FILM 1389: BACK TO THE FUTURE PART II

Crispin Glover sued the filmmakers, as he had not granted permission to use his likeness in Part II. Crispin's suit named John Doe 1-100 as defendants, where he did not have to name all of the individuals he was suing. Crispin ended up dropping the lawsuit after the case was settled out of court for $765,000 by Universal's insurance company, who decided it would be cheaper to pay Crispin than to actually go to trial. The Screen Actors Guild subsequently introduced new rules about illicit use of actors.

First film appearance by Elijah Wood. He plays one of the two video game boys that Marty speaks to in the diner near the start of the film.

Renowned scientist Carl Sagan considered this the greatest time travel movie ever made. He praised the accuracy in handling the multiple time lines as what would really happen if time travel were possible. In Back to the Future: The Game, Carl Sagan is the alias used by Doc Brown when visiting Hill Valley in 1931.

The biggest effect of the picture is the vista glide. There are three scenes that use the effect of the same actor interacting with themselves. The three scenes that were shot was the dinner sequence in 2015, 1955 Biff talking to 2015 Biff in the garage and 1955 Doc talking with 1985 Doc. In order to create the dinner sequence with the vista glide, the camera had to be divided into thirds and Michael had to come in three different times to play his older self, Marty Jr. and his daughter Marlene. Back to the Future Part II (1989) is the first film to accomplish interaction between the same actor on the screen twice as two different characters. If you watch closely, you'll see that old Biff's hand disappears during the scene in the garage.

During filming of the cut sequence where the McFly family gathers around the table in 2015, between takes they had an earthquake, and were afraid the props may have moved around too much to edit the scene seamlessly as Michael J. Fox had played 3 characters in the same shot. To the film crew's surprise however, everything was exactly where it was supposed to be for the sequence.

When "Hill Valley" was created for the original Back to the Future (1985) they built the town in the pristine 1955 condition and shot the middle of the movie, then damaged it for the 1985 town and shot the beginning and end of the movie. When they decided to shoot Back to the Future Part II (1989) they had to clean the set up and restore it to the same condition it was in 1955. It cost more to rebuild than it cost to build it from scratch.

The soda menu at Cafe 80's listed four types of Pepsi products: Original, Diet, Max, and Perfect. Pepsi Max did became an actual flavor by 1993 in Europe. The American version was introduced in 2007.

Doc mentions to Marty that he visited a rejuvenation clinic in the future to make him appear younger. This was written so that Christopher Lloyd would not have to constantly wear old-age makeup for the two sequels, since he would primarily be portraying the 1985 incarnation of Doc.

On September 8, 2011 the Parkinson's Research Foundation announced that 1,500 pairs of the futuristic Nike MAG shoes based on the sneakers worn by Michael J. Fox in this movie would be auctioned off on eBay. The first pair sold to rapper Tinie Tempah for the winning bid of $37,500.

The film takes place on October 26, 1985, October 21, 2015, from October 26 to October 27, 1985 in the alternate timeline and on November 12, 1955.

The original theatrical and premium cable TV versions of the film end with the phrase "To Be Concluded" and a teaser for Back to the Future Part III (1990). Russ Meyer and Richard Lester are the only other filmmakers to have ended a movie with a trailer before this release. (Recent 2009 premium cable TV versions have dropped the teaser.)
