    In general 
  • Acting for Two:
    • Michael J. Fox plays Marty, his older self in 2015, his children Marty Jr. and Marlene (yes, the daughter), and Seamus in 1885. He also posed as William for the picture of him in Part III, who he also later voiced in the Telltale game.
    • Christopher Lloyd shares a scene in Part II with himself as Doc meets his 1955 self.
    • Thomas F. Wilson plays 1955 Biff Tannen, 1985 Biff (three versions, no less: the Jerkass from the beginning of Part I, the wimpy version from the end of parts I and III and beginning of Part II, and the Jerkass In Chief from the 1985-A universe in Part II), 2015 Biff and his grandson Griff, and Buford "Mad-Dog" Tannen in 1885.
    • Lea Thompson portrays both Lorraine Baines McFly, George's wife, in 1955, three versions of 1985, and 2015, and Maggie McFly, Seamus's wife.
    • Elisabeth Shue plays Jennifer's younger and older self at the same time in Part II.
  • Creator Backlash: Crispin Glover was infuriated with the sequels because the production used Stock Footage from the first film with an especially convincing lookalike as The Other Darrin to the point that many people do not realize he had no part in them, and so is credited for a performance that he didn't do. He successfully sued for misappropriation of his likeness. While he later patched up his relationship with Robert Zemeckis, he has nothing positive to say about writer/producer Bob Gale.
  • Dawson Casting: Marty, Lorraine, George, Biff, Jennifer, etc. Makes some sense in Lorraine, George, and Biff's cases, since in the first movie they had to play both their teenage selves and their adult selves. Initially, not so much the case with Jennifer, who was played by 19-year old Claudia Wells in the first film, but then played by 26-year old Elisabeth Shue in the Sequels and that wig she wore to make her resemble Lea Thompson made her look every bit her age.
  • Defictionalization:
    • There are no back seats in a DeLorean, original or newly built; they only have a pair of front bucket seats. (That's why Jennifer had to ride sitting in Marty's lap.)
    • Marty's entire 2015 outfit is available to purchase. Nike sneakers with self adjusting laces can be yours... for $1,700. You can even buy a Hoverboard, although obviously non-functional (a joke by Zemeckis during a "Making of" video implied the Hoverboards were real devices about to come on to the market, and so Mattel was bombarded with questions about them).
    • A Match Made in Space, George's novel, was kinda-sorta defictionalized. The book itself was made as a blank diary with the book's cover, and a companion book has the short summary that would go behind one of the covers on the dust sleeve.
  • Disowned Adaptation: Bob Gale hated many of the video game adaptations of the franchise, particularly the first one by LJN Toys. According to him, the makers of the game didn't want any input from the filmmakers, and when he saw it, he wanted a lot changed, but was told it was too late to do anything. He advised fans not to buy it, and felt that Telltale Games handled the process much better.
  • Executive Meddling:
    • Basically, this is the whole reason why the sequels exist in the first place — but Sid Sheinberg had insisted on certain changes to be made in the first movie.
    • One of Sid Sheinberg's changes, from "Professor Brown" to "Doc Brown", has become integral in Back to the Future culture. (Just how much so is suggested by Michael J. Fox's repeated bloopers in filming The Frighteners: he called the Judge character "Doc".) He also insisted on Emmett Brown's chimpanzee pet being changednote , which became the dog Einstein, and requested Marty's mother's name go from Meg to Lorraine (his wife's name). The last note is mentioned in the first film's trivia in regards to the title, to which the Bobs adamantly stuck to their guns.
    • Cost considerations forced a complete change in the tactic to return to 1985 in Part I, from powered by a nuclear test explosion to powered by the lightning bolt. By all accounts, it was a major improvement, as keeping it "local" in Hill Valley added an immediate urgency and gave Doc something to do with the clock tower (in the original script, he simply watched from a mountainside).
  • Fake American: Marty McFly — Michael J. Fox is in fact Canadian. You can hear his accent when he pronounces "sorry" as "sore-y."
  • Hey, It's That Place!: Courthouse Square, on the Universal Backlot, has been in dozens of productions. The set tragically burned to the ground in 2008. It has been rebuilt, however.
  • I Am Not Spock: Actor Thomas F. Wilson (Biff). He even wrote a song about it. He also started carrying small laminated cards he'd hand out to fans he'd run into, featuring answers to the most frequent questions he's asked about the movies. Not only is he exactly the opposite of a bully (and Biff) in real life, he drew on his real life high school experiences of BEING bullied in order to play Biff.
