LOS ANGELES, Oct. 15 (UPI) -- Christopher Lloyd recently expressed interest in Back to the Future: Part IV.
The 76-year-old actor discussed a possible sequel in an interview with The Hollywood Reporter published Wednesday. Lloyd played Emmett "Doc" Brown in the first three movies, and told the magazine he'd reprise the role in a heartbeat.
"I would love to do Doc again, no question," he said. "It would be a real challenge for the writers to come up with an original Back to the Future story that has the same passion and intensity and excitement as the other three. But it could be done, you never know."
The first Back to the Future opened in 1985, with Lloyd as Doc and Michael J. Fox as Marty McFly. The actor said he'd immediately sign on for a new installment if Fox, Lea Thompson, Thomas F. Wilson, writer Bob Gale and director Robert Zemeckis got on board.
"I think regardless of the Parkinson's, [Fox would] probably jump on the role and he'd be great," he said. "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."
Lloyd and Fox recently reunited for a Toyota advert that sees them discuss "the future becoming reality." The full short film will be released Oct. 21, 2015 -- the date Marty travels to in Back to the Future: Part II -- which is being celebrated as Back to the Future Day.
Lloyd recently played Professor Hargraves on BYUtv series Granite Flats, and will next appear in Cold Moon with Robbie Kay. The actor is also scheduled for The Boat Builder with David Lascher, Lower Bay with Rose McGowan, and I Am Not a Serial Killer with Laura Fraser.
