During a sit down with The Hollywood Reporter, Christopher Lloyd revealed he would be interested in playing Doc Brown in Back to the Future 4 if the rest of the crew was in.
Would he return?: “I would love to do Doc again, no question.”
Would Michael J. Fox return?: “I think regardless of the Parkinson’s, he’d probably jump on the role and he’d be great I can’t see doing another sequel without him. I would certainly want Bob Zemeckis directing it, Bob Gale writing it and the other principals being involved.”