  • Older Than They Think: There actually is another movie called Back to the Future about time travel that predates the 1985 film by twelve years! Ivan Vasilevich menyaet professiyu, translated from Russian to English is Ivan Vasilievich: Back to the Future. It is about Ivan the Terrible being teleported from 16th century Moscow to 1973 USSR. Not only that but a car used in the film, a 1947 ZiS 110 B, is identical to a early-to-mid 1940s Packard, the same model of car that Doc drives in 1955.
    • Ivan Vasilevich menyaet professiyu actually literally translates to Ivan Vasilevich Changes Professions, so there's no connection between the two films (coincidental or not) other than time travel.
  • The Other Darrin: Jeffrey Weissman replaced Crispin Glover as George McFly in the sequels. Likewise, Elisabeth Shue replaced Claudia Wells as Jennifer Parker.
  • Playing Gertrude: Crispin Glover is three years younger than Michael J. Fox, Thomas F. Wilson is two years older than Fox, while Lea Thompson is only nine days older than Fox. As mentioned in Dawson Casting above, Glover, Wilson, and Thompson played both their characters' older selves and their teenage selves.
  • Pop Culture Urban Legends: Once real-life history got into the decade of the 2010s, pretty much every year there would be a picture claiming that that day was the day Marty went to when he went to the future (with the date being photoshopped to the current date). It's easy to tell the fakes, since the real years in the movies all end in 5. Now that the real date has passed, only time will tell if these fakes will stop being made.
  • The Red Stapler:
    • The DeLorean. At the time the movie came out the Delorean Motor Company had been bankrupt for almost 3 years and DeLoreans were considered a failed car. Nowadays there's an active "time machine conversion" community, DeLorean dealers, and DeLorean conventions — all because of Back to the Future. There's apparently even a company in Texas that bought the rights to the design and is making new DeLoreans.
    • The skateboarding sequences in this film resulted in a boom in the sport's popularity.
  • 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.
  • Star-Making Role: For Michael J. Fox.
  • Trope Namers: These movies named the following tropes:
  • What Could Have Been: In 2018 there were plans for a manga, illustrated by Yusuke Murata (of One-Punch Man fame) and overseen by Bob Gale, which would have followed on the events of the original movie. However, due to rights issues the project was cancelled, leaving us with nothing but a few pieces of leftover artwork.
  • The Wiki Rule: Futurepedia, the Back to the Future Wiki.

    Part I 
  • Banned in China: The film was banned in China mainland for a while because the notion of time travel "disrespects history". The ban has been lifted by now.
  • Cast the Runner-Up: J.J. Cohen was originally cast as Biff Tannen. However, he didn't look so imposing against Eric Stoltz, the Trope Namer for The Other Marty, so Thomas F. Wilson was cast as Biff while Cohen was recast as Skinhead, one of Biff's Mooks. According to Bob Gale, had Michael J. Fox been cast as Marty from the beginning, Cohen would definitely have landed the role of Biff/Griff/Buford Tannen instead of Wilson. Billy Zane also auditioned to play Biff before being cast as another one of Biff's mooks, Match.
  • The Cast Showoff: Kind of. Although Michael J. Fox is miming his performance of "Johnny B. Goode" he did actually learn to play the song (having played guitar in high school) so he could do so accurately. The guitar solo was actually played by Tim May, who also had previously performed the guitar solo on "Born to Hand Jive" from Grease.
  • Channel Hop: Zemeckis and Gale originally pitched the film to Disney and then to Columbia Pictures, both of whom turned it down, albeit for completely different reasons: Columbia felt it was too quaint (this was the era of sex comedies like Animal House, Porky's and Revenge of the Nerds), Disney thought it was too raunchy (in particular, they took umbrage with the angle of 1955 Lorraine coming onto her future son).
  • Creator Backlash:
    • Although Eric Stoltz was replaced by Michael J. Fox (a few clips of him remain in the finished film), Stoltz regretted his involvement in BTTF. At one point, Stoltz turned down an offer to be interviewed for a BTTF companion book.
    • Crispin Glover was intensely displeased over the ending, in which Marty and his family are more well off and Biff now works for George instead of the other way around, claiming it to be too materialistic and lacking enough heart, as well as sending a bad message that it's okay for one to bully back his former bully.
  • Deleted Scene:
    • Wonder why George had peanut brittle for dinner in 1985? Originally, after meeting with Biff, Marty tries to urge George to stand up for himself when a child selling peanut brittle shows up. Instead, he caves, buying all of it, with the child's father saying "See, I told you we'd only have to stop at one house."
