    According to the website of the Ronald Reagan Presidential Library, President Ronald Reagan watched the film for the first time at Camp David on Friday, July 26, 1985 (three weeks after its release). Watching the film alongside the president was his wife, Nancy, and several aides including speechwriter Mark Weinberg. Although Reagan's fondness for the film is well-documented, Weinberg later recalled that the mention of Jane Wyman's name during one of the scenes made for a very awkward and uncomfortable moment in the room for the president and first lady. Apparently the subject of the president's first wife (from whom he had divorced in 1949) was such a sensitive one that White House staff members abided by an unofficial ban on ever speaking her name within earshot of any member of the First Family, according to Weinberg.

    In a 2015 interview with David Levin on his program "Pop Goes The Culture," Lea Thompson listed some of the reasons that the original actor cast as Marty, Eric Stolz, was deemed unsuited to the tole and was fired: "I had done this other movie with Eric Stoltz and so he just was really.... he had a really interesting process.... he liked to create friction [on a set], I think. He liked to be called by his character name all the time. He wouldn't answer if [you] said 'Eric,' he wouldn't answer, you had to call him by his character name, which a lot of people find hard, you know, to do. And he wanted to grow his fingernails really long because guitar players have long fingernails, and they were dirty and things like that that just weren't going over in a big giant summer teen movie. You know, they wanted him to be a teen idol. And they also, you know, dyed his hair and tried to cover up--he's got red hair--and they tried to cover up his freckles.... After the first read-through of Back to the Future everybody's sitting around [laughing and] going 'isn't that great,' you know, because it really was a great script, and they said 'Eric, what do you think?' and Eric said, 'I think it's a tragedy, really.' Silence. Tumbleweeds. And they said, 'why do you think it's a tragedy?' and he said--and rightly so--he said, 'my entire family remembers a past and I (Marty) remember a completely different past. It's a very sad thought to think that you would remember something, all kinds of memories, that no one else remembered.' He was right, but that wasn't the time to bring that up! He should have done that over cocktails with just me and a few close friends."

    There is a scene not featured in the movie that appears in the novelization which explains why George McFly grew up with no self esteem and never amounted to much. In the novel, George's father Arthur constantly discouraged George from taking chances or doing anything to better himself. As a result, George develops an intense fear of failure and abandons his plans to go to college and pursue his love of science fiction writing. But, in the novel, after knocking out Biff, George with his new found confidence tells Marty that he isn't going to listen to his father and is going to send in his college applications and work on his writing.

    Lea Thompson and Tom Wilson both recall how they learned Eric Stoltz had been fired. Wilson was called to a sudden in-person meeting with Zemeckis and Gale, where he almost broke down crying when told they had "bad news," assuming he was the one being let go. Instead, they told him, "We've had to let Eric go"—a name Wilson didn't even recognize at first because Stoltz insisted on going by his character's name, Marty. After Zemeckis assured Wilson he would still be paid for contract extension needed to reshoot the scenes, Wilson readily agreed. Thompson was harder to reach. Out of town on Friday, she had flown to Europe for a long weekend to visit her then-boyfriend Dennis Quaid on the set of Enemy Mine (1985). Producers had to make a series of frantic calls to her agent before finally reaching Thompson directly, urging her to return so they could break the news that her scenes with Stoltz had to be redone as well.

    The time machine has been through several variations. In the first draft of the screenplay the time machine was a laser device that was housed in a room. At the end of the first draft the device was attached to a refrigerator and taken to an atomic bomb test. Robert Zemeckis said in an interview that the idea was scrapped because he and Steven Spielberg did not want children to start climbing into refrigerators and getting trapped inside. (See also Indiana Jones and the Kingdom of the Crystal Skull (2008).) It was also changed into the more practical DeLorean because it looked more like a spaceship for the "Space Man from Pluto" gag. The Nevada desert bomb test was dropped in order to reduce the budget. In the third draft of the film the time machine was a DeLorean, but in order to send Marty back to the future the vehicle had to drive the DeLorean into an atomic bomb test.

    In the original script, Marty's playing rock and roll at the dance caused a riot, which had to be broken up by police. This, combined with Marty accidentally tipping Doc off to the "secret ingredient" that made the time machine work (Coca-Cola) caused history to change. When Marty got back to the 1980s, he found that it was now the 1950s conception of that decade, with air-cars and what-not (all invented by Doc Brown, and running on Coca-Cola). Marty also discovers that rock and roll was never invented, and he dedicates himself to starting the delayed cultural revolution. Meanwhile, his dad digs out the newspaper from the day after the dance, and sees his son in the picture of the riot.

