10 Insane Things In Massive Movies (That Everyone Just Ignores)

10. Back To The Future - Biff Still Hangs Around

A classic light hearted film for all ages, Back To The Future suddenly turns much darker in the third act. The normally comical villain Biff Tannen comes across Marty's mother in her prom dress and quickly decides to force himself on her. Not a misunderstanding of her signals, but a very direct criminal assault. This is resolved when his father George arrives to defeat Biff and save the day.

We return to 1985 to find out that Marty's intervention changed his family for the better. His timid and unsuccessful father is now an author, his aged overweight mother is youthful and happy and his loser siblings are now successful. Many assumed we would see Biff in jail for his crime, or at least referenced as such, and were shocked to see him hanging around the house as though nothing had happened.

It's been thirty years for the adults so maybe they've forgiven, but Marty just accepts it and goes to admire his new truck as though he hasn't seen this man assault his mother barely ten minutes ago.
