Although it's been 22 years since the last film was in theaters, Wilson's still fielding queries about what it was like to work with Michael J. Fox ("Michael J. Fox is nice. I'm not in close contact with him"), hoverboard stories ("The hoverboards didn't really fly, we were hanging by wires from a cane") and what the maure was made of ("The manure was made from peat moss, cork, dirt and a food agent that made it sticky").
Oh, and what about Biff's famous catchphrases? "Among the many improvisations on set, I termed the coin 'butthead,' as well as 'Make like a tree, and get out of here.'"
