In the 1980s, Steven Spielberg, Robert Zemeckis, and Bob Gale released the Back to the Future trilogy, a series about teenager Marty McFly and scientist Doc Brown as they travel to many different time periods using a time machine built in a DeLorean. When Back to the Future Part III was released in 1990, the film ended with a clear "The End."
And that's it.
Many fans have wanted a Back to the Future Part IV, but let's be clear: Not happening. Not in a million years. Another film has already been rumored countless times, but I know that as long as the director, writers, and producers are alive, they're not making another one.
On October 21, 2015, they released Back In Time, a Back to the Future documentary. I liked it and I even have the film poster as the background on my phone. At one point in the film, they discuss the very topic of making another film. Director and co-writer Robert Zemeckis says:
Writer Bob Gale once said, flatly:
"Let me answer one question before anyone asks it, which is 'Is there ever going to be a Back to the Future Part IV? No."
Christopher Lloyd, who portrayed Doc in the series, has thought otherwise, saying that he would reprise his role if the original cast and crew returned and it was a story worth telling.
Lloyd HAS in fact reprised the role in a short called Doc Brown Saves the World.
I also don't think that another movie would really capture the previous three films' magic because Michael J. Fox (Marty McFly) is 56 years old and Lloyd is 78. When the three films were released, Fox was in his 20s and Lloyd in his 40s and 50s. I could see Lea Thompson (Lorraine) and Tom Wilson (Biff) reprising their roles, but Crispin Glover (George) probably can't because of a feud going on between him and Bob Gale and Rob Zemeckis. That's why we never see George's face clearly in Back to the Future II and III. I don't think there should be Part IV, in my opinion.
But for now, check out Marty McFly and Doc Brown time traveling to the Jimmy Kimmel show a few months back.
