Marty McFly: Wait a minute, wait a minute, Doc...are you telling me you built a time machine... out of a DeLorean?! Doc Brown: The way I see it, if you're gonna build a time machine into a car, why not do it with some style?
Adorkable: George McFly. Especially as a teenager, an Extreme Doormat as an adult, walked over by everyone. A bit more of a smooth operator as an adult after Marty slightly alters the future, but as a senior in one possible timeline, prone to a brittle back.
The Alleged Car: The films don't hide the fact that despite the cool looks the Delorean DMC-12 was a troublesome car which broke frequently. It's particularly bad in the first movie, so maybe Doc worked some of the kinks out with the hover conversion?
Alliterative Name: Marty McFly; Clara Clayton; Marty McFly Jr.; Marlene McFly; Maggie McFly; S. S. Strickland
The names of the goons from Biff and Griff's gangs, as well as Lorraine's friends. The most easily recgonizable is 3-D, wearing cardboard 3-D glasses in his youth, and aviators with red and blue lenses as a vice thug in the Bad Future.
As well as other info of the characters' backgrounds. Including Doc's mother's side of the family growing up in Hill Valley.
Almost Kiss: This happens three times in Part I, between Marty and Jennifer (though they did share a brief kiss before she went home with her dad). Towards the end of Part III, the two are finally able to kiss more definitively.
Aluminum Christmas Trees: The DeLorean. The DeLorean Motor Company went bankrupt in 1982, well before the film was made, and Robert Zemeckis had to argue with Universal to use the car since DMC wouldn't be able to give them any commercial endorsements. At the time the car was considered a failure; it's now entirely thanks to this series that anyone remembers it.
The use of the word "Dude" as an insult in the 1885 segments. Back then it was pretty much equivalent to "City slicker" or "Dandy", and meant someone from an urban environment trying to play cowboy. (It is still used this way when referring to a "dude ranch".) Its use as a term of affection only goes back as far as The Sixties.
Applied Phlebotinum: The flux capacitor makes time travel possible. Never mind figuring out how, it just does. Lampshaded by Marty.
"Nobody... calls me chicken." (With a variation in Part III, where the equivalent word is "yellow") This particular berserk button appears to be subject to sequel retconning, as it is nowhere in evidence in Part I.
The first time the DeLorean travels through time, it leaves its registration plate spinning on the spot behind it. After the DeLorean makes its final journey and gets destroyed by an oncoming train, the car's registration plate from 2015 is left doing the same thing.
In the original film's climax, Marty returns to the shopping mall just moments before his past self warps to 1955. The only difference is he's returning to Lone Pine Mall, not Twin Pines Mall.
"The Power of Love" by Huey Lewis & The News is played in both the second scene of the first film, and the second-to-last scene in the final film.
Marty's first and last lines in the trilogy are "Hey, Doc?", though in Part III, Marty adds "Where are you going now, back to the future?"
In 2015, we find that Marty's future life is not going too well, the result of his life going down the toilet after a car accident when he got challenged by Needles, who called him "chicken" to a street race, in which Marty collided with a Rolls Royce and broke his hand, and the driver of that car pressed charges. Marty gave up on his music career and has been resorting to rather desperate means to stay afloat, to such that he agrees to participate in an illegal business deal with Needles after Needles calls him "chicken", and gets a bunch of YOU'RE FIRED!!! faxes from Fujitsu as a consequence. Then the main plot kicks in, which sends Marty and Doc back to Alternate 1985, then to 1955, and then to 1885 for the remainder of Parts II and III. When Marty returns to the present and picks up Jennifer, they are driving in Marty's new 4x4 pickup past the entrance to Hilldale, the neighborhood where the future Marty will live, and our Marty recognizes the place. Just then, Needles and some of his pals pull up alongside Marty and the "chicken" thing comes up. Marty looks like he's going to give in and race Needles, but Jennifer persuades him not to. So when the light turns green, Marty floors his vehicle in reverse while Needles speeds forward. As Needles barrels down the street, he and his pals narrowly swerve to avoid an oncoming Rolls Royce making a left turn off a side street, and Jennifer realizes it's the car Marty would have hit.
In Part I Doc holds his experiment at the Twin Pines Mall, casually mentioning it used to be farmland, and that the owner tried to breed pine trees. When Marty travels back in time, he ends up on Old Man Peabody's farm, also known as Twin Pines Ranch. When Peabody begins shooting at Marty with his shotgun, Marty is forced to flee towards the road. As he's driving, notice that there are twin baby pine trees next to the dirt path, fenced in to protect them. In fleeing, the car ends up smashing through and destroying one of the two trees. Over an hour later, we find ourselves back at the beginning, only this time we're at Lone Pine Mall, implying that Peabody did not try to replace the pine tree that was destroyed.
The name of Clayton Ravine: Marty says that it's named after Clara Clayton, who fell to her death there — at least, she did until the Doc rescued her. When Marty returns to the future, the ravine is now named Eastwood Ravine, presumably to honor Marty (going by the name of "Clint Eastwood") who had faced down the robber and murderer Buford Tannen before (as far as they knew) dying in the ravine.
Bullet Proof Vest: In all three movies; they seemed to like this trope. In real life, only Marty's improvised "stove-door vest" out of the Dollars trilogy in Part III would have worked; the high-velocity rounds from the Libyan's AKM would have torn through Doc's vest like it wasn't even there.
Burning Rubber: The DeLorean leaves twin trails of fire in the "old" time period after it jumps to the "new" time period.
Butterfly of Doom: Most of the first film, and much of the sequels. Namely, thanks to old Biff handing that almanac to his 1955 self, A-Biff was able to manipulate history enough that in 1985, Nixon was in his fifth term as President, and the Vietnam War was still ongoing.
Several set pieces (such as a Tannen and his gang chasing Marty in front of the Clock Tower) are reused throughout the trilogy, to show that history repeats. Lampshaded by 2015 Biff: "There's something very familiar about all this."
The fundraisers trying to save the clock tower did, indeed, manage to save it.
Doc justifies sending Marty to 1885 in the middle of the desert by saying "You don't wanna crash into a tree that once existed in the past". In the first film, one of the first things Marty did after arriving in 1955 was (accidentally) run down one of Old Man Peabody's twin pines.
When Doc Brown makes a model of Hill Valley in the first movie, he apologizes to Marty that "this is not to scale." Lampshaded in the third movie when Marty interrupts him and says, "Yeah, I know. It's not to scale."
In all three films Marty wakes up in bed, believing his time-traveling escapades have been a nightmare. He is comforted by a character played by Lea Thompson (Marty's mother Lorraine in 1 & 2, his great, great grandmother Maggie in 3) by being told he's safe and sound in some place that jars him and reminds him it's not a nightmare after all.
The Tannen family has every reason to hate manure.
A blink-and-you'll-miss-it example occurs in the second film when Marty (indirectly) causes damage to Griff's car. Marty had previously done so to Biff's car in 1955, though in a different manner.
In the third film, before he gets out of bed at the McFly farm in 1885, Marty stops to make sure his pants are on, after Lorraine removed his pants in 1955.
Car Fu: In Parts I and II, Biff tries to run Marty down with his car. Both times he crashes into a truck carrying large amounts of manure.
Doc's "Great Scott!" and Marty's "This is heavy!" Inverted in Part III, where they once exchange lines.
In the second and third films, Marty also developed the Catch Phrase "Nobody calls me chicken!" (or "yellow" in the Western setting) in response to his personal Berserk Button.
Also hilariously lampshaded in the first film: "Weight has nothing to do with this!", "There's that word again, 'heavy'. [...] Is there a problem with the Earth's gravitational pull?"
In the second and third films, Biff and Buford have good reasons to say,"I hate manure." His gang also subverts this in the first movie when they collide with the manure truck with a cry of "SHIIIIIIIIIIIT!"
Strickland seems to think that everyone's problem is that they're a slacker. Drive-by shooters peppering his home with bullets? Well, EAT LEAD, SLACKERS!
Marty's variations on "What's that?" followed by a punch.
Various Tannens as well as Vice Principal Strickland tend to refer to Seamus, George, Marty, and Marty Jr. by their last names.
If you see a manure truck anytime during the trilogy, a Tannen is SURE to get covered deep in it before the movie's end.
The hoverboard: used in the second film multiple times (and in different eras), the device is used again (by Marty) to save Doc and Clara during the climactic train sequence in the third film.
The giant speaker seen at the beginning of the first movie is month's later used in the beginning of Episode 1 of Back To The Future: The Game by Marty to get Doc's notebook back from Biff.
Marty's "auto accident": first referred to in Part II (during the 2015 segment), then narrowly averted during the finale of Part III.
In Part II, Marty watches a scene from A Fistful of Dollars during the 1985-A segment (at Biff's Casino). The scene is question is the part where Clint Eastwood uses steel plating under his poncho to protect himself during a gunfight. Marty then uses this trick (with a boiler plate) in Part III to survive his confrontation with Mad Dog Tannen.
Marty holding onto cars while skateboarding (skitching) in Part I, he uses the same trick (on a hoverboard) in Part II to steal the Almanac from Biff, and to Travel along a train in Part III.
In Part II Marty demonstrates his skill with a gun-based arcade game. This becomes important in Part III, giving him a sporting chance in an actual duel. This is subverted when he removes his gunbelt and lets Buford shoot him in the boiler plate he wears under his poncho — then beats the shit out of him. Also deconstructed by the reason he needs to pull this off- the gravestone photograph shows it would not be enough to save him from an experienced killer like Buford Tannen.
Close Enough Timeline: There are not too many changes to 1985 when Marty returns there in Parts I and III.
