Back to the Future trilogy co-writer explains why there will never be a Back to the Future 4. Robert Zemeckis’ Back to the Future franchise cemented itself as a global phenomenon since the first film’s release in 1985. Marty McFly’s (Michael J. Fox) time-traveling adventures with his scientist friend Doc Brown (Christopher Lloyd) in his DeLorean time machine had a significant effect on pop culture and is still often referenced in movies and TV shows today.

Since the third film’s release in 1990, many fans have wondered about a fourth installment. All three films were box office successes, with Back to the Future Part II widely regarded as one of the best sequels of all time. While many believe a fourth film would not be able to live up to the trilogy, there has been discussion for a while among fans about the possibility of a continuation. Tom Holland even revealed that talks of a reboot or a remake have occurred at one point. However, with Fox semi-retired from acting since his diagnosis of Parkinson’s, the likelihood of a reboot was pretty slim. Now, it’s confirmed that it will never be made.
