The Back to the Future trilogy has become one of the greatest movie trilogies to ever get made and, while there have been so many calls for a new instalment to get made, as well as rumours of a possible reboot, we have yet to see a Back to the Future 4 being made. However, actor Christopher Lloyd, who plays the role of Doc Brown in the Back to the Future movies, has admitted that he would be very interested in reprising the role for a future movie.
Lloyd shared, "I would love to do Doc again, no question. It’s tough to come up with an idea that contains the excitement of the original three. So 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."
As for Michael J. Fox being involved, Christopher added, "He’s just so warm and smart and has such courage coping with the Parkinson’s. He’s indomitable. He’s just great to be around. 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."
With all that said, it is highly unlikely that we will ever get to see another new Back to the Future movie, as Robert Zemeckis has made it perfectly clear that he will not allow there to be a reboot of the franchise, while also seeming very uninterested in making Back to the Future 4. We can still dream but it does not look promising.