Colour-Coded for Your Convenience: The DeLorean's LED displays are red for "Destination Time", green for "Present Time", and yellow for "Last Time Departed", in homage to to The Time Machine 1960. In Part III, Doc has made presto logs, color-coded green, yellow and red, in increasing order of the amount of heat each produced to make their train run faster, with a corresponding gauge showing when it would happen.
Comes Great Responsibility: Doc eventually comes to view the DeLorean as a menace. Considering it's a device that if misused has the potential to undo the universe, he's not far off.
Marty's "chicken" problem, a key element of the sequels, is never even referred to in the first film. There is a scene from Part I where Lorraine, in the car with Marty, says "anyone who's anyone drinks." Marty then takes a sip from the bottle. Of course, this is so he can do a Spit Take, but it could also be theorised that Marty is reacting to indirectly being called "chicken". Another theory posits that the "chicken" thing is a side-effect of the altered 1985 (cf. "the ripple effect") from the first movie — Marty's father (and, by extension the whole family) is more confident; for Marty, this caused arrogant insecurity.
Related is that in Part I, Marty is concerned that nobody will like his audition tape. At the start of Part II, Marty simply assumes he'll become a rich rock star.
Though it could be argued that he's taking Doc's advice of 'achieving anything he puts his mind to' after seeing how that advice worked for George.
Contrived Coincidence: Doc Brown had the revelation for the flux capacitor on the exact same day Marty's parents met. Exactly one week later on November 12, there was the school dance where the two kissed for the first time, and lightning stuck the clock tower. It also happens that the day of the school dance was also the day Old Biff traveled back in time to change the past. This is virtually lampshaded in the second film.
Marty: That's right, Doc. November 12, 1955. Doc: Unbelievable that old Biff could have chosen that particular date. It could mean that that point in time inherently contains some sort of cosmic significance. Almost as if it were the temporal junction point for the entire space-time continuum! On the other hand, it could just be an amazing coincidence.
The DeLorean. Anyone who grew up in The Eighties and enjoyed the BTTF movies will invariably hold a sort of unrequited love for them, even though in their unmodified form they're underpowered and don't handle too well. (Arguably, that's part of the joke — getting a real DeLorean up to 88 miles per hour is about as likely as getting it to travel through time.) In fact, the car is so iconic that these days it's practically impossible to look at a DeLorean without thinking of these movies.
Other examples: Biff's '46 Ford Super DeLuxe convertible, Marty's tricked-out 1985 Toyota 4x4, and Doc Brown's 1948 Packard Victoria convertible.
Marty, everywhen but 1985. In a way, he was also one of these in a-1985!
Inverted with Doc, he seemed to fit in better in 1885 and was a respected member of the community (as opposed to the crazed crackpot rep he had in 1985).
Five-Temperament Ensemble: Biff Tannen (choleric), Clara Clayton (melancholic), George Mc Fly and Jennifer Parker (phlegmatic), Lorraine Mc Fly and Doc Brown (sanguine), Mr. Strickland (choleric/melancholic), and Marty Mc Fly (sanguine/choleric).
The McFly Family: Lorraine (sanguine), George (phlegmatic), Dave (choleric), Linda (melancholic), and Marty (sanguine/choleric).
The ending scene of Part I is also the opening scene of Part II. Since Elisabeth Shue had replaced Claudia Wells as Jennifer, the scene was refilmed for the sequel. The re-shot version is nearly identical, with the only difference being that Doc Brown's face is shown this time, he gives a significant look with his eyes, and hesitates slightly before responding to Marty asking whether he and Jennifer end up as "assholes". You'll notice that they didn't even bother to match Shue's hairstyle with Wells'. Sure, most people didn't notice at first because of the four-year lag in Real Life, but if you watch the two films back to back it can be pretty jarring.
Crispin Glover also didn't return, so in all refilmed 1955 scenes in Part II, George is always seen from behind (except one shot of recycled footage viewed through Marty's binoculars).
The Spear Carrier couple ("Who is that guy?" "That's George McFly...") also get replaced in Part II's 1955 scenes, as do most of the other 1955 extras.
Speaking of 1955 extras, the character Lester ("I think he took his wallet") was played by an unnamed extra in Part I, who could be seen crouching over Biff. Obviously, as Lester became a marginally Ascended Extra thanks to Marty's interference in Part II, he was Other Darrin'd for the sequel.
Goldfish Poop Gang: Young Biff's greaser cohorts. They go by the names of "Match" (Billy Zane, playing a goon with an Oral Fixation), "3-D" (wearing 3-D movie glasses), and "Skinhead" (the one with a crew cut). The trio is still in Biff's employ in 1985-A, now working as corrupt security guards at Biff's Pleasure Palace; Match now sports a ten-gallon hat and bolo tie, Skinhead's gone grey, and 3-D has swapped out his eyewear for Tony Clifton sunglasses.
Hair Today Gone Tomorrow: Subverted with Strickland in Part I as he is shown to be bald in 1985, and in the 1955 scenes, it's seen his receding hairline is on its last legs. Double subverted with the marshal in Part III as the marshal is an ancestor of Strickland's.
Homemade Inventions: Doc has a passion for making these. The time machine being the prime example, more minor examples including a robotic dog-feeder, humongous amp, a mind-reading machine which doesn't work, and a steampunk ice-maker.
Honor Before Reason: Marty is guilty of this due to his Berserk Button of being called cowardly in any way. This has done nothing but gain him more trouble than necessary and making things more difficult than they were before.
Future Marty knew that Needles' proposition was illegal and that he could get fired if he went through with it, but does so anyway when called a chicken. Of course, Future Marty is indeed found out, immediately, by his employer (who was monitoring the call!), whose response is to send out a bunch of faxes reading "YOU'RE FIRED!!!"
This almost gets Marty killed in Part III until Seamus and even Dr. Brown called him out on his stubbornness to not accept being called cowardly.
Hover Board: Picked up in 2015, used in both 1955 and 1885.
I Know Mortal Kombat: Marty is a crack shot, thanks to whiling away his youth playing Wild Gunman. Established and mocked in the second, used straight in the third.
Though "used straight" applies only to the fairground shooting gallery- as the changing gravestone picture shows, it would not have been enough to save Marty in a straight-up duel with Buford "Mad Dog" Tannen, a hardened killer.
"Calvin Klein" is actually a subversion, as Lorraine sees it written on Marty's underwear and believes it's his name. Marty does correct her but she still calls him Calvin. Marty bemusedly goes with it to avoid arousing further suspicion.
"Clint Eastwood", on the other hand, is played completely straight. Marty can't even back out of a duel because not only would it tap his personal Berserk Button, but it would also preemptively ruin the actor's career in Westerns by associating his name with cowardice, and keep the Dollars trilogy or Dirty Harry from featuring him.
Immediate Sequel: Part II and III literally begin seconds after the previous ones, II after I, and III after II.
Incorruptible Pure Pureness: George Mc Fly. As nerdy as he is, he is very nice and won't fight the bullies because he feels it is wrong. Also, Jennifer Parker. She is the sweet, supportive, quiet girlfriend and later, wife of Marty Mc Fly.
Intergenerational Friendship: Marty and Doc. Word of God explains that the friendship started when Marty was around 13-14 years old. After being told for years that Doc Brown was a dangerous, crackpot, lunatic, he snuck into Doc's lab to see for himself and instead was fascinated by what he saw in there and thought Doc's inventions were cool. Doc found him and was happy Marty thought he was "cool and accepted him for what he was". Doc then gave Marty a part-time job helping out with experiments, helping in the lab, and feeding Einstein. Read for yourself.
In Part III Marty befriends his Great-Great Grandfather Seamus. Seamus isn't much older than Marty during the time period though.
It Runs on Nonsensoleum: It's never really explained how the Mr. Fusion device Doc adds to the DeLorean from 2015 is able to generate the requisite 1.21 gigawatts of energy — not to mention undergo nuclear fusion — using an aluminum can and some other bits of garbage, though it's possibly supposed to be a comic-book style of fusion that turns matter directly into energy.
Laser-Guided Karma: For all the crap Biff and his family line tries to pull to Doc and Marty throughout the course of the trilogy, there is always a cart of manure placed just at the right moment to deliver Tannen some sweet, sweet justice.
The Load: Jennifer Parker. Bob Zemeckis and Bob Gale never had a character development in mind for her, stating that had they planned to make a sequel to the original film, they would not have put "the girl" in the car at the end. Sure enough, less than five minutes into Part II, she's sedated and pretty much spends the rest of the series that way. Neither Claudia Wells in the first movie nor Elizabeth Shue in the others are even given top billing in the film credits, even though those who play even smaller roles are.
Look Behind You: Works on most Tannens, although Griff's gang in part 2 has some really neat cybernetic implants. He almost seems a bit surprised when he looks back and finds that his hand has caught Marty's fist. Also doubles as Schmuck Bait.
Mad Scientist: Emmett Brown is the poster child for this trope, but only when he's inventing or planning; because of great writing it's just one facet of his character. He can also be quite lucid and/or calm.
Biff Tannen: "Make like a tree and get out of here!" Lampshaded by none other than the Biff Tannen from 2015: "You sound like a damn fool when you say it wrong!"
In the now-closed theme park ride, 1955 Biff uses marbles to trip up the security staff coming after him and gleefully quips "Have a nice trip, see you next winter!" As he runs off, one of the fallen men says "It's 'see you next fall'!"
Biff thinks pointing out his malapropisms is about as funny as a screen door on a battleship!
Buford Tannen in Part III is also prone to this:
Buford: (to Marty) Eight o'clock Monday, runt! If you ain't here, I'll hunt you and shoot you down like a duck! Gang Member: It's dog, Buford. Shoot him down like a dog.