    • After the "Mister Sandman" Sequence, Marty asks a woman to pinch him to see if he's dreaming.
    • The 1955 Doc looks at the contents of his 1985 counterpart's suitcase, which include a Playboy magazine and the hair dryer Marty takes with him while playing "Darth Vader".
    • In 1955, before Doc gets introduced to George, Doc and Marty see Lorraine cheating on a quiz in class, surprising Marty.
    • The Darth Vader scene was longer, ending with Marty knocking George out with chloroform, explaining how George overslept and missed school. It got cut because it lasted too long and was redundant.
    • While discussing their plan, Marty tries to get George to hit him as practice.
    • Just when Marty leaves for the dance, Doc gets asked for a permit by a cop for his "weather experiment", and Doc gets it: a $50 bill, quite a bit of money back then. Also, Marty worries about his plan, asking "What if I go back to the future and I end", to which Doc says "Why shouldn't you be happy?"
    • George, realizing he's late during the dance, goes into a phone booth to confirm the time, but Dixon, the bully who'd kicked George and later cuts in on him and Lorraine, traps him inside, with Strickland chastising him.
  • Enforced Method Acting:
    • Two examples that didn't make the film because of Eric Stoltz. When they filmed the cafeteria scene, Stoltz roughed up Thomas F. Wilson for real and Wilson almost broke his collarbone. The normally nice guy Wilson planned to get revenge during the car park scene at the dance by actually punching Stoltz but Michael J. Fox had taken over by then so he never got the chance.
    • An unintentional example, but remember that Michael J. Fox was filming the first movie at night while still keeping his obligations to Family Ties during the day. Any scene where Marty looks wiped out and exhausted from everything going on is most likely not acting.
  • Hostility on the Set:
    • Tom Wilson has said that he and Crispin Glover didn't get along very well with Eric Stoltz when he was initially playing Marty, as Stoltz acted fairly arrogant throughout filming. Wilson even said that for years he thought Stoltz was fired due to his behavior on set, not because the producers wanted Fox originally.
    • Post Stoltz firing, the cast became very timid towards the producers because they felt their job was in danger, after all they fired the lead actor months into filming. Lea Thompson was heartbroken because she was friends with Stoltz, having previously worked with him in The Wild Life, while Crispin Glover didn't come back for the sequels because of bad blood between him and producer Bob Gale (who claimed for years Glover was a prima donna asking for an absurd pay hike).
  • Inspiration for the Work: Bob Gale conceived Back to the Future after he visited his parents in St. Louis, Missouri. Searching their basement, Gale found his father's high school yearbook and discovered he was president of his graduating class. Gale had not known the president of his own graduating class, and wondered whether he would have been friends with his father if they went to high school together.
  • Irony as She Is Cast: As opposed to the initially Extreme Doormat role of George McFly, Crispin Glover was actually very demanding and very argumentative, and, in fact, always tended to be at loggerheads with Robert Zemeckis and Bob Gale over various matters.
  • Looping Lines: Crispin Glover lost his voice due to nervousness while filming. For some scenes, he had to silently mouth his lines, with his voice being dubbed in later at a recording studio.
  • Non-Singing Voice: Michael J. Fox did not sing "Johnny B. Goode" (the final singing audio was recorded by Mark Campbell), although he did learn to play it. For bonus points, his guitar coach Paul Hanson taught him to play the song in B, figuring an 80s guitarist like Marty wouldn't play a song in B flat. He's playing the song on-set in B and says it's a "blues riff in B," but nobody told Tim May, the guitarist who recorded the final audio, so the film audio is the original B flat version. Of course, May was more well versed in 50s music, having previously played the guitar solo on "Born to Hand Jive" from Grease.
  • Orphaned Reference: Ever wonder why George had peanut brittle for dinner in 1985? Originally, after meeting with Biff, Marty tries to urge George to stand up for himself when a child selling peanut brittle shows up. Instead, he caves, buying all of it, with the child's father saying "See, I told you we'd only have to stop at one house."
  • The Other Marty: The Trope Namer.
    • Eric Stoltz was cast as Marty, and filmed some scenes, before being replaced by Michael J. Fox because people felt Stoltz was too serious for the role - all of which was a tad bit ironic considering that Fox was always the first choice for the role and came on as the replacement for the actor meant to replace him. A few shots of Stoltz remain, namely of Marty driving the Delorean and Biff being punched. They finally did include some Stoltz footage in the Blu-Ray release of the trilogy.
