BACK TO THE FUTURE 4 – First Trailer (2024) Tom Holland | Universal Pictures

Robert Zemeckis has stated that Back to the Future 4 will never happen, and while this is probably good news, there are some things which a sequel could have delivered. The Back to the Future trilogy came out between 1985 and 1990, and although there have been some calls for a sequel, many fans are content to leave it as it is. This makes Back to the Future a rare example of a franchise quitting while it was ahead, ensuring that it's legacy remains intact.

While Ghostbusters, Blade Runner, Top Gun and many more 1980s classics have received legacy sequels in recent years, Back to the Future is one franchise that seems untouchable. Legacy sequels and reboots have been hit-and-miss, so it may be for the best that Back to the Future remains in the past. Still, this means that all the untapped potential of a Back to the Future sequel will never be realized, and there are a few things that fans of Doc and Marty would have wanted to see.
