10 Awesome Deleted Scenes That Should've Been Restored
4. Old Biff Disappears Out Of Existence - BTTF2
The Scene: After time traveling to 1955 and giving his younger self the sports almanac and then returning to 2015, old Biff (Thomas F. Wilson) fades out of existence due to his past being altered.
Why It Was Deleted: Who knows? Perhaps it was considered too horrifying.
Why It Should've Stayed In: For one, it's extremely disturbing and shows how badly Marty (Michael J. Fox) could've suffered in the first movie, plus it also explains why old Biff seems in so much pain after returning to 2015. Instead, we're left to assume he's having a heart attack, was injured by his cane, or has been worn down by the effects of time travel on the human body.
