The screenwriter of "Back to the Future" shared a draft of the second part. Everything is completely different there! The Stunt List first released the first version of the Back to the Future 2 script. It was written by Bob Gale, who worked on all the films in the trilogy. If you remember, in the final version, Marty goes back to 1955 to take the Sports Almanac from Biff and stop him from becoming the billionaire villain Donald Trump. It turns out that initially the hero arrived not in 1955, but in 1967. The police try to arrest him, and decide that he is evading the draft (the US is now waging a war in Vietnam). Marty's parents, George and Lorraine, are now hippie and go to anti-war demonstrations. The time traveler himself is also drawn to the anti-war movement, where he begins to play a prominent role. As the fiction world writes, the plot of the sequel was initially very similar to the first film: Marty again had to save his parents' relationship, and Doc Brown - in 1967, he rides a motorcycle and experiments with LSD - again has to find a way to get energy for the DeLorean. I haven't seen Back to the Future in a long time, but as I recall, the great thing about the sequel is that it takes place behind the scenes of the original: in the 1955 scenes we see two Martis and two Dukes at the same time. So it's not for nothing that Bob Gale and director Robert Zemeckis changed their minds about the sixties.
