seconds later, Biff-A has a similar reaction upon seeing Marty standing on the flying DeLorean.
  • Doc, when he warns Marty not to let his other self see him. Lo and behold, the 1955 version of Doc sees him from behind and calls out to him. 1985 Doc quickly takes measures not to show his face to him as he has an awkward conversation with him.
• "Oh, Crap!" Smile: when Marty McFly first faces Griff Tannen and his gang in 2015:
  Griff: What's wrong, McFly, chicken?
  (Data plays a chicken clucking sound-effect)
  Marty: (turning around) What did you call me, Griff?
  Griff: Chicken, McFly!
  Marty: Nobody calls me...
  (Griff whips out a baseball bat)
  Marty: (chuckles sheepishly) ...chicken.
• Older Is Better: In a bit of Shown Their Work, Marty suggests that Doc ram the DeLorean into Biff's car to disable it. Doc dismisses the idea, as the all steel construction of a 40's car would rip apart a modern fiberglass shell DeLorean.
• Ominous Multiple Screens: A comedic version occurs in the 2015 segment, when Marty's son comes home from school and watches a half dozen TV channels at one time. Then it turns serious when they all begin flashing messages that announce that Marty was fired.
• Oppressive States of America: Besides Biff running Hill Valley of 1985-A like his own personal kingdom, there's news of Richard Nixon going on his fifth term as President of the United States (meaning Biff's influence got the 22nd Amendment overturned), and (in the novelization) the Vietnam War still being waged in the 1980s.
• Overly Stereotypical Disguise: Marty falls into this trap with the "something inconspicuous" outfit he bought with Doc's money. The leather jacket and Sunglasses at Night would've been conspicuous enough, but then he tops it off with a nice trilby hat, which was not considered casual headwear and normally only worn with a suit in the '50s.
• Outdated Outfit: In 1985-A, Biff and his gang (still together since 1955) seem more in line with The '70s than The '80s. This is partly because they're modeled after Elvis Presley and his "Memphis Mafia" in the last years of his life.
• Pac Man Fever: Wild Gunman being showcased at the Cafe 80s is perfectly fine, as Nintendo put out an arcade Playchoice-10 version, but the version shown doesn't exist in reality; none of its game modes allow you to face off against four of the game's outlaws simultaneously, and it doesn't have a "Crack Shot!!" bonus.
• Paid Harem: Biff-A's got buxom blondes in the hot tub in 1985-A.
• "Pan from the Sky" Beginning: After the opening recap of the end of Part I, we then cut to a shot through a cloudy sky as the opening credits play to Alan Silvestri's title theme before panning down to a sky freeway as the Delorean arrives in 2015.
• Papa Wolf: When Marty sneaks into what was once his bedroom after returning to 1985-A, he learns the hard way that an African-American family lives there now. Sure enough, when the father catches an understandably shocked Marty in the act, he resorts to using a baseball bat to protect his family, forcing Marty to escape unharmed.
• Paranormal Gambling Advantage: Biff steals Doc Brown's DeLorean and delivers a sports almanac from the future to his younger self, creating a new timeline where Biff becomes an all-powerful billionaire. Also counts as Time Travel for Fun and Profit. Marty admits he intended to do something similar.
• Partly Cloudy with a Chance of Death: Played with at the end, with Marty seemingly stranded forever in 1955 during a thunderstorm.
• Percussive Maintenance: When they are about to go back to 1955, the time display of the DeLorean flashes between 1885 and 1955. Doc punching it twice removes the glitch, but Doc remarks he'll have to fix that thing properly. Notably this only fixes the problem a total of once. When he accidentally switches on the Time Circuit again at the end of the movie it glitches to 1885 again and this time Doc doesn't notice to whack it again which sends him back to that time when the lightning hits the car.
• Pet the Dog: A very minor one, but when Marty does a Verbal Backspace and notes to Biff that November 12, 1955 was when the famous Hill Valley Lightning Storm hit (which was also the day he traveled back to 1985, a fact he almost revealed to Biff), Biff sincerely compliments him for knowing his history, complete with a "very good." For Biff, that's a lot.
• Pink Is Erotic: In 1985-A, the sleazy and perverted Biff seduces women in a pink, purple, and red home, owns pink towels, and other pink decorations.
• Plot-Triggering Book: Old-Biff overhears Doc Brown telling Marty to throw away "Gray's Sports Almanac" in 2015 before they return to 1985 since he didn't invent Time Travel so they can gamble. As Marty and Doc Brown rush to get Jennifer out of her and Marty's future home before she sees her future self, old-Biff "borrows" the Delorean-time machine. When the trio gets back to 1985, Hill Valley has been turned into a dystopia where the town is one large slum and Biff is a billionaire casino owner, as Doc Brown and Marty discovered that old-Biff went back to 1955 to give his teen-aged self the book so that he could be rich and powerful in the future.
• Police Are Useless: In 1985-A; somewhat justified as Biff has used his wealth to take control of Hill Valley, where the police department is corrupt and answers mostly to Biff in a city that under his watch has become an almost literal hellhole. Averted with the 2015 police officers.
• Power Fist: Old Biff in 2015 has one of these adorning the top of his cane, which he uses to clobber Marty (masquerading as his son) over the head. The top of the cane is left behind in the car when Old Biff returns to 2015 from 1955, and Marty recognizes it when Doc shows it to him in the 1985-A timeline.
• Pre-emptive Declaration: Doc and Marty watch the newspaper article about Marty Jr.'s arrest, headlined, "Youth Jailed: Martin McFly Jr. Arrested For Theft" change to the headline, "Gang Jailed: Hoverboard Rampage Destroys Courthouse. Gang Leader: 'I WAS FRAMED'", under a photo of Griff being taken to a police car in handcuffs. Doc looks up and sees Griff being perp-walked down the courthouse steps to a police car in handcuffs as a USA Today camera drone descends from the sky. Griff shouts, "I WAS FRAMED!" at which point the camera snaps his picture.
