The Hollywood Reporter says that Christopher Lloyd stated in an interview on Wednesday that he would be totally up for doing Back to the Future: Part IV if Robert Zemeckis, Bob Gale, Michael J.

He also states that he would like to toss out the first pitch if the Chicago Cubs get to the World Series, as predicted in ‘Back to the Future: Part II. That would be awesome!