Men Act, Women Are: With the exception of 1955 Lorraine in Part I, female characters are only there to serve as Satellite Love Interests and victims to male characters. In fact, they had to basically write around Jennifer Parker because she was brought to the future in the end of the first film, but when they actually started making the second film they realized they did not know what to do with her. Rather then Retcon her away, they solved this problem by making her stay sedated for much of the 2015 scenes. See Back to the Future's entry under The Load.
"Mister Sandman" Sequence: The Trope Namer, at least once in each movie, after Marty arrives in a new time period. It is to show what Hill Valley looks like in 1885, 1955, or 2015.
Model Planning: A Running Gag. Doc Brown builds elaborate models of city blocks or canyons to demonstrate his plans to Marty, then apologizes for "the crudity of the model". It also catches on fire, repeatedly.
My Car Hates Me: The DeLorean has a tendency to fall into disrepair at the exact moment Marty lands in another time period. Sometimes, however, justified: in the first movie, the plutonium needed to power the flux capacitor isn't available, and in the third movie, the fuel line is damaged during an Indian pursuit and the gasoline leaks out, which the car needs to accelerate. The DeLorean's habit of stalling in the middle of a road has prevented possible time paradoxes: In the original movie, Marty is forced to disguise the car behind a billboard, being unable to drive it openly through 1955 Hill Valley. By stalling right before the final run towards the clock tower it delayed Marty about 30 seconds; if he had started driving when the alarm went off he would have beat the lightning bolt and been stuck in the past for the rest of his life. At the end of the film, the DeLorean stalls again, preventing Marty from interrupting the shootout at Lone Pine Mall (thus avoiding direct contact with his past self).
Nice Job Breaking It, Hero: Oh so very much. It seems like poor Marty can't go long without accidentally making the timeline worse thus requiring the need to undo the damage. "Saving" George from being hit by the car in Part I and buying the Sports Almanac in Part II were probably the worst cases. Not to mention any time Marty loses it whenever he gets called "chicken", which ends up making most situations twenty times worse.
No Communities Were Harmed: Outside of the iconic Universal Studios clocktower square set, "Hill Valley" is a mix of various SoCal communities. The zip code on Marty's fax is the same as Caspar, California.
No Man Should Have This Power: Doc Brown repeatedly promises to himself to destroy his own time-travelling technology, which finally happens at the end of Part III. (And then it almost immediately turns out that he had built a new one.)
No Pronunciation Guide: For "gigawatts". Not so noticeable to the general public at the time, but over 20 years on, the prefix "giga-" (beginning with a hard "g") has become commonplace for computer-related termsnote (Gigabyte and gigahertz likely being the most commonly known among the average computer user), so nowadays it's bound to give even non-engineers pause. (Or, make people think you're referencing Back to the Future...)
The time-traveling steam locomotive at the end of Part III, which also flies!
Percussive Maintenance: Marty bashes his head against the DeLorean's steering wheel when it refuses to start. At this, the ignition miraculously turns on. Doc is also seen giving his timer readout a whack in Part II when it flickers "1885"; he becomes stranded in that time period when lightning strikes the car.
Pick on Someone Your Own Size: Tom Wilson jokingly described the Tannen clan as evil incarnate, though that's not far off. Biff has tried to kill Marty twice, once in the past and again in an alternate reality. Buford spent an entire movie hunting him for no particular reason, really.
Pimped-Out Car: Doc made a time machine out of a car, and later a train, not to mention the flying abilities.
Playing Gertrude: Lea Thompson is just nine days older than her onscreen son Michael J. Fox. Crispin Glover is actually three years younger than Fox, and Thomas F. Wilson is just two years older than Fox. This trope is played straight when it comes to scenes in 1985. But it becomes averted once we go back in time to 1955, where Thompson, Glover, and Wilson are playing their characters at or around Marty's age.
Pretty in Mink: In the first two films, there is a girl wearing a white fur shoulder wrap among the crowd gathering around a knocked-out Biff. This is notable because the actress is noticeably different in the two films, and in the first films she is amazed George finally stood up for himself.
Plenty from Pepsi, to the point it's amazing they didn't try to work it into Part 3. For a really good example, watch the scene between Marty and George just after the "Darth Vader" scene... notice that Michael J. Fox never completely covers the logo of his Pepsi bottle. Also, the writers had to fight to keep the "give me a Tab" gag in the first movie, because Pepsi didn't want Marty mentioning another company's soda. The futuristic Pepsi glass in Part II makes it look awfully good, though
Ditto from JC Penney, which gets shown at least three times of the trilogy.
The local Texaco station catches Marty's attention in 1955 when an army of servicemen come out to take care of one car. In 2015, Marty gawks at a giant robot operating the station.
Also meta-funny, given that full-service stations are nearly extinct in Real Life. apparently 2015 Texaco decided to resurrect the concept, but with ROBOTS!
Forget West Point. To master firearms, visit your local 7-Eleven. Foreign dubs reference Disneyland instead.
The producers also put a Zale's Jewlery ad onto a Courthouse Square bench in Part I, and Zale's neon signs in the 50s scenes of both Part I and Part II. This was done mostly as a play on the names Zemeckis and Gale.
The first piece of audio heard in the first movie is an ad for a Toyota dealer, which plays on Doc's radio. In 1955, this dealer instead sold Studebakers.
During the pre-production of the first movie, someone negotiated an endorsement deal with the state of California's Raisin board that Back to the Future could do for raisins what ET had done for Reese's Pieces. He came back and told the writing staff that they needed Marty to habitually eat raisins throughout the film. The execution kept getting scaled back until the final inclusion of raisins was a single poster on the park bech the drunk is sleeping on when Marty returns to 1985. The California Raisin board was not happy and demanded their money back.
A number of these instances were invoked, specifically the producers choosing brands whose 1955 logos were very different from their 1985 counterparts.
Western Union will deliver a packet precisely when and where you ask. Even if it takes 70 years!
Rule of Cool: Doc made his time machine out of a DeLorean out of style. He does begin to mention that there was a reason based of the car's aluminium structure, but is cut off before he can fully explain it.
The Tannen name will be forever associated with open-top cars rear-ending manure trucks or simply taking a stumble into a manure pile, and yelling "SHIIIIIIIIIIIT!" when the brown disaster is imminent.
Marty's inability to get the fashions of the period right. Taken to the extreme with the cowboy outfit in Part III. To be fair, in Part III the clothes are picked by 1955 Doc, and even Marty questions their authenticity.
Whenever Marty finds himself in a new era or timeline, he can't resist walking aimlessly through the town square gawking, usually wandering right in front of an oncoming car (or carriage).
Marty screaming helplessly as he enters into the a new time period because the DeLorean is often almost always about to crash into something upon arrival.
Recurring family businesses, like the Jones manure truck.
The Hill Valley clock tower is featured in each movie, sometimes pivotal to the story. In chronological order:
Part III shows its construction in progress in 1885, where Marty and Doc Brown appear in an antique photo by the clock face before it gets mounted. Said clock also designates high noon at the climax of the movie.
In Part I, during 1955, a fateful lightning bolt struck it and rendered it inoperable. This bolt was used to return Marty to the future.
Finally, in Part II, the tower has been renovated and restored to functionality as a respected landmark following the success of the petition, with a beautiful glass exterior. Until moronic Griff Tannen smashes through it on his hoverboard like a bull in a china shop and receives the "I was framed!" headline in USA Today paper.
The DeLorean continually breaks down and requires something to get it back to 1985.
Freak lightning strikes causing things to stop working.
The repeated appearances of the prematurely balding and irate Principal Gerald Strickland acting as the rigid authority figure, calling people, "Slackers!" In the third movie, his ancestor takes his place, minus the catchphrase.
Marty sneaking around and then getting hurt in a way that would cause him to audibly scream, and he has to hold his tongue.
Clint Eastwood movies and the usage of a bulletproof vest.
Marty going by a ridiculous alias in each past time period, always someone far too notable in the present to be a watertight alias.
Marty's egotistic nature getting the better of him at the slightest hint of being called cowardly, always luring him into making a huge mistake. Thankfully, he gets over it. Ironically, his father starts off as timid until learning to be assertive, which later saves the McFly family from taking a lot of crap and going down the tubes. On the opposite end of things, Marty's future son is even more irrational and plucky, so the hot-blooded streak grows with each generation.
Say My Name: Doc and Marty do tons of this throughout the movies. And regardless of the decade, or even the century, Marty will be addressed by a Tannen with "HEY, MCFLY!!"
Even middle-aged Marty isn't free of this. He attempts to run a scam on his own company, only to find his irate boss lying in wait. "MACH FRY!!!"
Sci-Fi Writers Have No Sense of Scale: Time travel needs 1.21 gigawatts — the only source of which is supposedly plutonium or a lightning bolt. A lightning bolt actually generates three whole orders of magnitude more power, peaking at just over one terawatt, and a plutonium-powered fission reactor kinda wouldn't generate any power whatsoever.
Screw Destiny: Prevalent throughout the series as Marty and Doc change reality by time-traveling, but comes to a head two times. First, Doc, despite his misgivings, has his life saved - twice - by knowing how and when he is going to die, and Marty narrowly avoids a crippling accident that would change his life forever, thus changing the future they had just worked to save to the one we have now. At the very end of the trilogy, Doc says that it proves that there's no such thing as fate. Although the point about Marty avoiding his accident is less Screw Destiny and more learning a lesson while in the past/future and avoiding the situation on his own.
Scully Box: Because Christopher Lloyd is 6'1", much taller than the 5'4" Michael J. Fox, camera tricks were used to avoid using one. For example, the two are rarely in the same shot together and, when they are, one is usually sitting down or much closer to the camera than the other. When Doc Brown is talking, he's often moving around so much that the viewer can't really tell how tall he is. Lloyd also improvised a hunch in his posture that helped give the character more of a Mad Scientist look.