• Present-Day Past: In 1985-A, when Marty finds out that his house is occupied by another family, a poster for Dirty Dancing can be seen on the wall, which wasn't released until 1987.
• Prince Charming Wannabe: Again, Biff with Lorraine in 1955.
• Privately Owned Society: Biff owns Hill Valley in the alternate 1985 including the police, who may or may not just be on the take.
• Properly Paranoid: When Marty confronts 1985-A Biff about the Sports Almanac and the exact details of how, where and, above all, when he got it, Biff decides to cooperate. He soon reveals the reason why he played along as he pulls out a gun and attempt to kill him.
  1985-A Biff: [The old man] said someday, a "crazy, wild-eyed scientist or a kid" may show up asking about that book. And if that ever happens... Funny... I never thought it would be you.
• Punch Catch: Biff's grandson Griff catches Marty's hand when he tries to do the trick that worked in the first movie — saying "Hey, what's that?" and then punching Biff when he turns to look. Marty settles for kicking Griff in the nuts instead.
• Punctuated! For! Emphasis!:
  • "Read. My. Fax!"
  • "Gray's. Sports. Almanac!"
• Put on a Prison Bus: Griff Tannen and his Gang of Bullies are last seen being arrested after their chase against Marty ends with them crashing their hoverboards into the courthouse. The newspaper confirms their arrest.
• Ransacked Room: In 1985-A, Doc and Marty take shelter at Doc's home in this timeline, which has been ransacked after his counterpart was put into a mental institution.
• Reading Foreign Signs Out Loud: In the French dub, when future Marty is fired and every fax around his house begin printing "You are fired" messages, this is accompanied by numerous digitized voices cheerfully reading the translation for each of them.
• Reality-Breaking Paradox:
  • Doc Brown says that the paradox of Jennifer meeting her future self could cause a paradox that destroys the universe. "Granted, that's a worst-case scenario. The effects might be limited to our own galaxy." The novelization gives a little more detail: it's less them possibly meeting and more the possible consequences of the meeting, like say, if the younger Jennifer panicked and ended up causing her past self an injury that her future self never had. Or say, if she tripped and fell down and cracked her head open, making her alive and dead at the same time. In the end, all that happens is that she simply passes out from the shock, which Doc had also admitted was a possibility.
  • When there is a meeting of selves (in the past, no less) the consequences are less severe — a Timeline-Altering MacGuffin leads to a Bad Present that Doc and Marty are forced to prevent.
• Remember the New Guy?: When Needles appears in 2015, the film makes it clear that he's an older version of someone Jennifer knows from 1985, but we've never seen him before. And it's not until the end of the next movie that we get to see the teenage version of Needles that was already known to both Marty and Jennifer.
• Repetitive Audio Glitch: The computerised-Reagan waiter at the Cafe 80s does this, presumably in imitation of Max Headroom.
  Reagan: Welcome to the Cafe 80s! Where it's always morning in America, even in the afternoo-noo-noon!
• Request for Privacy: In Alternate-1985, Marty confronts Biff about the Gray's Sports Almanac while he's bathing in a hot tub with two bimbos, and he tells them to leave so he can talk to Marty privately about the Time Travel secret behind his wealth.
• Retcon:
  • A slight one with the scene the first movie left off. In the first film, when Marty asked if he and Jennifer become "assholes or something?", Doc immediately and earnestly says no. In this film, when Marty asked that same question, we get a brief glance of Doc hesitating at first before hurriedly saying no, letting the audience know he's lying.
  • 1955 Lorraine telling Marty that she'd, "Let [her] kids do anything they wanted, anything at all" and Marty saying he'd like to have that in writing wasn't there in the final cut of the first film, though it was part of the script originally, and was reincorporated in this one.
  • Although Biff harassed Lorraine in the first movie, there was no implication that he had any long-term interest in her. In Part II, it's made explicit that Biff's feelings for Lorraine constitute a Villainous Crush.
• Retractable Weapon: The expanding baseball bat used by Griff Tannen in 2015, which he uses to attack Marty.
• Revealing Reflection: While trying to get the almanac from Biff's car, Marty begins creeping up along the driver's side on his hoverboard, but Biff sees him in the side mirror and is ready when he gets close enough.
• Revolvers Are Just Better: Biff's snub revolver. Handy for silencing environmental activists, popular sci-fi authors whose wives you covet, and meddling kids who know too much.
• Rewatch Bonus:
  • In the 2015 scene at the Cafe 80s, the noticeable physical differences between Marty and Marty Jr. (eye color, shirt color, their hair, etc) are easy to miss the first time you watch the movie.
  • Rewatching this movie after having watched Part III makes the foreshadowing put into it for the ending and the next film stand out more.
• Riddle for the Ages:
  • What sort of illegal activity was Marty talked into by Needles? Embezzlement? Insider trading?
  • According to the time machine readout, Old Biff returns to 2015 at 6:38 p.m. on November 12, leaving all sorts of questions as to why he took so much time between giving the Almanac to his younger self (he arrives in the morning) and returning to 2015, where it would be imperative to return the time machine as soon as possible. These range from nostalgic sightseeing to waiting until dark to avoid being discovered.
• Ridiculous Future Inflation: A single-serving bottle of Pepsi costs about $50 in 2015.
• Ridiculous Future Sequelisation: A holographic advertisement for Jaws 19, directed by Max Spielberg, with the tagline: "This time it's really, really personal." All Marty has to say is, "The shark still looks fake."