    • J.J. Cohen was initially chosen to portray Biff Tannen before Thomas F. Wilson was cast. However, Cohen was replaced from the role as he wasn't considered physically imposing enough next to Stoltz and was cast as one of Biff's gang members instead. According to Bob Gale, had Michael J. Fox been cast from the beginning, Cohen would've probably won the part, because he was much taller than Fox.
    • When Claudia Wells temporarily dropped out of the movie due to scheduling issues, Melora Hardin was briefly cast as Jennifer Parker opposite Eric Stoltz, but had to be replaced after he was dismissed as it was discovered that she was taller than Michael J. Fox. Ironically enough, it was the female crew members who complained about the height disparity between Hardin and Fox, while the male crew members had no problem with it, whatsoever.
  • Prop Recycling: According to the documentary on the Blu-ray, the two cat sculptures standing beside the clock were originally created for Cat People.
  • Quote Source: Of Cool Car.
  • Sleeper Hit: No one expected the movie to become as big as it did. Robert Zemeckis openly admitted he was just hoping it would break even and the final bit with the Delorean flying and "something's got to be done about your kids!" was meant as a joke on Marty having just changed the past for his parents. Michael J. Fox recalled that when he was in London filming the Family Ties tv movie, his agent called and told him that the movie was a hit. He was pleased, but the agent had to reiterate that it was a BIG hit.
  • Technology Marches On: Lampshaded In-Universe:
    • First, when Marty dines with his future maternal family in 1955, Lorraine asks whether his family owns a television set, to which Marty says, "Yeah, you know we have two of 'em...", making her younger brother say "Wow, you must be rich!", to which their mother says, "Oh, honey, he's just teasing you. Nobody owns two television sets!"
    • Later, Marty tries to explain his knowledge of an episode of The Honeymooners as having seen it as a rerun. In several non-English dubs of the movie, the word 'rerun' doesn't exist (usually because the country concerned had not adopted the policy of re-airing episodes of television shows as of the mid-eighties), so Marty says instead that he saw "The Man from Space" episode of The Honeymooners "on tape".
    • As the 1955 Doc looks at Marty's camcorder, he says "Now this is truly amazing: A portable television studio. No wonder your president is an actor, he's got to look good on television!"
  • Throw It In!:
    • Many of George McFly's mannerisms (the shaking hands, the infamous Honeymooner's laugh) were ad-libbed by Crispin Glover. Glover explained years later in an interview that he saw the original 1985 George as a deeply unhappy man, and that his laugh at such a trivial moment on TV was his way of forcing out happiness. Allegedly, much of that was Glover's normal behavior, and the real challenge was getting him to act normal for the improved-1985 scenes.
    • Huey Lewis improvised the line "I'm afraid you're just too darn loud", as the silly excuse for Marty's band to be rejected.
    • During the "Mister Sandman" Sequence, when Marty sees the 1955 Texaco gas station, there was originally only one attendant working on a car, but Robert Zemeckis had the costume department find 3 more attendant costumes, believing it'd be funnier.
    • According to Bob Gale, Red (the homeless guy)'s name was ad-libbed by Michael J. Fox, so he isn't Red Thomas, the mayor of 1955 Hill Valley.
  • Troubled Production: Everyone involved in the film was sure it would bomb because absolutely nothing went smoothly. (Among the crew, it was nicknamed The Film That Would Not Wrap.) The shoot nearly drove Robert Zemeckis insane, ruined his health, and threatened to wreck his career if the film wasn't a hit.
    • The script for the film floated around Hollywood for years. Writer-Director Robert Zemeckis and his cowriter, Bob Gale, were shot down by several studios for various reasons; Disney and 20th Century Fox considered the script too raunchy while Columbia Pictures thought it was too quaint, and others were hesitant due to their involvement in the Box Office Bomb 1941. The film finally landed with Universal Studios after the two scored a hit with Romancing the Stone, but the film's script underwent heavy rewrites just prior to filming, some of which was due to budget limitations and Executive Meddling.
    • Zemeckis reportedly wanted Michael J. Fox from the start to play the lead role of Marty McFly, but Fox was busy with Family Ties, so they casted Eric Stoltz in the role. According to Thomas F. Wilson, neither he nor Crispin Glover got along with Stoltz and found him arrogant. The producers had their own complaints with Stoltz, finding him too much of a dramatic actor for a comedy film and annoyed by his insistence on Method Acting. Crispin Glover lost his voice due to nervousness while filming, and butted heads with Zemeckis and especially Gale (which led to him refusing to reprise his role in the sequels).