Two to Chitty Chitty Bang Bang: Doc owns dogs named after famous scientists (Copernicus in 1955, Einstein in 1985), just like how Caractacus Potts owns a dog named after a famous inventor (Edison). And they both make flying vehicles. The time machine train in Part III even sprouts wings like Chitty.
Another Chitty shout-out is how they both have breakfast-making machines in Part I and Part III.
It's best explained, as the filmmakers do, by paying careful attention to the Clocktower. In the original timeline the stone ledge under the clock is perfectly intact only for it to be broken when Doc climbs up there during the climax. The ledge is broken in all subsequent appearances. So yes, there was an original timeline that Marty erased through his actions in the past.
Stock Sound Effects: BTTF loves Castle Thunder, especially in the first two installments. It appears literally dozens of times, mixed in different ways, during the big Clock Tower Finale.
Take That: Biff Tannen and the Tannen family are named after then-Universal Studios executive Ned Tanen, who gave the Bobs a hard time during the making of their previous movie I Wanna Hold Your Hand.
That Was Not A Dream: Once in all three films. In each one Marty gets knocked out and comes to in a dark room being nursed to health by a woman he thinks is the mother he knows, believing his recent hardships were a nightmare. The woman inevitably reassures him in a way that tells Marty (and the audience) that it actually wasn't a dream.
Thermal Dissonance: The outer surface of the DeLorean comes out of a time jump extremely cold. If the air is humid, it promptly gets covered in ice.
Time Is Dangerous: The DeLorean has to be traveling at 88 miles per hour. Which means that unless you know what's going to be in front of you when you arrive in the new timeline, you're going to crash. By the third movie, Doc seems to be acknowledging this. Marty's a little less sure, but both times Doc assures him that the obstacle he's seeing in the present won't be there in the destination time.
Time Travel for Fun and Profit: Doc is the former, Marty and Biff seem to be the latter. Though Marty quickly gives up on the latter after Doc catches him red-handed and sermonizes him.
Title Drop: It's done several times throughout the course of the trilogy. In fact, it's become so common for Doc and/or Marty to drop the title that it's practically become a Catchphrase / Borrowed Catchphrase.
Toxic Friend Influence: Marty's "friend" Needles. Pretty much everything bad that happened to Marty in the original future was because of him. Although it's never stated that they're friends.
Two-Part Trilogy: Although the first movie ends on a definite Sequel Hook, it can be clearly be enjoyed by itself. The second, however, ends on a clear Cliff Hanger that obviously requires a third movie in order to be resolved. Marty's "chicken" problem was also added for the sequels, as well as nemesis Douglas "Flea" Needles. Justified in that the second and third part were originally intended to be a single movie, titled Paradox. And even after the split, they were still filmed back-to-back.
Story-wise, however, it is somewhat of an inversion, as Part II & III are both quite distinct from each other. Part II (especially during the second half) ties in strongly with the first film, while Part III is more or less a separate story that just uses the events of the previous films to get things going.
Vague Age: Doc's age in 1955 and 1985 is never mentioned in the films. The fact that Christopher Lloyd looks exactly the same in both time frames doesn't help. He must be in his 80s in 1985.
Fairly hilarious in that his age is referenced in Part II (with his "old" mask removal and his comments about having work done), so he didn't have to wear makeup. Yes, he really was given an age-up for the original 1985. Lloyd just has that old puppy dog face no matter what his age, apparently.
In Back to the Future: The Game, they go to the year 1931, and Marty meets a very young Emmett Brown (not even Doc Brown yet, as he hasn't got any kind of degree). Emmett confirms to Marty that he is, in fact, 18 years old. Do the math, and you see he was born in 1913. This makes him 42 in 1955 and 72 in 1985. There. You can stop losing sleep at night over this now.
Villain Decay: Actually invoked with Biff. In the first film, he goes from being George McFly's bullying co-worker to the family's submissive mechanic, all because of George's punch in the 1950s. He got worse in the sequel but went back to being subservient by the end of the third movie.
Writers Cannot Do Math: A stock DeLorean DMC-12 only got about 130 horsepower. It would go 0-60 in about a day and a half. That, of course, is before you dump a fusion reactor in the back seat, with the requisite lead shielding to keep everyone inside from dying of a radiation overdose, easily doubling the weight of the car. So the notion that the car ever got up to 88 is hilarious.
Aluminum Christmas Trees: In-universe. 50s Doc initially takes this approach towards a Reagan Presidency, but comes around to it when he sees Marty's portable television studio (read: a camcorder), realizing that the President has to look good on TV.
As Marty tries to tell George to ask Lorraine to the dance, George objects by saying it would mean missing his favorite TV show Science Fiction Theatre. Science Fiction Theatre was an actual sci-fi show from the 50s, a spiritual predecessor to The Outer Limits and The Twilight Zone (in the extended version of the "Darth Vader" scene, Marty also name-drops those shows).
Auto Erotica: Marty's plan to get his parents together involves George finding him "parking" with Lorraine and trying to take advantage of her, then pulling him out of the car and pretending to beat him up to make him look like he's the tougher guy. Except Biff turns up instead of George, and he wants revenge on Marty for the $300 damages his car took in the manure truck incident, so he decides to attempt to molest Lorraine. Hence, George's "rescuing" Lorraine ends up becoming the real deal.
Then again, Lorraine seems like she may or may not be trying to get someone else in the backseat before Biff shows up. Specifically, Marty.
Been There, Shaped History: Back in 1955, Marty McFly plays Chuck Berry's Johnny B. Goode when he steps in for Chuck's cousin, Marvin Berry. While Marty is playing, Marvin calls Chuck up so he can listen in on this "new sound." He also gives the 1985 mayor Goldie Wilson, at that time the black janitor in the malt shop, political aspirations the exact year the Civil Rights Movement started.
The Big Damn Kiss: George and Lorraine at the dance, complete with "Earth Angel" swelling on the soundtrack, and saving their son's entire existence.
Big "NO!": Marty after Doc is shot by the Libyans.
Blatant Lies: Lorraine says to Marty that she never went chasing after boys. When we see her younger self, it turns out that she is instantly enamored with George and, due to Marty taking his dad's place due to an accident, all but attempts to force herself on him.
Borrowed Catchphrase: "If you put your mind to it, you can accomplish anything." Doc never actually says it in the movie (or the rest of the trilogy), but Jennifer attributes it to him. Only Marty and George ever say it — in fact, it seems that George has adopted it as his own catchphrase at the end of the movie.
Brother-Sister Incest: Invoked. Lorraine is coming hard onto Marty, kissing him back into a corner, and it suddenly occurs to her that it's like kissing her brother. She is Squicked, although not nearly as much as Marty is, knowing that it's really Parental Incest.
Celebrity Paradox: Huey Lewis exists in the BTTF universe, as proven by Marty's posters in his room — and so does the audition judge, played by... Huey Lewis. Even better: at the end of the movie, Marty's clock radio plays "Back in Time" by Huey Lewis and the News. The song was specifically written for (and contains a TON of references to) a little movie called Back to the Future.
At the start of the film, Marty is conveniently given a flyer by a woman who (along with other volunteers) is attempting to raise money to save the historic clock tower. The scene is played for laughs, but the flier contains crucial information on how to return to the future, including the exact date and time that the clock tower was struck by lightning.
Lorraine tells the kids that if her father hadn't hit George McFly with his car in 1955 before the dance, none of the kids would've been born. She also says that she and George fell in love after they had their first kiss at the dance. It's all seemingly useless information that parents just say for no reason, right?
When Marty hides the DeLorean shortly after arriving in 1955, he is shown putting the walkman he later uses as part of his alien impersonation in the car for no other reason than to establish he has it.
Chekhov's Gunman: Dixon, the guy who cuts in on George and Lorraine at the dance, was previously seen kicking George around when he had the "Kick Me" sign on his back.
Chewing the Scenery: Surprisingly, Marty - near the end of "Johnny B. Goode". His faces while he goes over-the-top are hysterical.
Clean Up The Town: Goldie Wilson, in 1955 a busboy at Lou's Diner, imagines himself as doing this after Marty recognizes him as the future mayor and tells him that. Lou hands him a broom and tells him he can start by sweeping the floor.
Marty is at Doc Brown's house, and thinks he will be on time for school, only to discover all his clocks are twenty-five minutes slow.
Doc Brown proves to Marty that the time machine works by syncronizing watches with a digital clock he attaches to his dog, then sending the dog one minute into the future. When the dog shows up again, his clock is a minute slower than Doc's.
Clown Car: Biff's goons make the mistake of insulting one of The Starlighters outside his Cadillac, causing four others to exit the car.
Comically Missing the Point: Played with, perhaps. It initially sounds as if Marty is amazed by the time machine. Then he adds the phrase, "out of a DeLorean?!"
Marty McFly: Are you telling me you built a time machine... out of a DeLorean?!
In 1955, when Marty tells Doc who he is while using the mind-reader:
Marty: Doc, I'm from the future. I came here in a time machine that you invented, and I need your help getting back to the year 1985.
Doc: My God... Do you know what this means? It means that this damn thing doesn't work at all!
Common Knowledge: In-universe example, when Doc Brown is showing Marty how to set the target date on the time machine:
Doc Brown: Say you wanted to see the signing of the Declaration of Independence." (sets date to JUL 04 1776)
The Declaration was not signed on this date.
Doc Brown: Or witness the birth of Christ!" (sets date to DEC 25 0000)
Jesus would not have been born in December. Plus "0000" isn't even a year on any calendar (the year before AD 1 was 1 BC). Both of these were intended as jokesby the filmmakers who knew full well that neither of these dates were accurate. Nobody got it.