    Walt Disney Studios has since acknowledged passing on distributing Back to the Future (1985) was a huge mistake as the movie remains one of the most popular films of all time. At the time Bob Gale and Robert Zemeckis pitched the idea in the early 1980's Disney hadn't dabbled much in more mature films and felt the subplot of Lorraine hitting on Marty was too risqué for their film banner while other studios including Columbia Pictures felt the film wasn't raunchy enough for the teenage audience Back to the Future was hoping to attract. By the time Disney did get involved with more mature material having launched their mature-oriented Touchstone Films brand in order to distribute Splash (1984) for Ron Howard they went back and asked Zemeckis if he would make the movie for the Touchstone Pictures label. However following the unexpected success of Zemeckis' Romancing the Stone (1984) from 20th Century Fox, Gale and Zemeckis had a distribution deal with Universal via Steven Spielberg to distribute Back to the Future. As a result and as an apology to Zemeckis Disney asked if he would be willing to make his next movie for them for passing on this one. Zemeckis agreed and made Who Framed Roger Rabbit (1988) for Touchstone which also proved to be a huge critical and financial hit and saw Zemeckis reuniting with Kathleen Turner whom he directed in Romancing the Stone and Christopher Lloyd whom he directed in this movie and its sequels.

    The original climax, involving a nuclear bomb test, was actually still in the script until partway through filming. It was actually the cost of modifying three DeLorean cars for use in the film that cause the change.

Rather than change their design for the car, Zemeckis and Gale decided to save money elsewhere.

Robert Zemeckis and Bob Gale then cast Eric Stoltz as Marty based on his performance in Mask (1985). After four weeks of filming which added up to roughly 40 minutes of footage with Stoltz, Zemeckis, Gale, and Steven Spielberg felt that Stoltz wasn't right for the part, and Stoltz agreed and was still paid his full salary. According to various cast and crew members, Stoltz was taking the role way too seriously, playing it as if he was in a drama, and insisting everyone call him Marty on set even when the cameras weren't rolling. According to Tom Wilson who played Biff, most of the crew cheered when Stoltz was fired because they were so fed up with his behavior. By this stage, Baxter was back fully on Family Ties and Goldberg agreed to let Fox go off to make the film. Fox worked out a schedule to fulfill his commitment to both projects. Every day during production, he drove straight to the movie set after taping of the show was finished, and averaged about five hours of sleep. The bulk of the production was filmed from 6 p.m. to 6 a.m., with the daylight scenes filmed on weekends. Reshooting Stoltz's scenes added $3 million to the budget. After Fox arrived on set, Zemeckis said that not only did Fox fit the character and movie better but everyone else's performances around him improved as well.

    Another of the numerous notes sent to Robert Zemeckis and Bob Gale from Universal studio head Sid Sheinberg were to change Doc Brown's original sidekick from a chimpanzee to a dog (Sheinberg argued that no film with a monkey in it ever made money, disregarding the recent Clint Eastwood hits Every Which Way But Loose (1978) and Any Which Way You Can (1980)). Sheinberg retorted that the simian in those films was an orangutan, not a chimp.

    When Robert Zemeckis was trying to sell the idea of this film, one of the companies he approached was Disney, who turned it down because they thought that the premise of a mother falling in love with her son (albeit by a twist of time travel) was too risqué for a film under their banner. In fact, Disney was the only company to consider the film too risqué. All other companies said that the film was not risqué enough, compared to other teen comedies at the time (for example, Fast Times at Ridgemont High (1982), Revenge of the Nerds (1984), et cetera).

    The speedometer shown is not an original DeLorean speedometer. It has a top speed of ninety-five miles per hour. This allows the movie DeLorean to reach eighty-eight miles per hour, as judged by that speedometer, although that speedometer shown does not exist on a real DeLorean. The original DeLorean vehicle can reach eighty-eight miles per hour, but the speedometer tops out at eighty-five miles per hour, and the needle would be pegged at the limit of the speedometer giving no ability to judge the speed. This is because of a 1979 traffic safety law that insured all speedometers in cars released after September of that year to top out at eighty-five miles per hour, in an effort to encourage drivers to travel at "safer" speeds. The law was overturned less than two years later, but by that time, DeLorean had gone out of business. There is the possibility, however, that Doc modified the instrument panel of the DeLorean for this very reason.

Fox, Hansen insists there was huge shift in mood during the screening of the dailies: "Now there was laughter in the room.

Shortly after shooting this scene, Stoltz got fired (for not being funny enough in his performance). Ironically, this was one of a few scenes where footage originally shot with Stoltz made it into the theatrical print: you can see Stoltz' hand striking Biff in the scene, not Michael J. Fox's.