• Ripple-Effect-Proof Memory: Doc and Marty arrive in a Bad Future with their memories intact — but it's implied they need to act quickly to prevent themselves from fading into what their alternate timeline counterparts are doing, which for Marty is at a boarding school in Switzerland and for Doc is in a mental institution. It's not clear whether they've replaced these counterparts, but it conveniently prevents them from running into themselves.
• Road Apples: has just Biff who crashes into the same manure truck after Marty evades him again with assistance from Doc Brown in his flying DeLorean time machine.
  Biff: Manure! I HATE MANURE!!!
• Rooftop Confrontation: Biff vs. Marty on the top of the casino.
• Rule of Three: Strickland-A gives Marty three seconds to leave the former's porch with his nuts intact.
• Running Gag: Biff has seen the time machine in every single time period they go to:
  • 1985 Biff sees a "flying DeLorean" leave the McFly home and disappear.
  • 2015 Biff sees the DeLorean again and chuckles that he hasn't seen one in 30 years, but is distracted by seeing two "Marty"s.
  • 1985-A Biff doesn't have time to register fully either as he's knocked cold by the gull-wing door.
  • 1955 Biff sees it in flight, but smashes into a manure truck right after.
• San Dimas Time:
  • Doc rushes to get Marty in position to pretend to be his own son in 2015, and his watch is synced up to 2015 time to make sure he's got his timing right. But if he's wrong, he's got a time machine and can start again- except he doesn't seem to realize this as an option.
  • Much of the tension comes from direct causality; in Part II they recognize that the 2015 Biff changed the distant past to create an Alternate Timeline when they returned to 1985. Marty initially suggests going back to 2015 to stop Biff from changing the past, but Doc points out the alternate timeline will have reached 2015, so they need to figure out when in the past Biff changed the timeline. In fact, this leads to another issue: since they learned that Biff won his first millions at the horse race on his 21st birthday in 1958, which was in one of the books that Doc brought from the library, and after Marty learned about the earliest point being 1955, Marty and Doc never seem to think of going between then and 1955 to steal the alamanac back at a better point in that three year span of time so that they wouldn't risk running into Part I Marty and 1955 Doc.
• Say My Name:
  • Marty's future boss yells "McFly!!" right after he does the illegal transaction with Needles.
  • At the end of the film, the Western Union courier yells "Mr. McFly!" to get his attention after Doc disappears.
• Screw Destiny: we learn that Marty wound up in an auto accident because he got called "chicken", leading to him working in a menial job that he gets fired from after being called "chicken" again. After considerable Character Development in Part III, Marty avoids the auto accident, and a message Jennifer took from the future, telling his future self "You're fired" gets erased.
  Jennifer: Dr. Brown, I brought this note back from the future and now it's erased.
  Doc: Of course it's erased!
  Jennifer: But what does that mean?
  Doc: It means your future hasn't been written yet! No one's has! Your future is whatever you make it, so make it a good one, both of you.
• Screw the Rules, I Have Money!: Biff-A, not surprisingly.
  Biff-A: Kid, I own the police!
• Sean Connery Is About to Shoot You: Taken to a whole new level by the animated holographic advertisement for Jaws 19 ("This time, it's really really personal!") that Marty encounters, in which a shark eats you.
  Marty: Shark still looks fake.
• Second Chapter Cliffhanger: It resolves the alternate timeline story but Marty winds up trapped in the past and everything else is saved for a big fat "To Be Concluded".
• Second Episode Morning: The movie ends on a cliffhanger, with Marty announcing to Doc that he came back from the future, just after Doc sends him back to the future in a sequence first shown in the first movie. This causes Doc to faint, and after waking up at home in the beginning of Part III, he dismisses the encounter as a hallucination... until he bumps into Marty, who's right there with him in the room and who continues to claim that he came back from the future.
• Self-Deprecation: Marty mocks the holo-shark from Jaws 19 (This time it's really, really personal), saying it still looks fake. Spielberg directed Jaws and produced the Back to the Future trilogy.
• Sentenced Without Trial: In 2015, Marty learns his future son Marty Jr. gets sentenced to 15 years in the state penitentiary for his involvement in a robbery within two hours of his arrest, with Doc saying "The justice system works swiftly now that they've abolished all the lawyers."
• Serial Escalation: The first film was ultimately a Fish out of Temporal Water comedy with low, but still personal stakes (Marty returning to his time period and preventing the erasure of his and family's existence). This time, it's not just Marty's family at stake; it's also Doc's life, Hill Valley, the entire United States (not to mention the entire world), and the future itself if they can't undo 2015 Biff's actions.
• Set Right What Once Went Wrong: Marty suggests going back to 2015 to stop Old Biff from taking the Almanac to the past. Naturally, Doc tells him it doesn't work that way; since they are stuck in 1985-A they'll only be going further into a Bad Future. Instead, they have to intercept Old Biff in the past and prevent Young Biff from getting the book.
• Shout-Out:
  • The nostalgia curio shop window has a plush Roger Rabbit doll (another Amblin movie directed by Zemeckis and featuring Lloyd).
  • It also features the Jaws NES game and a VHS copy of Jaws 2. (Not to mention the Jaws 19 hologram.)
  • The virtual Michael Jackson, Ronald Reagan and Ayatollah Khomeini are modeled after Max Headroom.
  • The tv screens in the Cafe 80s all display tv shows owned or produced by Universal Television (Miami Vice, Knight Rider, etc. can be seen).
  • Marty Jr. shouts "Hey, I'm walkin' here!" at a taxi.
  • It's a Wonderful Plot: Many references to It's a Wonderful Life during the 1985-A sequence. 1985-A Hill Valley is a not-so-subtle reference to Pottersville, and you just substitute Biff in Potter's place.