Contrived Clumsiness: Marty "accidentally" trips Biff when they're in the diner in 1955 Hill Valley.
Damsel in Distress: Invoked and then played straight — Marty's plan is to stage an Attempted Rape of Lorraine (his own mother) so that George can intervene and win Lorraine's affections. However, when Biff interrupts the staged attempted rape and tries to actually rape Lorraine, it's up to George to save the day, which he does, achieving the desired result.
Easily Forgiven: While Biff in the altered timeline appears to have become a harmless, eager-to-please Gentle Giant who is barely recognisable as the bully he used to be, both George and Lorraine seem to be remarkably grudge-free about him trying to rape Lorraine.
Eating Lunch Alone: George in 1955 tends to eat by himself in the cafeteria and focus on writing his ideas for a science fiction book down on paper.
Engineered Heroics: Subverted: Marty's plan to get George and Lorraine together goes wrong, requiring George to be a real hero.
In the novelization, George worries that Biff was in on the plan and had faked being knocked out, until Marty confirms that Biff was serious.
Everything's Better With Cows: After Marty ends up in 1955, he runs into a scarecrow, then crashes into the barn where Old Man Peabody's cows reside.
Exact Words: George won't try to ask Lorraine to the dance, telling Marty "neither you nor anybody else on this planet is going to make me change my mind." So that night, Marty pretends to be "Darth Vader, an extra-terrestrial from the planet Vulcan".
First Kiss: George and Lorraine have theirs during the Enchantment Under The Sea Dance, while the band plays "Earth Angel".
555: Doc Brown's phone number, as well as Jennifer's grandmother's.
Florence Nightingale Effect: Discussed Trope. How Marty's mother fell in love with his father... and how Marty accidentally ends up replacing his father in her affections. Squicks Marty, repelling him, and inadvertently making him even more attractive to her. Especially after he defends her from Biff in the school lunch room. Lampshaded by Doc.
Biff, when he sits at Lorraine's table and tries to grope her: "You want it, you know you want it, and you know you want me to give it to you."
During the scene where Marty and George are going over the plan of how they're going to get George with Lorraine we have this exchange while George is doing his family's laundry:
Marty: Because George (voice begins to stutter) Nice girls get angry when not-nice guys take advantage of them. George: Hoh! You mean you're going to touch her on her— (holding a bra in his hand)
When Strickland gives Jennifer her tardy slip, she holds it up between them, her middle finger very prominent.
God Guise: Marty uses his radiation suit and Walkman stereo to dress up as "Darth Vader from the Planet Vulcan". He frightens George and threatens to melt his brain if he doesn't take Lorraine to the school dance.
Grumpy Old Man: Sam Baines really isn't that happy with Marty jumping in front of his car.
Here We Go Again: The ending was supposed to this trope as they'd never planned any sequels. The film's main problem (that Marty accidentally erased himself from history) resulted because he used the time machine; just when everything is perfect, Doc arrives and whisks them off in it again.
Heroic Sacrifice: Doc draws the Libyans' attention to give Marty time to run, and gets shot for it.
Improvised Lightning Rod: Doc Brown uses the Clock Tower as a lightning rod to gain the 1.21 gigawatts of electricity the DeLorean needs to get back to the future.
Improvised Zipline: Doc Brown uses the heavy duty electrical cable attached to the clock tower as a line to reach the ground quickly and fix a break in the line.
Incest Is Relative: Parodied, in that whilst Marty knows who Lorraine really is, she has no idea as to his true identity. Luckily for Marty, Lorraine likens kissing him to kissing her brother.
In Spite of a Nail: Played with. The new 1985 is identical in most respects... but not entirely. The McFly family turned out differently, Biff Tannen turned out differently, Hill Valley's shopping is now done at the Lone Pine Mall, and of course, Chuck Berry got the idea for "Johnny B. Goode" from a sample he overheard during a telephone call from his cousin Marvin.
Just Keep Driving: Used as a one-off joke when Marty escapes Old Man Peabody's farm and steps on the entrance to the construction site for Lyons Estate (which is breaking ground next winter). After attempting to ask a passing middle-aged couple where he was, the woman starts to freak, tapping her husband rapidly on the shoulder and yelling "DON'T STOP OR WE'REDEAAAADDD!!!" Marty then has to use the billboard advertising the new development to hide the DeLorean.
Kid from the Future: Marty, although his parents know nothing of who he really is. Lorraine is enamoured with him due to his cavalier attitude (and the "Florence Nightingale effect") and George initially thinks he's a pushy pest who keeps following him around.
Let's Get Dangerous: Bumbling fretful Doc, when he sees that he accidentally unplugged the other end of the cable, sucks it up, and ziplines off the clock tower in the middle of a storm.
Letting the Air out of the Band: Happens the minute Biff angrily marches in to throw George out of the diner. Apparently, someone in the room had a good sense of dramatic tension to unplug the jukebox at that exact moment.
Limit Break: George punching out Biff after Biff laughs at him and pushes Lorraine to the ground.
Looping Lines: Crispin Glover (George Mc Fly) lost his voice due to nervousness while filming Back to the Future. For some scenes, he had to silently mouth his lines, with his voice being dubbed in later at a recording studio.
Manly Tears: Marty towards the end of the movie. After seeing his friend, Doc, killed once, Marty is now praying that Doc read his letter and took precautions so he wouldn't be killed a second time. Marty arrives just in time to see the Libyans shoot Doc again. Running over to him, Mary finds Doc unconscious. Assuming the worst, he begins sobbing. However, we find out that Doc is fine. Marty's tears of sadness soon turn to tears of joy.
Meaningful Echo: The instance here is George and Biff's conversation after Biff wrecks a car George loaned him:
Biff Tannen:(playing George's head like a bongo) Hello? HELLOOOOOO? Anybody home? Think, McFly! Think! I've gotta have time to get 'em retyped. Do you realize what would happen if I hand in my reports in your handwriting? I'll get fired. You wouldn't want that to happen, would ya? [pulls on George's tie] Would ya?
George McFly: Well no, of course not, Biff. I wouldn't want that to happen. [Biff helps himself to some gumballs] Now look, I'll uh, finish those reports on up tonight, and I'll run 'em on over first thing tomorrow. All right?
Biff Tannen: Not too early. I sleep in Saturday.
Likewise, Marty walks into Lou's Diner and after Lou hands him a cup of coffee, the camera pans to show that Marty is sitting next to George, who is occupied eating his breakfast. Suddenly the doors fly open:
Biff Tannen:(again with the head-battering) Hello? HELLOOOOOO? Anybody home?! Think, McFly! Think! I gotta have time to recopy it. Do you realize what would happen if I hand in my homework in your handwriting? I'll get kicked out of school. You wouldn't want that to happen, would ya? [George hesitates. Biff grabs George by his shirt] Would ya?
George McFly: Well no, of course not, Biff, I wouldn't want that to happen... I'll, uh, finish that on up tonight and then I'll, uh, bring it over first thing tomorrow morning.
Biff Tannen: Not too early. I sleep in Sunday.
Meet Cute: George and Lorraine's first meeting, the way it originally happened.
Moment Killer: Marty and Jennifer are playfully flirting in the courthouse square, and are an inch away from kissing...when they are interrupted by: "Save the clocktower! Save the clocktower!", complete with the lady shaking the donations tin in their faces. So much for that moment....
And as George is stumbling his way in wooing Lorraine at the cafe, it seemed like he'd succeed until Biff showed up.
Mundane Made Awesome: George's method of ordering a milk....chocolate. The outtake is even better, where the milkshake glass bounces off George's hand and crashes to the floor.
Marty setting fire to the living room rug at the age of eight.
Also, it's briefly implied that Marty and George McFly aren't the first victims of a Sam Baines hit-and-run accident, given that the moment George rides away on his bike, Sam shouts, "Stella! Another one of these damn kids jumped in front of my car! Come on out here and help me bring him in the house!"
When Marty arrives in the 1955 town square, we can see some of the things that have and haven't changed since then. The Texaco station has a team of four uniformed men to service cars, including filling the tank and polishing the engine. Also, much like the 1985 town square has a mayoral campaign van going around blaring "Re-elect Mayor Goldie Wilson!" on loudspeakers, the 1955 version of this scene has a car blaring "Re-elect Mayor Red Thomas!" on loudspeakers, even decked out with similar looking signs.
Parental Bonus: After Marty wakes up from being hit by Lorraine's father's car, Lorraine tells him that his pants are "over there... on my hope chest". Many people who were born after the 1950s may not understand what a hope chest is. It's a chest that young girls used to keep in preparation for their marriage. In other words, Lorraine is already fantasizing about marrying the young man that she does not realize is her future son. One assumes that in the original timeline, this also happened with George.
Parental Incest: Marty seriously tries to avert this trope, and does everything wrong until the night of the party; everything he does only makes him more attractive to her. He jumps and flees when she makes a pass at him, defends her from Biff's "meat hooks", trips up Biff when Biff goes after George, and leads Biff on an over-the-top skateboard chase culminating in Biff's comeuppance in manure. By this time, she really wants to get to know him.
The Peeping Tom: The then-teenage George McFly spies Lorraine undressing from a tree next to her window. This becomes a crucial plot point as this is the point where Marty alters history. When George falls out of the tree, Marty pushes him out of the way of an oncoming car... accidentally preventing his parents' original meeting. For an idea of how it originally happened, imagine Marty's actions that night at the dinner table with George in place of Marty.
Pet's Homage Name: Doc's dogs. His 1985 dog is named Einstein, his 1955 dog is Copernicus.