    The time machine went through several variations. In the first draft, it was a laser device in a room; it eventually ended up mounted on a refrigerator and taken to an atomic bomb test. Robert Zemeckis said this idea was shelved because they didn't want kids getting into refrigerators and getting stuck. It was changed to the more practical DeLorean because it looked more like a spaceship for the 'Spaceman from Pluto' joke. The bomb test in the Nevada desert was cut to reduce the budget. In the third draft, the time machine was a DeLorean, but sending Marty to the future required driving the vehicle into an atomic bomb test.

    The original climax involving a nuclear bomb test remained in the script until the middle of shooting.

    A facet of Stoltz's somber performance (as Marty McFly) that most agitated producers was his interpretation of the non-incestuous dynamic between Lorraine and Marty. The filmmakers were only too aware how this character-development needed to be portrayed: Unambiguous Farce. Unfortunately, according to Lea Thompson, Stoltz's lead during their "Calvin Klein" scene (in Lorraine's bedroom), projected: "Nervous-despair."

    Life imitating art: Tom Wilson (Biff) did not get along with the first Marty McFly, Eric Stoltz, on set. In behind-the-scenes interviews, Wilson said that Stoltz made him uncomfortable, especially during the diner scene, at the moment Marty grabs Biff by the collar. Wilson stated that Stoltz was doing so much method acting that he nearly broke his collarbone while shooting the scene, at which point Wilson shouted and told him to back off. Shortly after this scene was filmed, Stoltz was fired (because his performance was not funny enough). Ironically, this scene was one of the few shot with Stoltz that remained in the film: the hand that punches Biff in the scene is not Michael J. Fox's but Stoltz's. A few more of Stoltz's shots remained in the final cut, usually in places where he cannot be recognized, such as the quick cut where Marty jumps into the DeLorean to escape the Libyans.

In this pivotal game, the Kansas City Royals took advantage of umpire Don Denkinger's blown call, rallying from certain defeat in the 9th inning to defeat the St. Louis Cardinals and tie the series (they won Game 7 the next day). Game 6 ended hours before Doc and Marty met up at the mall, so it's presumable that Doc would have seen or heard about what happened.

In turn, the feature film Mr. Peabody & Sherman (2014), based on the "Peabody's Improbable History" segment, pays tribute to this movie with not only its overall style, but a clever reference in a scene where Peabody and Sherman travel at unbelievably high speeds in the W.A.B.A.C., travelling at eighty-eight miles per hour (and higher), much like the DeLorean.

    In April 2020, Back to the Future screenwriter Bob Gale finally decided to explain the plot-hole question about why Marty's parents didn't remember him as the kid in high school who got them together. He told The Hollywood Reporter, "Bear in mind that George and Lorraine only knew Marty/Calvin for eight days when they were 17, and they did not even see him every one of those eight days. So, many years later, they still might remember that interesting kid who got them together on their first date." He continued, "But I would ask anyone to think back on their own high school days and ask themselves how well they remember a kid who might have been at their school for even a semester. Or someone you went out with just one time. If you had no photo reference, after 25 years, you'd probably have just a hazy recollection. So Lorraine and George might think it funny that they once actually met someone named Calvin Klein, and even if they thought their son at age 16 or 17 had some resemblance to him, it wouldn't be a big deal. I'd bet most of us could look thru our high school yearbooks and find photos of our teen-aged classmates that bear some resemblance to our children."

    During the Enchantment Under the Sea Dance, George can be seen drinking from a bowl of punch before he dances to the music and then comes to Lorraine's rescue. In the 1955 portion of Back to the Future Part II (1989), we follow the same events from young Biff's perspective for a while, showing how Biff pours alcohol into that same bowl of punch before George drinks from it. This means that George has unknowingly been drinking alcohol, and most likely got slightly intoxicated. This would actually be a reasonable explanation as to why the normally very meek George would feel comfortable enough to dance around on his own (to the point that he loses track of time and almost forgets to come to Lorraine's rescue), and how he showed such uncharacteristic courage in confronting Biff, even landing a punch on him despite being held in an arm lock. It also means that Biff is ironically responsible for his own downfall at the hands of George. Writer/producer Bob Gale has denied that he intended for George to be drunk in the original film, so this idea was likely conceived during the making of the second movie.

As a result, George develops an intense fear of failure and gives up his plans to go to college and pursue his love of science fiction writing. In the novel, however, after knocking out Biff, George tells Marty with his newfound confidence that he will not listen to his father and will send in his college applications and work on his writing.
