Back to the Future (1985)

Trivia: The script was rejected forty four times before it was finally accepted.

Trivia: While the young Doc and Marty get to the school there is a sign on the wall with "Ron Woodward" on it, that's a reference to Ronald Woodward, the key grip of the film.

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.

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.

Trivia: While Marty is holding the jeep and being pulled on his skateboard, there is sign for used cars, that's a reference to another Robert Zemeckis / Bob Gale film called "Used Cars" - Deborah Harmon had a part in that film and plays the newsreader in this one.
