Logo for a sequel that was never made to a beloved franchise

Back To The Future IV was an unplanned sequel to Back To The Future III and was the proposed final chapter in the franchise due to Robert Zemeckis stating that he was done with the series and that Michael J. Fox is diagnosed with Parkinson's Disease. There were talks of making it in the mid 1990s, but was never made. However, Christopher Lloyd expressed interest in starring in the unmade film for many years.

  • Thomas F. Wilson as Biff Tannen
  • Lea Thompson as Lorraine McFly

Why It Was CancelledEdit

  1. After the release of Part III, Robert Zemeckis and the other filmmakers stated that the series was over as shown in the picture on the right and Zemeckis said that he was finished making Back To The Future films:
No Part IV

2. Michael J. Fox is too old to play our protagonist and has Parkinson's Disease.


The film was never made and was cancelled for good. However, there have been various trailers made by fans of the films. In 1991, a year after Part III was made, Universal made an animated series.
