Back to the Future Part II

Corrected entry: We all know that Old Biff stole the time-machine, went back to 1955 and gave the book to himself. He also returned the time-machine to Marty and Doc. WHY? He actually gave them the ability to restore the past. Why didn't Old Biff just keep the time-machine?

Correction: Biff doesn't know how time travel works. Presumably, he assumed that if he were to go back to the future, he'd end up in the alternate future he had just created (which would make sense) and become the 'rich' Biff.

Correction: Character choices are not mistakes.

Corrected entry: At the end of BTTF, Doc, Marty and Jennifer take off for the future. In BTTF2, they arrive 30 years later and see themselves. Impossible! They would have been inside the time machine (as far as those left behind are concerned) for 30 years. Marty and Jennifer were gone from 1985 to 2015 as far as he and everyone else knows. I can prove this by using the first movie. When Einstein goes into the future one minute, he was gone for a minute as far as Doc and Marty were concerned, even though the trip was instantaneous to Einstein.

Correction: Wrong - the reason Einstein is completely gone for that minute is because he never goes back to the time he left. While Marty, etc. go 30 years into the future, they will eventually go back to 1985 and live the rest of their lives, therefore he can exist in the future.

The whole point and premise of BTTF is that Time is very surely linear, such that altering the past changes the future in such a way that time travellers can even erase themselves from existence. The BTTF story is not about alternate timelines, it's about the pitfalls of travelling in linear Time.

Continuity mistake: Notice Marty's hair in the scene when he's playing "Johnny B. Goode." It's quite larger than when he says, some seconds later, "I guess that you're not ready for it yet." That's because when he says that, it's a recycled shot from the original BTTF, whereas most shots showing he's playing the guitar are newly made for BTTF2. However, Marty's hair is considerably longer in the new shots.

Trivia: In an interview, the director stated that hoverboards were real, but they weren't on the market because parents didn't like the idea of floating children. He said this as a joke, but this didn't stop mass hysteria as thousands of kids went from store to store looking for hoverboards.
