2. Christopher Lloyd: Then
Fans of Lloyd remember him first from his role as Jim on the series “Taxi,” but Lloyd had been a busy actor his whole life. He initially tossed the BTTF script in the garbage. “… When the Back to the Future script came to me, Lloyd told the Sydney Morning Herald in 2017, “I had pretty much made up my mind I was going back to New York [to act on stage] and I cast it aside. A friend I was with at the time said that’s not like me, so I thought I’d better take it out of the wastepaper basket and have another look. And I did and went back to LA and met Robert Zemeckis and that was that.” It’s hard to imagine anyone else in the role of Doc Brown. Producers tend to agree. Since the movies, Lloyd has reprised his role in voice work for cartoons and video games based, because who else could sound like Doc Brown?