    • Six weeks into filming, a deal was reached to work Michael J. Fox into the film around the schedule of Family Ties. Stoltz was quickly fired and replaced with Fox, and Stoltz's scenes were reshot with Fox in the role. Stoltz was reportedly very upset when Zemeckis broke the news, and to this day he refuses to talk about the film. His firing made the rest of the cast very nervous about their job security, with Lea Thompson in particular being dismayed as she was good friends with Stoltz, having previously worked with him in The Wild Life. Despite this, overall mood on the set improved with Fox in the role.
    • And because of working two productions at once, Michael J. Fox was running on fumes, commuting between the BttF and Family Ties sets with virtually no sleep in-between. He would record the show during the day and film the movie at night, once he went into a panic on the show because he thought he needed the camcorder prop he was actually using for the movie. In his interview on Inside the Actor's Studio, he notes that he was basically a zombie, which luckily enhanced his acting a fair bit.
  • What Could Have Been:
    • Eric Stoltz was originally cast as Marty McFly before Michael J. Fox was hired. While Fox was always the first choice for the role, the production team behind Family Ties didn't want him absent from the series during Meredith Baxter's pregnancy. After six weeks of filming, Robert Zemeckis and Bob Gale decided that Stoltz was too much of a dramatic actor for a more comedic part. By this stage, Baxter was back fully on the series and the producers finally agreed to let Fox go off to star in the film.
      Gale: Geez, I don't even remember that we read Johnny Depp! So whatever he did, it wasn't all that memorable, I guess!
    • John Lithgow was the first choice for the part of Doc Brown before the casting of Christopher Lloyd. However, Lithgow turned down the offer due to scheduling commitments to Twilight Zone: The Movie.
    • Tim Robbins, Daniel Stern, and Vincent D'Onofrio were considered for the role of Biff Tannen before Thomas F. Wilson was cast.
    • The original time machine was a modified refrigerator, changed because it would have been a very stationary prop and Steven Spielberg had images of children locking themselves in the fridge to the horror of their parentsnote  (humorously, he would later use a refrigerator and a nuclear explosion in Indiana Jones and the Kingdom of the Crystal Skull). They also would have driven into the blast of a nuclear bomb to fuel the flux capacitor, changed because that alone would have doubled the production costs and the clock tower lightning strike made a fairly simple and stationary location.
    • Jon Cryer and Ben Stiller auditioned for the role of Marty in a very different version. In this draft, a more generic time machine and the aforementioned fridge. However, the time machine required a special ingredient to work: Coca-Cola. In the finale, Marty sneaks into a nuclear testing site, complete with detailed suburban houses. As the countdown starts, he drops the bottle of Coke, and it shatters on the floor. He panics at first, until he realizes that like any American home in that era, the fridge is stocked with another bottle of Coke. It's also lead-lined, so hiding in there lets him survive the blast. This conveniently gives Marty everything he needs to go back to the future. Also, Marty played the Close Encounters of the Third Kind theme on his guitar while pirating a VHS copy of it in the opening scene.
    • One version of the script had Biff as a cop that kept "borrowing" stuff from George and had a daughter. After Marty changed the past, Biff became a security guard working for George, who became a boxing champion.
    • The producers considered using "Papa Loves Mambo" by Perry Como when Marty arrives in the 1955 Hill Valley, before deciding on "Mister Sandman", thereby making it the "Mister Sandman" Sequence. "Papa Loves Mambo" would however show up in Part II where it's the song playing on the car radio as Biff drives to the dance..
    • There was originally going to be an explanation as to why Marty and Doc were friends: Doc just showed up one day and hired Marty to clean his garage, paying him $50 a week and free beer.
    • Originally when Marty looked Doc up in the past, Doc was going to be having a party, and was flanked by two women when he opened the door. The scene played out the same, but with Doc's two girlfriends laughing at Marty. Then, instead of getting the idea for time travel from falling down while hanging a clock, Doc was inspired after whispering something into a woman's ear and subsequently being hit in the head with a beer bottle.
    • In the original treatment, the time machine was rigged up inside a car wash. Marty McFly was chronically depressed, and in a hilarious misunderstanding, he mistook the time machine for a suicide device and climbed into it in order to kill himself. Also, there was originally going to be a major plot point where people in the past repeatedly mistook Marty for an alien.