Police Are Useless: Aside from Attempted Rape above, Biff in 1955 also makes multiple threats of assault throughout the movie, and in one scene attempts to commit MURDER, and nobody even seems to think that he's doing anything illegal.
The Power of Rock: Played with. Marty's rendition of "Johnny B. Goode" impresses everybody until he gets carried away with his guitar solos.
Marty: I guess you guys aren't ready for that yet... but your kids are gonna love it.
Reliably Unreliable Guns: Marty is saved repeatedly from being shot by Libyans because their rifle jams. They are shooting an AK-47, which are famed for their reliability even under the harshest conditions. However, we do see them simply trying to clear the jam rather than abandoning the gun immediately.
Running Gag: People mistaking Marty's down jacket as a "life preserver" - the guy behind the counter at the malt shop, or Lorraine's mother.
Lorraine keeps calling Marty "Calvin Klein", even after Marty corrects her.
Scary Black Men: "Who you callin' "spook", peckerwood?!" Biff's gang seems more afraid of the copious amount of pot smoke billowing out of the car than anything else: "I don't wanna mess with no reefer addicts!"
Shared Family Quirks: Marty sits in a diner and nervously rubs the back of his head in disbelief that he's in the past, and the camera pans to show he's sitting next to George, who is doing the exact same thing.
Spear Carrier: The couple at the dance amazed at George standing up for himself.
Stopped Clock: The clock tower stopped after being stuck by lightning, giving Marty and Doc a precise time to use the lightning to time travel.
Sweet and Sour Grapes: Towards the beginning, Marty admires a pickup truck, wondering what it'd be like if he had it. When he comes back from 1955, he discovers he has that truck (or another truck like it).
Doc declares he has to send Marty "Back! To the future!"
And again at the end of the movie when Doc comes back from 2015, to pick up Einstein and go back to... you know.
Took a Level in Badass: George standing up to Biff is a critical moment that fills him with self-confidence and changes the destiny of his whole life and family.
Turn Out Like His Father: Played with in every possible way. People, especially Strickland, tell Marty he's going to be a loser like his dad, then the past changes and his dad is not a loser but Marty is still destined to be a loser, then that future is possibly avoided presumably letting Marty succeed at a creative pursuit like his dad.
Vanity License Plate: The DeLorean has the tags OUTATIME. And really crappy screws holding it on the back of the DeLorean , because of its habit of popping off and pirouetting on a corner.
After the first plate falls off, Doc Brown goes into the future and replaces it with a 2015 barcode license plate with enough bars to spell "OUTTATIME", inserting another "T". That one also falls off when the entire car is pulverized by a freight train, and does its little pirouette trick again, likely the only bit of the car that survived the collision intact.
The Libyans. They come charging in, shooting at Doc Brown from the van, they hit a kiosk and the van tips over. Then Marty, Doc, and the film forget about them completely, even having a joyful reunion at the end without bothering to see what's going on with the homicidally angry terrorists in the van a few yards away.
Since said van was travelling at around 80mph when it hit the kiosk, it's probably a safe assumption that the Libyans are at the very least unconscious, and more likely dead.
What happened to Doc Brown's remaining plutonium? Did he use it all before fitting Mr. Fusion, or did he just throw it in a bin somewhere? (Which, given the general recklessness he displays during the trilogy, is not that much of a stretch.)
Who's on First?: Marty's attempts to get a Tab, and then a Pepsi Free, at Lou's Cafe in the 50's.
Lou: You want a Pepsi, pal, you're gonna have to pay for it!
You Keep Using That Word: At least from 1955!Doc's point of view, as he thinks that Marty's use of the word "heavy" still applies to weight and measurements, when, from Marty's point of view, he's just using the slang term for something that has a deep, powerful impact, whether philosophical, intellectual, or emotional.
Abusive Parents: Biff-A is really abusive, not just to Lorraine, but also to Marty. Lorraine's line "They must have hit you over the head hard this time..." after Biff's tirade implies that Marty-A gets hit over the head a lot.
Acting for Two: Michael J. Fox is acting for at least five: Marty 1985, Marty 2015, Marty Jr., Marlene, and Marty 1955. Meanwhile, Thomas F. Wilson plays 1985 Biff (both universes), 2015 Biff, Griff, and 1955 Biff.
And Your Little Dog Too: Biff-A to Lorraine-A, in 1985-A, threatens to put Dave and Marty in jail if she walks away from him, just like jailbird Joey (who apparently is the one thing in the timeline that hasn't changed).
Angry Black Man: The dad of the family living in Marty's house in the alternate 1985. To be fair, he did catch Marty breaking into his daughter's room, so the anger was justified. His wielding a bat made him into a Scary Black Man.
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.)
The Apunkalypse: Not directly employed, but the inspiration behind Griff's gang in the future.
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
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.
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!
Bizarro Universe / Crapsack World: 1985-A. Hill Valley was reduced to the armpit of the west coast an,d as mentioned above, Biff's political clout kept Richard Nixon in office for fifteen years..
Balls of Steel: There is a clang when Marty punches Griff in the groin. Subverted in that he feels the blow.
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 home in 1985-A, he discovers that his family doesn't live there in this timeline. Since his room is now occupied by a young girl, her father rushes in, wielding a baseball bat, and drives Marty out.
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 to get breast implants. Even Marty is alarmed.
Briefcase Full of Money: Upon returning to 1955, Doc unveils a silver attache 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.
Can't Get Away with Nuthin' : It takes four seconds for Future Marty's boss to send him the "YOU'RE FIRED!!!" faxes after Marty engages in an illegal business deal with Needles.
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.
Chalk Outline: In 1985-A, Marty comes across the outlines of two drive-by shooting victims shortly after he is chased out of his 1985 house by the black family that resides there in this timeline.
Chekhov's Gun: In 1985, Biff tries to give Marty a new matchbook for his company when Marty leaves. Later, in 1985-A, Marty takes a matchbox from Biff-A's office, and after destroying Grey's Sports Almanac, he sees its writing change from "Pleasure Paradise" to "Auto Detailing"
Click Hello: Mr. Strickland thinks Marty's the son-of-a-bitch who's been stealing his newspapers from his porch.
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.
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.
Domestic Abuse: To no one's surprise, Alternate Universe-Biff is a philander who's grown bored of Lorraine, keeping her around only a Trophy Wife and symbol of his victory over George. Marty goes berserk when Biff shoves her to the ground, earning a punch in the gut. That's right, Biff even slugs his adopted children.
Dramatic Irony: In alternate 1985, it is established that Lorraine ends up 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!"
Drowning My Sorrows: Lorraine-A is a bigger alcoholic than in the first 1985 from the first film.
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.
Evil Tower of Ominousness: Alt-Biff 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.
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 hairgel while Marty wasn't.
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.
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 time Marty catches up with Doc in the third part of the trilogy, he had already been there for nine 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", 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 bullet-proof vest! Ingenious!" Guess how the showdown in III is resolved?
Doc tells Marty that his visit to the rejuvenation clinic "added a good 30-40 years" to his life, ensuring that he can start a family with Clara and be around long enough to see their sons grow up in Part III.
Doc: Something inconspicuous! (cut to Marty wearing a not-so-inconspicuous leather jacket, hat, and shades)
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.
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.
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, Doc lies about Marty and Jennifer not being "assholes in the future." When the scene was reshot for the start of the second film, Doc hesitates before answering their question.
History Marches On: The USA Today paper reporting on Marty Jr.'s arrest also reports that "Queen Diana" is scheduled to visit Washington, D.C. Of course, Diana tragically never lived to see 2015, let alone become queen.
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.
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.
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, and Lorraine's brother Joey still turns out to be a jailbird.
Insult to Rocks: Marty comparing 1985-A with Hell. Doc retorts he's not giving Hell enough credit.
I Own This Town: A filthy rich Biff has corrupted Hell Valley and is now its overlord.
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 at 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.
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...From the perspective of reality in The New Tens, this stuff had better get a move on, though as the Zee Rust entry below shows, they were deliberately going overboard with this stuff.
So help them though Nike seems pretty determined to get those self-lacing shoes out by 2015.
On the other hand, of course... Glasses that project digital data directly into your eyes, widescreen/flatscreen TVs, video calls, people sharing ridiculous trivia about themselves via electronic media, videogames you don't need to touch to play... some of the crazier predictions were right.
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.
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.
Manly Tears: Marty when he finds his father's grave in the alternative 1985 timeline. 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.
Mean Boss: Ito T. "Jitz" Fujitsu. In fairness, he had good reason for firing Marty, but he made no indication of coming down as hard on Needles.
Meaningful Echo: The confrontation between Marty and Biff in the tunnel, with Marty trying to use his hoverboard 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.
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.
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.
The Lorraine of 1985-A was modeled after various female televangelists of the 80s, particularly Tammy Fae Meissner (aka Tammy Fae Bakker).
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".
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.
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 led down the courthouse steps to a police car in handcuffs as a USA Today camera is lowered from the sky. Griff shouts, "I was framed!" at which point the camera snaps his picture.
Revolvers Are Just Better: Biff's snub revolver. Handy for silencing environmental activists, pulp sci-fi authors, and meddling kids.
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." Well, to be fair, the very first thing he has to say is, "AAAAAAAAHHHH!"
Sean Connery Is About to Shoot You: Taken to a whole new level by the animated holographic advertisement for Jaws19 (this time, it's really really personal) that Marty encounters, in-which a shark eats you.
Many references to It's a Wonderful Life during the 1985-A sequence. Hill Valley is a not-so-subtle reference to Pottersville, with Biff in the role of Potter.
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 forshadowing, as the Vietnam War is still grinding on in a dystopian Biffverse.
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.
It's true that nobody really knew what CPR was until roughly two years later.

