Back to The Future Part 3 1990

Where Do They Start? Specifically, in this film, 1955. However, Marty McFly (Michael J. Fox) has done a lot of time travelling by this point.Where Do They End Up? 1885, where Doc Brown (Christopher Lloyd) is stuck.Biggest Culture Clash. Marty adopts the non de plume of Clint Eastwood to get by.Unresolved Paradox. If Doc Brown got stuck in 1885, and left his DeLorean for Marty to travel back to rescue him, that means there must be two DeLoreans in the Wild West now.