    • The studio wanted Zemeckis to cut the "Johnny B. Goode" scene to improve pacing, but relented because the test audiences considered it one of the best parts of the movie.
    • Doc was originally called "Professor".
    • As indicated in the novelization, there were once as many as six Libyan terrorists, including a Dark Action Girl named Uranda. The leader was named Sam, who started out as a Child Soldier (he's in his early forties in 1985 and mentioned to have been a terrorist for 30 years).
    • In the scenes shot with Eric Stoltz, Marty was dressed in a black jacket and pants with a white t-shirt, with the idea being that it'd be something a teen in 1985 might wear that, while appearing contemporary, conveniently wouldn't stand out much in 1955. Once Michael J. Fox took over the role, it was decided it would add to the Fish out of Temporal Water comedy if his clothing didn't fit in for 1955, leading to Marty getting a more distinctly 1980s look.
  • Working Title: The film was almost titled Spaceman from Pluto due to Executive Meddling. It took the intervention of Steven Spielberg to get this resolved.

    The Animated Series 
  • Channel Hop: More than a decade after the original run on CBS, the show resurfaced from March to August 2003 on Fox on their then-new "Fox Box" Saturday morning lineup, programmed by 4Kids Entertainment- likely to fill the E/I quota.
  • Creator Backlash: In one interview, Bill Nye talks about a science demonstration segment he did where he was meant to demonstrate static electricity with two balloons sticking together. While they were filming, there wasn't enough static built up on the balloons to get them to stick, so the crew used some 77 adhesive spray to get them to stick, which in Nye's opinion completely ruined the realism of the demonstration.
  • Keep Circulating the Tapes: Only 18 episodes made it to VHS and Laserdisc, and none of them made it to DVD until October 20, 2015, when Universal released a Complete Series DVD set of the show—one day shy of the "futuristic" date Marty, Doc, and Jennifer visited in BTTF Part II. Up until then, you had the aforementioned incomplete releases, and whatever tapes were circulating from the original run on CBS, and the reruns on Fox (see above).
  • The Other Darrin:
    • In the animated segments, only Mary Steenburgen (Clara) and Thomas F. Wilson (Biff) reprised their roles from the movies.
    • In a bizarre version of this trope, Christopher Lloyd played Doc in the live-action bits, and Dan Castellaneta played his animated counterpart.
    • In the French dub, only Luq Hamet (Marty) reprised his role from the films.
  • What Could Have Been: The head of children's programming for CBS suggested adding an alien to the ensemble for season two, but Bob Gale nixed the idea.

    The Pinball Table 
  • The Other Darrin:
    • Michael J. Fox did not allow his likeness for the game. Instead, artist Paul Faris' son plays Marty on the playfield and the backglass.
    • Similarly, it's unclear who voiced "Marty", but everyone agrees the voice doesn't even come close to sounding like Michael J. Fox.
  • Real Song Theme Tune: In addition to the movies' main theme, the game features ZZ Top's "Doubleback" and Huey Lewis and the News' "The Power of Love" and "Back in Time".

    The IDW comic book 
  • Ascended Fanon:
    • George's reluctance at letting Robert Zemeckis adapt A Match Made in Space into a movie references an article in USA Today's Real Life reproduction of the 2015 newspaper cover prop. According to this page, the phony article was written by Gannett vice president Matt Urbanos to replace the junk filler used by the original newspaper prop.
    • One popular fan theory was that Doc reverse engineered the hoverboard in order to get the time train working, since the board was pretty much the only bit of future tech at his disposal at the time. This idea was sort of used in "Continuum Conundrum," when Doc mentions he used components from the hoverboard to help get the steam trike time machine working.
    • It confirms Cracked's theory that Doc burned his house down for insurance money.
  • Development Gag:
    • Doc Brown's prototype flux capacitor is called a "temporal field capacitor," which was the original name of the flux capacitor in early script drafts of the first movie.
    • Biff's daughter Tiff, who was considered as a character for the Telltale game but was ultimately dropped, shows up in the "Tannenville" timeline in the "Citizen Brown" adaptation of the game's story.
    • Supplemental materials for Back to the Future: The Ride, once kept on Universal Studios' website, included Doc's plans for a "Timeman" time machine suit that is activated when the wearer runs to a speed of 8.8 mph. In the comic, Doc manages to create a time machine suit using a Victorian-era diving suit from 1893, although he still has to reach 88 mph for temporal displacement.


How well does it match the trope?