Signs of Disrepair: In 2015, Hilldale's sign has gotten vandalized from "The Address of Success" to "The Address of Suckers". In 1985-A, the "Welcome to Hill Valley" sign says "Hell Valley" instead.
The Smurfette Principle: Jennifer Parker. Robert Zemeckis and Bob Gale say that had they 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, in the second film, she's sedated less then five minutes in and pretty much spends the rest of the series that way.
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.
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, so the Doc is quite accurate with his observation.
Surprisingly, repairs on a DeLorean with a door-ding or other simple dent would actually be cheaper than a dent in the same spot on Biff's car ($300 in 1955 US dollars you'll remember him complaining about) adjusted for inflation. With the vast majority of cars, body-panels are welded to the frame. On a DeLorean, they're bolted on, which makes replacement relatively easy.
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, mocks them and then throws it onto a second story balcony. The kids stand there, crestfallen, as Biff walks away while cackling to himself(!).
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 III. Thanks for the Spoiler Alert, Zemeckis. Deliberately done 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.
Trailers Always Spoil: The preview for Part III includes a shot revealing that Marty (still in his cowboy gear) eventually gets back to Jennifer, which is one of the trilogy's major subplots.
Trophy Wife: Marty's mother has been coerced into becoming Biff Tannen's trophy wife, complete with unwanted breast augmentation.
Two Decades Behind: Invoked and parodied with Gale/Zemeckis' "user-friendly" 2015 A.D. The fashions of the era reflect the 80's at their pastel, animal print and peroxide worst. Kids still wear acid-washed jeans (albeit 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.
Unintentional Period Piece: A weird case; the Cafe 80's scene, (remember, 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 were not done very well."
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.
Vice City: 1985-A. Marty's old neighborhood is now a ghetto overrun by wild dog packs(!). The city 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 as of 2012, it's provided courtesy of Skype.
What, Exactly, Is His Job?: 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.
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, and 1955 Biff.
Even though Doc's copy of USA Today is a localized edition (the joke seems to be that they took over the whole newspaper industry), "Youth Jailed" is not exactly cover story material. Especially when you see the other stories from that day.
Similarly, though perhaps less severe, later in the movie we see the papers from the alternate timeline where "Hill Valley Man Wins Big at Races" is the main headline on a 1958 copy of the local paper, over "Khrushchev Becomes New Soviet Premier." In the same scene we also see that "Emmett Brown Committed" has pushed a story about Nixon running for office for a Fifth time (!!) and vowing to end the Vietnam War. It seems the local press in Hill Valley really doesn't care for anything going on beyond their little town! Truth in Television: a lot of small-town newspapers are like this.
Zeerust / Twenty Minutes into the Future: 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.)
Ironically, some of their predictions 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.)
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)
Enforced by Major League Baseball- they could have sent the Miami Marlins to the American League, potentially setting up a Cubs-Marlins World Series in 2015, but instead chose to send the Houston Astros to the AL.
The idea of a robot dogwalker (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.
Action Film, Quiet Drama Scene: The scene in the saloon towards the end, which you could compare to High Noon. Buford and his gang have Marty trapped, and Buford is counting down to a showdown. Doc is unconscious. Marty is visibly struggling with whether or not to fight Buford, as Seamus looks on.
Amplified Animal Aptitude: Doc's dog Copernicus seems to at an almost human level of intelligence at times. For starters, after Doc finishes reading the letter that his future self wrote to Marty, Copernicus seems to be rather sad about Doc being Trapped in the Past. In addition, Copernicus is the one who discovers Doc's tombstone, and he seems to realize what it says.
Bag of Spilling: The DeLorean lost its flying abilities when it was struck by lightning in the last movie.
Bears Are Bad News: A black bear happens to be lying in the cave Marty hides the DeLorean in.
Becoming the Mask: Doc tells Marty in his letter that he'd set himself up as a blacksmith as a cover while attempting to fix the DeLorean. But when he realized the damage was beyond the capacity of 1885 technology, he buried the time machine so that Marty could fix it with the help of his 1955 counterpart and go back to 1985 himself, and accepted his place as a blacksmith, content to stay in 1885.
Do not call Buford Tannen "Mad Dog." It's clear that this button has been around for a while, as the moment Marty calls him "Mad Dog", every single patron and bartender hides or silently runs away.
Buford: Mad Dog?! I hate that name! I hate it, you hear?! NOBODY calls me Mad Dog! 'Specially not some duded-up, egg-suckin' GUTTERTRASH!
Don't hurt Marty in front of Doc or especially Doc in front of Marty. If you have, don't laugh about it.
Finally, don't suggest assaulting Clara in front of Doc. Not that you'll get off easily if only she hears it.
Big Damn Heroes: Marty defeats Buford Just in Time to stop him executing Doc; meanwhile, Doc swoops in Just in Time to save Marty from getting hanged AND Clara from falling. Lampshaded by Marty: "Why do we have to cut these things so damn close?"
Bittersweet Ending: Averted. Initially, it looks like a Bittersweet Ending because Doc Brown is stuck in the 1800s, but he is with the woman he loves, and Marty is reunited with Jennifer in his own time, but it looks like he will never see Doc Brown again. However, they are reunited in the end anyway because the Doc builds a steam-powered train time machine.
The Blacksmith: Doc sets himself up as one when trying to repair the DeLorean until giving up and hiding it in the Delgado Mine. By the time Marty comes to 1885 to rescue Doc, he's still operating as a blacksmith.
Bullet Dancing: Spoofed, as Marty turns this into the Moon Walk. And it is awesome. Buford and his gang are so dumbfounded that they just watch in disbelief. Then he hits Buford with a spittoon, and all hell breaks loose.
Curb-Stomp Battle: Marty vs. Buford. The only punch Buford lands on Marty after he gets up from Faking the Dead ends in Buford clutching his knuckles. Marty, on the other hand, pummels him silly.
Dare to Be Badass: The saloon regulars try to give one to Marty, saying he'll be labeled a coward for the rest of his life if he doesn't duel with Buford, though mostly because they're betting on the outcome one way or another.
"'Shot in the back by Buford Tannen over a matter of 80 dollars?!' What kind of a future do you call that?!" However considering that this is 1885, and taking inflation into account, 80 dollars would have likely then been considered a big deal.
Dub-Induced Plot Hole: Not exactly a plot hole per-se, but Doc's last line "Already been there (the future)" is sometimes dubbed to "I already am in the future." The original line is meant to be the lead-up for the Time Train's flying capability. The dubbed line turns it to a character moment, showing that whenever he can go, his heart is still in the Old West. Both versions work in their own way, though the dubbed version makes the train's flight something of an Ass Pull.
Dude, She's Like in a Coma: Played to be romantic rather than creepy. When Marty gets back to 1985, he sets out to Jennifer's house to check if she's alright from the events of Part II, and finds her asleep on her front porch. After trying and failing to wake her the old-fashioned way, he kisses her on the lips, where-upon she kisses him back then wakes up. This could also count as a Reunion Kiss.
Early in the film, Doc, confused on who "Clara" is, denies to Marty that he knows that any woman by that name and dismisses the notion of love at first sight as "utter romantic nonsense". Then the Hill Valley 1885 mayor rolls in and talks to Doc, reminding him that at a town hall meeting he agreed to meet the new schoolteacher. Doc breezes over a majority of the details, until the mayor mentions her name, "Clara Clayton", to which Doc freezes in horror and gives the same Oh Crap face previously used for comedy a more serious twist.
When Marty is reunited with Doc, who is currently talking down Buford, they are discussing about a recent shoeing job done on one of Buford's horse's that, because it went afoul, Buford thinks Doc should be held responsible. When Buford mentions the prices of the new horse and whiskey he bought that day, "$75 for the horse, $5 for the whiskey", Marty quickly does the math and whispers in shock, "That's the eighty dollars!" note (According to the tombstone Marty found, Doc was "shot in the back by Buford Tannen over a matter of eighty dollars.")
When Needles challenges Marty to a race near the end, we are given two shots of Marty shifting gears in his truck. First, he moves the gearshift selector to the far left and up for 1st gear. Then, we see him shift again all the way right and down, for Reverse.
Clara Clayton actually appears in the scene immediately before her introduction. If you pay very close attention to the background when Marty and Doc are at the train station looking at the map of the track leading to Shonash Ravine, but especially when Marty says "Doc, according to this map, there is no bridge", as can be inferred if you pay close attention to her hat and her dress, though her back is to the camera so we can't see her face.
Also in that scene, the (then-)brand new clock shows the time around 10:04, which is when it will stop in 1955.
Before going to 1885, Marty complains that Clint Eastwood never wore such a ridiculous getup, and Doc doesn't know who that is. They have this conversation in front of a drive-in theater, in front of a poster for Revenge of the Creature, Eastwood's first film.
When Doc and Clara return in the time machine train, Doc in the foreground tells Marty and Jennifer to make their future a good one. In the background, for whatever reason, the child playing Verne motions towards the camera and points to his crotch. It's been hypothesized that the child actor was trying to signal to someone (possibly director Zemeckis) that he needed to pee.
Get Thee to a Nunnery: Ever wonder why Buford Tannen kept referring to Marty as "dude"? During that time period, "dude" basically meant City Mouse (hence, a "dude ranch" is a ranch for "dudes", i.e. tourists). Considering Marty is from The Eighties, it's odd that he doesn't lampshade how that word changed.
Going Native: Doc has adjusted to life in 1885 very well. Although, he did say that the Old West was his favorite time period.
Greek Chorus: The three old-timers who hang out at the saloon.