  • One of the articles in the paper in 1985-A about Doc Brown being committed reads "Nixon to seek fifth term", a possible shout-out to Watchmen.
  • In 2015, there's a poster which says "Surf Vietnam". This doubles as foreshadowing, as the Vietnam War is still grinding on in a dystopian Biffverse.
  • Biff's line "I own the police" is a reference to a similar line in Chinatown concerning Noah Cross, another morally bankrupt magnate whose power leads to a dystopian reality.
  • Blink and you'll miss it, but the StarCar from The Last Starfighter can be seen in 2015. You can catch it just as the Jeep rockets down from the sky in the chase sequence.
• Shown Their Work:
  • The college football scores Biff hears on his car radio are the actual scores of actual college football games played on Saturday, November 12, 1955 — except, oddly, the Texas A&M-Rice matchup, which the radio announcer says A&M won 20-10 when the actual score was 20-12. Bob Gale said he personally researched the scores of that day to avoid the wrath of sports fans who would call him out if they weren't accurate. The UCLA game the Biffs listen to also correctly notes the Bruins played at the L.A. Memorial Coliseum; although it opened in 1922, the Rose Bowl wouldn't be the home of UCLA football until 1981.
  • It's true that nobody really knew what CPR was until roughly two years later.
  • October 21, 2015 did fall on a Wednesday.
• Shrine to Self: The Biff Tannen Museum!
  Museum Narrator: Ladies and gentlemen, welcome to the Biff Tannen Museum! Dedicated to Hill Valley's #1 citizen, and America's greatest living folk hero, the one and only Biff Tannen!

  Biff: Third time's a charm. [lecherously kisses Lorraine]
• Significant Reference Date: In the 1985-A timeline, George McFly was killed on March 15, 1973. Julius Caesar was killed on March 15 aka the "Ides of March".
• Signs of Disrepair:
  • In 2015, Hilldale's sign has been vandalized from "The Address of Success" to "The Address of Suckers".
  • In 1985-A, the "Welcome to Hill Valley" sign has an E spray painted over the I, spelling "Hell Valley".
• Slasher Smile: Griff gets off a good one on Marty's failed Look Behind You.
• Slipping into Stink: Marty manages it again, this time distracting Biff long enough to get the Almanac back that he once more crashes into a manure truck. The same one from the first movie to boot. Meaning in the context of the '50s timeline, it happened twice in one week.
• Small Role, Big Impact: Terry, the guy in 2015 trying to collect a donation from Marty before commenting on his desire to go back in time to bet the Cubs will win that year's World Series. That comment starts the Almanac plot and is the reason Doc and later Marty go to 1885, resulting in Clara Clayton being saved from falling into a ravine and Jules and Verne Brown existing. If not for this, Doc would have disassembled the Time Machine after he and Marty returned from 2015. We do later see a younger version of Terry in 1955.
• The Smurfette Principle:
  • Jennifer Parker. Robert Zemeckis and Bob Gale say that if they had intended to do a sequel at the time they made the original film, they would not have put "the girl" in the car at the end. Sure enough, she's sedated less than five minutes into the movie, and while she does get a bit of screentime in the first act (since the audience sees Marty's and Jennifer's 2015 household through 1985 Jennifer's perspective), she faints once she sees her older self and is out of action for the rest of the trilogy, only waking up again in the denouement of Part III. It's especially telling that when Doc explains to Marty the alternate 1985 that they're in, he claims that this alternate timeline is "alternate to you, me, and Einstein, but reality to everyone else", completely neglecting to mention Jennifer who came from the same original 1985 as they did. (Strictly speaking, Jennifer fits neither category, as she spends her entire time while physically in the alternate 1985 in a profound unwoken faint, so her consciousness never really existed in this timeline to even be able to perceive it and to compare it against her original reality.)
  • Griff's gang of four (himself included) in 2015 has one girl, Spike, which is still more women than Biff's or Buford's gangs had.
• Spear Carrier: The kids unimpressed by Marty's gun skills.
• Special Effect Failure: An in-universe example; Marty remarks that the holographic shark used to promote the fictitious Jaws 19 still looks as fake as the original Jaws sharks.
• Spinning Paper: The video at the Biff Tannen Museum uses this editing trick while showing newspaper headlines documenting the Biff-A's life story, including his winning streak.
• Spooky Silent Library: The library in the Biff Tannen-altered Hill Valley 1985.
• Spotting the Thread: Downplayed when Doc and Marty are trying to figure out when Old Biff gave the Almanac to his younger self. While it's not explictly pointed out, it's still evident to them and the audience that the handover had to have happened prior to March 28, 1958 (when Biff made his first million betting on a horse race). While that does narrow down their target window, it's still ultimately a temporal needle in a haystack. As Marty grimly realizes, only Biff himself can fill in the gap.
• Stating the Simple Solution: Suggested by Marty when he and Doc attmept to figure out how to erase 1985-A and restore the normal timeline. Marty's pitch is actually not a bad idea: Just go back to 2015, stop Old Biff from stealing the Time Machine in the first place, and thus prevent this entire chain of events from ever happening. However, as Doc reveals, that option's a no-go because they're already past the point where 2015 Biff changed history. Traveling to 2015 from here will only take them to the 2015 of this hellish reality.
• Starter Villain: Griff Tannen, Biff's grandson in 2015. Marty's task in the first part of the film is to stop Griff from ruining Marty Junior's life. After Griff is jailed for damaging the courthouse in a chase, at least three versions of Biff take over as Big Bad; the elderly Biff from 2015 sets the alternate reality in motion, the 1985 Biff shows the horrible effects of the alterations to the timeline, and the 1955 Biff is the Climax Boss that has to be defeated so Marty can recover the almanac and undo the damage.
