Trivia: To compensate for their height difference, Christopher Lloyd (6ft 1) would hunch over in close ups with Michael J Fox (5ft 4) so that they both appeared in frame. Robert Zemekis used blocking to position the actors far apart at different distances from the camera in wider shots.
Trivia: Despite what the ending shows, the movie's producers originally had no intention of creating a sequel. As director Robert Zemeckis reveals in an interview on the DVD releases, the whole finale was intended as a joke. After the immense popularity of the movie, however, Zemeckis and producer Bob Gale realised that they had to create a sequel and connect it to the "joke" ending of the first one. Once a sequel was in the works, "To Be Continued" was then added to the home video release of the first film.
Trivia: Christopher Lloyd (Doc Brown) and Lea Thompson (Lorraine McFly) have appeared in five movies together. This is the only film however in which they share on screen dialog.
Trivia: The town hall building is also seen in the Voyagers TV show.
Suggested correction: The Town Hall building is in over 100 movies and TV shows since it is a building in Courthouse Square at Universal Studios. It has also appeared in Gremlins, The Twilight Zone, To Kill a Mockingbird, Knight Rider, Leave It To Beaver, Parenthood, Saving Mr. Banks, and Psycho II, to name some of a few of the more commonly known. I don't think its common appearance makes this trivia relevant.
I'd say it makes it more relevant. Just add the multiple appearances of the building.
Trivia: Even though Lea Thompson and Crispin Glover play Michael J. Fox's parents in the movie, Thompson was the same age as Fox, whereas Glover was three years his junior.
Trivia: When Marty punches Biff in the diner, if you pause/use slow-mo you can tell it's not Michael J Fox that hits him, but it is actually Eric Stoltz, the original Marty, because he's taller and has more hair than Michael J Fox.
Trivia: 'Emmett' Brown's name is 'time' spelled backwards and pronounced as two syllables, 'em-it'.
Trivia: The script was rejected no less than 44 times before finally being accepted.