I Take Offense to That Last One: When Seamus asks Marty how he could travel through the Old West without a horse, boots, or even a hat, Marty answers "Well, my car—horse broke down, a bear ate my boots, and I guess I forgot my hat.", prompting Maggie to ask "How can you forget a thing like your hat?!". Also a case of Values Dissonance, as a hat was an integral part of a man's wardrobe at the time.
In Spite of a Nail: Again, the new timeline has barely changed toward the end, except that the ravine the train is supposed to cross over is originally called "Shonash Ravine" but was supposedly called "Clayton Ravine" after Clara fell in it (which Marty and Doc stopped from happening). After the train crashes into the ravine and Marty goes home at the end, the DeLorean rolls along the tracks and past a sign that says "Eastwood Ravine". Marty was going by Clint Eastwood in 1885, so "Clint Eastwood" fell into the ravine instead.
Instant Death Bullet: Subverted. Marty and Doc both assumed that Doc will be shot on Monday, because that's when he dies. Turns out he got shot on Saturday in the original timeline, and didn't succumb to his wound for another two days.
Instant Sedation: We find out Doc reallyCan't Hold His Liquor when he swallows a shot of whiskey and instantly passes out - the whiskey has barely gotten in his stomach, much less into his bloodstream or brain to have any effect.
In the Back: Is where Buford Tannen is supposed to kill Doc.
Irony: In 1985-A, Biff idolizes Clint Eastwood. In 1885, Buford thinks the name is utterly ridiculous and doesn't hesitate to call "Eastwood" a yellow-belly and kill him on sight.
In addition, when Marty is preparing to go back in time at a movie theater, he is afraid that he'll crash into the painting of a group of Indians underneath the screen. Doc reassures him that when he goes back in time, the theater won't have been built yet and the Indians won't be there. As soon as he arrives in 1885 however, he nearly crashes into a group of very real Indians who just happened to be riding through the area at the time.
Laser-Guided Karma: Buford had killed Doc because his horse threw the shoe Doc put on, throwing himself off in the process. But as Doc points out, Buford never paid him for the job, "So I say that makes us even!"
Like Parent, Like Spouse: The "Bobs" (Zemeckis and Gale) claim that McFly men are attracted to women who look like Lea Thompson, to explain why Marty's paternal great-great-grandmother looks so much like his mother. In addition, when you look at them, Claudia Wells (and later, Elizabeth Shue) both look a bit like Lea Thompson.
Logo Joke: Old Universal logos appear during the opening, in honor of the 75th anniversary of Universal Pictures Film Company, Inc. and the new logo being introduced for it.
Love at First Sight: Doc and Clara, though Doc's skeptical before they meet when Marty says that this happened with him and Jennifer.
Lyrical Dissonance: An odd example, considering you don't actually hear the words to the song, but the first song played at the hoedown is an uptempo version of "Nearer, My God, to Thee" of Titanic infamy. The song is traditionally very somber, so it's odd to hear such a positive version.
Match Cut: In a variant, Marty accelerates up to 90 mph in a drive-in movie theater. He speeds towards a mural depicting the background landscape with an Indian raid. He hits 88 mph, and from the perspective of the viewers, jumping back to 1885, the car is suddenly now racing towards a landscape of actual Indians being chased on horseback by a cavalry charge.
May-December Romance: If you're being very gentle with how old Doc must be, he still must be at least twice Clara's age. Of course, Doc paid a visit to a rejuvenation clinic in 2015 that added thirty to forty years onto his life, so it's not as unfortunate as it sounds. They also replaced his spleen and colon.
Mood Whiplash: One of the reasons why the scene where Buford shoots Marshal Strickland was removed. The producers thought it was too depressing, and after doing it, it didn't seem right that Buford not die. They were worried it would make audiences want Marty to kill Buford, and he can't, because Buford needs to live long enough to extend the Tannen family line. In 1985-A in Part II, Buford was explicitly identified as Biff's great-grandfather, meaning Marty couldn't risk killing him. This leaves a minor plot-hole in the scene when Buford is arrested by Marshal Strickland's deputy instead of by Strickland himself. However, even if the scene were kept, it's possible Biff would have been born regardless because Part II does show that he lives with his grandmother Gertrude in 1955, who is implied to possibly either be Buford's child or married to one of his.
At the end of the movie, right after Marty makes it back to 1985, we see a sign for "Eastwood Ravine," and it looks like the DeLorean has triggered the grade crossing gates at the end of the bridge — both funny moments. A few seconds later, a modern train destroys the DeLorean — one of the most iconic cars in cinematic history — and Marty realizes that this strands his best friend in the past.
The look on Doc's face when Buford comes to shoot him on Saturday, and he realizes that just because he died in the original timeline on Monday doesn't mean that's when he got shot. This is lampshaded by Buford by explaining that his derringer, despite its small size and ability to only shoot one shot, causes a slow, agonizing death.
Similarly, when Marty tells Doc that the fuel line on the DeLorean was ruptured. Doc tells him that the car always ran on gasoline to get it up to 88 miles per hour - the Mr. Fusion had nothing to do with that - and there ain't no refined gasoline in 1885.
Oireland: Seamus and Maggie McFly, complete with stereotypical (and non-existant in reality) accents.
Ominous Pipe Organ: Heard when Marty confirms to Doc that he returned to 1955 even after being sent to the future. In-universe: backed up against the organ in his house in terror at Marty's apparition, Doc's groping hands just happen to play a series of dissonant and ominous chords.
Prophecy Twist: The photograph of Doc's tombstone accurately predicts that he will die on Monday, September 7, 1885 by Buford shooting him in the back over a matter of $80 if history continues on the same course. Doc and Marty fail to realize that just because he dies on Monday does not mean he gets shot on Monday, hence Doc's surprise when Buford shows up to shoot him on Saturday is quite genuine .
Seamus McFly frequently is ridiculed for wearing a bowler hat instead of the typical Wild-west cowboy hat everyone else has on. The comedy in this may well have been intentional, but bowler hats were actually the popular style back then. The cowboy hat we know today (the Stetson)? Back then, it looked like this.◊
Yes, the word "dude" existed in the Old West. At the time it meant something like "city slicker", hence the existence of "dude ranches".
Schizo Tech: Invoked; by the end of the film, the DeLorean is a 1980s car, whose time circuits are powered by a 2015 fusion device, with jumps calculated by a computer built of 1955 vacuum tubes, running on 1885 train wheels.
There's also the time machine built out of a train which the Doc and family later arrive in, playing it somewhat more straight.
The Slow Path: The DeLorean does this — mothballed by Doc in an abandoned gold mine in 1885 so Marty can retrieve it 70 years later in 1955. Also, he has to leave a letter with Western Union to get to Marty.
Spear Carrier: The train engineer who asks if it's a robbery and Doc answers, "It's a science experiment."
Steam Punk: Doc's custom sniper rifle, the time train from the end, as well as Doc's refrigerator in the blacksmith shop. The sheer size and complexity of the refrigerator, along with the difficulty of getting a conventional steam locomotive up to eighty-eight miles per hour (easily done with an internal combustion engine), illustrate more "realistic" applications of Steam Punk tech. The time train at the end throws all realism out the window, but Doc once said, "If you put your mind to it, you can accomplish anything."
Unusually Uninteresting Sight: The Indians' reaction to the DeLorean when Marty arrives in 1885. True, they are being chased by the US Cavalry and one of the Indians hits the DeLorean with an arrow, but you would think at least a few of them would stop dead, especially since they just saw the DeLorean appear out of thin air in a flash of light.
Urine Trouble: The first McFly born in America greets his future descendant with this trope.
Voice Over Letter: Subverted. At the end of Part 2, Marty receives a letter from time-displaced Doc in 1885, and reads the first few sentences of it aloud. In Part 3, the entirety of the letter is read by Doc. What makes this case different is that it's read by 1955's Doc, who won't write the letter for another 30 years, and so is reading it for the first time along with the audience.
Only Child Syndrome: Both Marty and Lorraine have numerous siblings that aren't that important to the plot, and of course Doc and Clara have two children together. George and Jennifer are only children however. As far as we know, anyway — we never actually met George or Jennifer's family. In the novel, we meet George's family and it is implied he is an only child.
In Part I, Lou quips, "A colored mayor? That'll be the day" when Goldie Wilson muses after Marty tells Goldie that he will be mayor in 1985.
After locking Marty in the trunk, one of Biff's gang calls one of the Starlighters a "spook", which is a largely forgotten racial epithet for a black person. In kind, the band members respond by calling him "peckerwood", which was likewise a racial slur for a white person.
In Part 3, one of the old timers sees Marty in his hideous outfit and says "Must'a got that shirt off'n a dead Chinee..."
Retroactive Preparation: Apparently does not work. (If it did, after Marty got stuck in 1955, his future self would have popped in with some plutonium, easy-peasy, problem solved. Ditto 1885 and a gallon of gas.)
San Dimas Time: "If only I had more time... wait a minute, I have all the time I want; I got a time machine!" Marty then proceeds to screw it up by giving himself only a few extra minutes, thus allowing him to make it back to the mall parking lot just in time to see Doc get shot.Justified in that he hadn't counted on the starter for the DeLorean failing. Again.
Time Crash: Doc is concerned that causing an unresolvable time paradox or having someone encounter his or her past self could potentially destroy the timeline.
What Year Is This?: Marty looks at newspapers instead. And of course, the DeLorean has a bright digital display that tells you exactly when you are.
Although Doc's letter at the end of Part 2 sort of plays this trope straight (the only part of the Trilogy to do so), though Rule of Cool applies for obvious reasons.
The 1955 Doc averts this. He specifically sends Marty back to a point after 1985 Doc has left the letter with Western Union. As can be seen in Part III, they didn't do anything about it, which allowed for normal 70+ year delivery. ...and the Western Union guy lost the bet!