• Stealth Pun: The scene where 1985 Doc meets 1955 Doc is one. At that moment, they are a pair of Docs — a paradox. Fittingly, the soundtrack that plays during the scene is named exactly that: "Pair O'Docs"
• Stock Footage: The opening "flying through the clouds" shots that play during the opening credits were originally filmed for the movie Firefox.
• Stolen Good, Returned Better: In 2015, Marty ganks a Mattel-branded hoverboard from a little girl. When he goes to return it, she lets him keep it because she found Griff's high-end, rocket-propelled "Pit Bull" instead.
• Suicidal "Gotcha!": Marty, on the roof of Biff's Pleasure Paradise. Biff-A gets knocked out by the DeLorean doors as well.
• Surveillance Drone: After a ruckus outdoors, hovering robots owned by USA Today swoop down and begin taking pictures for tomorrow's paper.
• Synchronous Episodes: The latter half of the movie overlaps the events of Part I that were set in 1955.
• Tae Kwon Door: After rescuing Marty with the DeLorean in 1985-A, Doc knocks out Biff with one of its wing doors.
  Marty: Nice shot, Doc!
• Take That!: The fake shark from Jaws 19, alluding to the Jaws franchise and its not-so-well-received sequels, especially Jaws: The Revenge, which came out between Part I and Part II and was ripped apart by critics.
• Taken During the Ending: Doc Brown gets struck by lighting while in the Delorean in 1955, making Marty fear he's dead. A letter reveals that Doc was actually taken back to 1885 due to a fluke with the Delorean, leaving Marty to contact 1955 Doc.
• Tap on the Head: Marty gets knocked out by 3-D outside the Pleasure Palace and wakes up with no injuries. This is a part of a running gag, as Marty gets knocked out and wakes up perfectly fine in all three movies. Then there are Biff's flunkies in 1955, who get sandbagged (literally) by Marty at the school dance.
• Tell Me About My Father: Marty, asking Lorraine-A about the alternate version of his father.
• Temporal Duplication: When going back to stop 2015 Biff from giving 1955 Biff the Almanac, Doc and Marty have to work around the fact there's another version of them from the first movie.
• Tempting Fate:
  • In 2015, Needles assures Marty that Fujitsu will not be monitoring their illegal transaction. Naturally, Fujitsu is doing just that and fires Marty.
  • In 1955, the very instant Marty tells Doc to be careful not to get struck by lightning, the DeLorean gets fried by a bolt of it.
• Terminator Twosome: A Terminator Threesome happens Marty and Doc travel back to 1955 to undo Old Biff's tampering with the timeline. To make this more confusing, it's set at the same time as the first movie. So Marty and Doc have to avoid that film's younger Marty who's unaware of other time travellers in order not to mess the timeline up further.
• They Don't Make Them Like They Used To: This is absolutely Truth in Television: DeLoreans feature a fiberglass body overlaid with relatively thin sheet metal (which would sometimes crack during manufacturing). Some of the crash tests show an unbelievable amount of crumpling when hitting a solid wall (though of course, this is designed for the passengers' safety, which an old, solid — too solid, very rigid — car like Biff's would score badly on), so Doc is quite accurate with his observation.
  Marty: Let's land on him, we'll cripple his car.
  Doc: Marty, he's in a '46 Ford; we're in a DeLorean. He'd rip through us like we were tinfoil.
• This Cannot Be!:
  • Heroic version. After being told that his father is in "Oak Park Cemetery" in 1985-A, Marty finds George's grave, and reacts with incredulity.
    Marty: ... No. No! This can't be happening! March 15, 1973?! No! Oh please God, no! No, please God! Please, God, no! This can't be happening! This can't be happening! This can't be...
    Doc: I'm afraid it is happening, Marty! All of it!
  • He does another one earlier when he reads a newspaper; he's in 1985 all right, but some things are drastically different.
  • 1955 Doc has this reaction when, right after sending Marty back to the future, he learns Marty returned to 1955.
• Threw My Bike on the Roof: There's a scene in 1955 where Biff gets a hold of a ball belonging to a bunch of kids, and while listening to them plead to have it back, he mocks them and then throws it onto a second story balcony. The kids stand there, crestfallen, as Biff walks away while cackling to himself(!).
• Thunder Equals Downpour: Played with, The lightning and wind is going nuts, but once the DeLorean is struck and disappears, the lightning and wind stops, and then it starts to pour. That's one crazy storm.
• Til Murder Do Us Part: After giving his younger self the Sports Almanac, Old Biff was erased from existence because Lorraine-A shot Biff-A at some point in the mid-1990s because he was such an awful husband.
• Timeline-Altering MacGuffin: Gray's Sports Almanac, the former Trope Namer, allows Biff Tannen to become wealthy by placing bets on the outcomes of sporting events when his future self gave it to him in 1955. What makes it work is that the Ripple Effect ensures that the Almanac will recursively update to reflect the changes in outcomes as a result of his prior betting, meaning it'll always be accurate. He then uses the money to become a Corrupt Corporate Executive and ruin the lives of Marty (and everyone else in Hill Valley), forcing Marty and Doc to go back in time and stop it.
• Time Travel for Fun and Profit: The old 2015 Biff borrows the time machine for this, giving his 1955 self an almanac with sports scores in the past (although Marty had actually bought the almanac for himself). The funny thing about the almanac is that in Part I, Doc Brown told Marty he was going to learn the winners of the next 25 World Series, then objected strongly to Marty buying the sports almanac in Part II. However, it's implied that he had no intention of profit for the former and just wanted the Fun part.
• Time-Traveling Jerkass: 2015 Biff to a T. He takes Grey's Sports Almanac back to the 1950s and gives it to his past self along with the idea to get rich, which results in 1985-A, a dystopia where Biff murdered George and married Lorraine, who can't get away from him thanks to the power he has. When Marty tries to nab the almanac, he discovers that 2015 Biff also warned his past self about that possibility and he barely escapes with his life.
• Time-Travel Tense Trouble:
  • After Marty realizes that he's responsible for Biff's actions:
    Doc: Well, it's all in the past.
    Marty: You mean the future.
    Doc: Whatever!
  • There's another one, in the middle of the movie:
    Doc: While we were in the future, Biff got the sports book, stole the time machine, went back in time and gave the book to himself at some point in the past.
• Title Drop: The ending.
  1955 Doc: No! It can't be! I just sent you back to the future!
  Marty: No, I know. You did send me back to the future, but I'm back — I'm back from the future.
  [Beat]
  1955 Doc: Great... Scott! [he faints]
• To Be Continued: Audiences were upset they actually showed scenes from Part III. It was deliberately Invoked by Zemeckis and Universal to assure audiences that the last chapter would be finished in a matter of months, not years.
• Took a Level in Badass:
  • 1985-A Strickland. Living in a crapsack world infested with trigger-happy gangs doesn't help.
  • From Griff's perspective, Marty Jr, even though it's actually Marty pretending to be him. He even lampshades that suddenly Marty Jr Grew a Spine (not that it helps Marty).
• Too Many Halves: The 2015 newspaper has a story about a newspaper with fictional news based on the movie that was shown to 5200 people of all ages. 63% thought some of the information was accurate; 18% believed that everything was accurate; and the remaining 29% got the joke immediately. It was also said that 87% didn't realize the percentages added up to more than 100% and the remaining 22% didn't care.
• Trailers Always Spoil: The preview for Part III includes a shot showing Marty, in cowboy gear, making out with Jennifer on her porch, spoiling Marty's successful return to 1985 at the end of the film.
• Tricked Out Time: When Doc and Marty go back in time to stop "young" Biff from getting the Gray's Sports Almanac. Doc warns Marty not to interfere with Biff receiving the almanac from his older self, because they had to make "old" Biff believe that his plan worked so he'll return the time machine (which he stole from Doc and Marty earlier) back to the future where they left it.
• Trophy Wife: 1985-A Lorraine has been coerced into becoming Biff Tannen's trophy wife, complete with unwanted breast augmentation.
• Trumplica: Word of God says the 1985-A Biff was inspired by Donald Trump. The portrait from Biff's office is even based on an actual Trump portrait.invoked
• Trust Password: 2015 Biff gets 1955 Biff to trust him and take the Sports Almanac by demonstrating knowledge only Biff would have, such as how to start his car.
• Two Decades Behind: Invoked and parodied with Gale/Zemeckis' "user-friendly" 2015 A.D. The fashions of the era reflect the '80s at their pastel, animal print and peroxide worst. Kids still wear acid-washed jeans (albeit with the pockets inside-out) and souped-up versions of Marty's vest and Nikes. The biggest offender might have to be Marlene Mcfly, who would fit right in with Saved by the Bell with no alterations whatsoever.
• Two Lines, No Waiting:
  • Invoked: a major hurdle in Doc and Marty's plan to steal the Almanac from Biff in 1955 is that these events take place at the same time as Marty's first trip to 1955. As such, not only do Doc and Marty have to make sure that they don't cross paths with themselves, but also make sure that Part 1!Marty makes it out of the dance in time to get to the Clocktower.
  • This gets exploited at one point: after realizing that Biff still has the Almanac, Marty takes advantage of a brief window of opportunity to nab it from him after George laid him out.
  • It occurs in reverse as well: after Biff provokes Marty after triggering his Berserk Button, Marty proceeds to approach him... only for Part 1-Marty to come barreling out of some doors, knocking him to the ground in the process and causing Biff to steal the Almanac back.
  • And, of course, the most pertinent one: right as Marty and Doc succeed in destroying the Almanac, the lightning storm starts to pick up, and the DeLorean gets struck.
• Tyrannical Town Tycoon: Biff becomes this in 1985-A thanks to the Gray's Sports Almanac, using his business to rule Hill Valley and shape it into a Vice City.
• Tyrant Takes the Helm: After securing his fortune with the almanac, Biff wasted no time in turning Hill Valley into his own personal fiefdom, running the town as a Donald Trump-like dictator.
• Uncanny Family Resemblance: Michael J. Fox plays all of Marty's future family, including his daughter. Although Marty Jr's resemblance to his father is a plot point.
• Unconventional Vehicle Chase: A suspiciously similar scene to that in the first movie happens where Young Biff and his friends chase Marty across the town square on their hover boards.
• Unexpected Kindness: Reeling from Doc's sudden disappearance in a thunderstorm, Marty is suddenly approached by a large, intimidating man in a black coat who menacingly says he has something for him... a letter. Turns out the man is a courier from Western Union and quite friendly, explaining to Marty that they've been waiting to deliver the letter to him since 1885 (it was written by Doc, now trapped in the past).
• Unfazed Everyman:
  • Red the bum. 1985-A hasn't changed him, or his lot in life, one bit.
  • Strickland may count (more like Unfazed Nutball), as he is the same hard-ass disciplinarian he ever was.
• Unintentional Backup Plan: Doc did not intend for Marty to cause Griff and his gang to destroy the entrance to the Courthouse Mall in 2015, but they get arrested for it before they can cause Marty Jr to get in trouble. So, mission accomplished, but not in the way Doc had in mind.
• Unintentional Period Piece: A weird case; the Cafe 80's scene (remember that this movie was made in 1989), invokes this trope directly. The result was rather bizarre at the time, and still is. This is probably intentional, as Doc referred to it as "one of those nostalgia places that's not done very well."
• Unreliable Expositor: When 1985-A Biff recounts receiving the Almanac, he describes himself as being cooperative and interested throughout. When the encounter is later shown, 1955 Biff is actually complaining and dismissive of the book until Old Biff demonstrates its worth.
• Unusually Uninteresting Sight: 1955 Biff does not seem surprised (angry, yes, but not surprised) when "Calvin Klein" tries to steal his sports almanac on a freakin' flying hoverboard!
• The Un-Reveal: Did Needles set Marty up in 2015? We'll never know. His mischievous smirk before he hangs up implies it, though, as if he's telling the Jits, "You're on."
• Unstoppable Mailman: The Western Union man at the end manages to arrive at exactly the time he was told to. Justified in that he and other mail carriers were holding bets on whether or not Marty would be there.
• Unusual User Interface: Implied for circa 2015 video games when two boys in the Cafe 80s watch Marty pull off a Crack Shot in the vintage arcade game Wild Gunman.
  Kid #1: You mean you have to use your hands?
  Kid #2: That's like a baby's toy!
• Unwitting Instigator of Doom: In 2015, Terry (the old man collecting money to save the clocktower) makes an offhand comment to Marty about using knowledge from the future to bet on sports games. This gives Marty the idea to buy the Almanac, with Biff later stealing this idea. The end result is the Biff-horrific 1985 that Marty and Doc go to. When Doc and Marty travel to 1955, we see that Terry was actually the mechanic who fixed Biff's car after it got wrecked in the first film and charged him $300 for, which retroactively make him this trope for that film, too, as Biff's anger about how expensive the repairs were drives him to hunt down Marty and then trying to assault Lorraine.
• Vertigo Effect: Occurs when Marty watches footage of his mother marrying Biff in 1985-A.
• Vice City: 1985-A. Marty's old neighborhood is now a ghetto overrun by wild dog packs(!). Courthouse Square has been replaced with a cluster of strip clubs, casinos, bikers, and roving six-wheeled army vehicles (suggesting a police state which is answerable only to Biffco). These scenes were reportedly the hardest to shoot due to filming near factories (which stank) and motorcycles (which also stank); the whole sequence reminded the filmmakers of Hell.
• Video Phone: The Future McFly household's video phone is connected to the television set. Personal information about the individual on the other end of the line is scrolled through on screen, including name, age, occupation, home address, spouse, children, and assorted hobbies and preferences. Video calling is also sponsored by AT&T. While such tech does exist today, it's provided courtesy of apps such as Discord.
• Villain with Good Publicity: Biff Tannen in 1985-A, if his museum video is to be believed.
• Visual Pun: Look at Biff's hand in the Biff Tannen Pleasure Paradise logo. He's got money to burn.
• Waking Up Elsewhere: Marty wakes up after being knocked out by 3-D. He drowsily assumes that the past several hours have been a bad dream when he finds himself comforted by his mother, reassuring him he's safely home with Biff. The news shocks him awake and leads to a brief freakout.
• Was It Really Worth It?: The 2015 timeline showed that Marty had been provoked into doing incredibly stupid things whenever someone calls him chicken, adamant to prove he's not a coward. This always cost him dearly which, according to 2015 Lorraine, cause Marty to give up his music due to suffering a crippling hand injury as a result of a car accident after getting goaded into a street race years prior. 2015 Marty still doesn't learn his lesson when 2015 Needles goads him into committing what he knows is an illegal business practice just to prove he's not a chicken. This prompts his employer Fujitsu to terminate him for the illegal transaction over the phone. 2015 Marty loses his job over his pride, which he's clearly not happy about. But hey, at least he's not a chicken, he's just an idiot.
• Weather-Control Machine: Doc mentions a U.S. weather service in 2015, after predicting the exact time rain would stop. It's somewhat unclear whether they actually have the ability to control the weather, predict it with extreme accuracy, or if Doc actually only knew through time travel.
• We Will All Fly in the Future: The then-futuristic year 2015 is portrayed as featuring streams of flying cars and "road" signs that somehow hover in mid-air.
• Wham Line:
  • Marty, after seeing how Biff-A treats Lorraine-A in 1985-A, asks what happened to George. And, in retrospect, he probably shouldn't have:
    Lorraine-A: Marty! George— your father is in the same place he's been for the past 12 years... Oak Park Cemetery...
  • Gets even worse when Biff-A, while threatening Marty with a gun, has this exchange on the roof:
    Marty: What about the police, Biff? They're going to match up the bullet with that gun.
    Biff-A: Kid, I own the police! Besides, they couldn't match up the bullet that killed your old man.
    Marty: You son of a...
    Biff-A: I suppose it's poetic justice: two McFlys with the same gun.
• Wham Shot: The scene when Marty realizes that the "almanac" he retrieves after many struggles is a decoy (an issue of the Oh La La magazine with the almanac's removable dust jacket placed on it by Biff). Especially because, at that point, Marty doesn't have any clues on where Biff (who still has the real almanac) might be and the clock is ticking. It gets better when Marty sees Biff bullying George and hope is reignited.
  Marty: YES!... [looks at the pages] No! "Oh La La"? "Oh La La"?!
• Which Me?: A few times, given that Michael J. Fox is playing our Marty, 2015 Marty, Marty Jr., Marlene, and his past 1955 self. Meanwhile, Thomas F. Wilson is playing 2015 Biff, Griff Tannen, 1985 Biff, 1985-A Biff and 1955 Biff.
• Wicked Stepmother: Biff-A is really abusive, not just to Lorraine, but also to his own stepchildren, Marty among them. Lorraine's line "They must have hit you over the head hard this time..." after Biff's tirade implies that Marty-A gets physically abused often; Biff loves to give Dope Slaps, so it's not out of character for Biff. What's more, he makes it a point to coerce Lorraine to get with the program by threatning to send her children to jail for debt. Not to mention that Biff-A has no qualms about shooting Marty once he reveals he knows about the sports almanac.
• With Friends Like These...: Needles isn't a bully in the sense that the other McFlys faced, but he does antagonize Marty in his own (ahem) needling way.
• With Great Power Comes Great Responsibility: As stated by Brown in this movie, not using Time Travel for personal gain was one of his self-imposed policies on his and Marty's trips in the trilogy. In this movie, Marty considered making easy money with a time machine, but Biff Tannen beat him to using a future sports almanac to gamble on past events, which resulted in drastic changes in the timeline. However, like other rules — not using information from the future and avoiding one's other selves — Doc eventually disregarded this rule anyway after finding his love in 1885.
• Women's Mysteries: Doc mentions this while musing that he won't get to visit The Wild West.
  Doc: Better that I devote myself to study the other great mystery of the universe — women...
• Worst News Judgment Ever:
  • The front page of the USA Today on October 22, 2015 is the news of Marty Jr being arrested for robbing a payroll station.
  • In 1985-A, Doc holds up a newspaper where the front page story is about how he was proclaimed insane and committed in 1983-A. While he is a strange, prominent figure in the town, it doesn't really merit the front page.
• Would You Like to Hear How They Died?: Biff-A crows to Marty about murdering his father (with the same gun he currently has trained on Marty, no less) and getting away with it.
• Write Back to the Future: Doc's letter from 1885 to 1955, informing Marty of his current situation, and the location of the DeLorean.
• Written-In Absence: The movie had its entire plot reworked when Crispin Glover wanted too much money to reprise his role as Marty's father. Instead of a trip to the 60s (where George was a flower child), we go to an alternate 80s where Biff had become extremely wealthy thanks to a certain book, and George was dead.
• You Already Changed the Past: Doc's letter at the end sort of plays this trope straight (the only part of the trilogy to do so), though Rule of Cool applies for obvious reasons. This is debatable however, as since the letter arrives after the DeLorean gets struck by lightning, it could be argued that the Western Union guy wasn't there at all until the ripple effect kicked in. Alternatively, since Doc took The Slow Path to send that letter, the ripple effect kicked in a long time ago, the viewer just doesn't get to see it. The Western Union guy is the only instance of a character being present (and on-screen) for an altered event rather than simply having or, in Marty's case, being a ripple-affected artifact that's been temporally displaced.
• "You!" Exclamation: Biff to Marty, after awakening from being knocked out by George.
  Biff: You!
  [Marty punches Biff again, and takes the Almanac]
  Marty: He's fine!
• You Just Had to Say It: Just after Marty warns Doc not to get struck by lightning at the end of the movie, he does.
• You Killed My Father: Biff-A murdered George-A.
• Your Princess Is in Another Castle!: Marty finally gets the Gray's Sports Almanac from Strickland which got confiscated from Biff... only to find out that he only has the dust jacket and it contains Biff's sexual magazine Oh Là Là! The actual almanac is still in Biff's grasp.
• Zeerust: Done on purpose; the filmmakers didn't want to try to accurately predict the future, so they just combined Jetsons-esque devices with some obvious jokes. (The McFlys have a fax machine in every room of their house, which apparently all print the same message at once. ^note A thermal paper fax machine, at that. Some of the printouts have been seen at conventions years later, already decaying due to temperature exposure.) It's more notable to list their predictions that actually came pretty close.
  • Things like 16:9 flat-screen TVs with the ability to watch multiple shows at once don't sound too crazy in a world with Google TV. Hell, think about Marty Jr. watching about eight shows at once, then ask yourself: how many tabs do you have open in your browser right now? (Of course, they completely missed the internet, but so did nearly everyone.)
  • The film shows machines that respond to voice commands, not at all implausible now that we have Siri, Alexa, the Google Assistant, and others.
  • And the thing of a video-phone being integrated into those 16:9 flat-panel TVs? Smart TVs as early as 2012 were being touted as supporting Skype video-calls when equipped with an attachable USB camera/mic combo (sold separately, of course)
  • The Chicago Cubs won the World Series in 2016. The movie was off by a year.
  • The idea of a robot dog-walker (like Marty sees in Hilldale) doesn't seem so farfetched, given the growth of the personal robot market in recent years. The flying thing's unlikely, though.
  • Jennifer enters her future self's home by placing her finger on the fingerprint lock of the entrance door. While this kind of technology is still not usual domestically (due to being expansive, at least compared to traditional locks), fingerprint locks are a reality even before 2015. Many smartphones now have NFC technology that allows one to make credit card payments without a physical card. Fortunately, the MO of the "Thumb Bandits" is impossible; in reality, the thumbs (and other fingers) used must still be attached to living bodies.
  • College Humor did a parody of what Part II's 2015 sequence would be like if 2015 as it's turned out for real was used.
  • The October 21, 2015 episode of Jimmy Kimmel Live! had Christopher Lloyd and Michael J. Fox playing Doc and Marty arriving in the actual 2015 and being disappointed with it.
  • USA Today published a "Hill Valley Edition" on October 22, 2015, reporting on the arrest of Marty McFly Jr. The last story on the front page bears the headline, "Public More Gullible Than Ever", and uses Lies, Damned Lies, and Statistics to detail an experiment from the Sam Houston Institute of Technology apparently revealing how easily readers might mistake the paper's stories for actual events.

Marty: Okay, relax, Doc, it's me! It's me, it's Marty!
1955 Doc Brown: No, it can't be! I just sent you back to the future!
Marty: Oh, I know you did send me back to the future. But I'm back, I'm back from the future!
Doc: Great... Scott! (faints)
Marty: Doc! Doc. Doc. Oh, fantastic...
