Back To The Future’s Original Cast & Why 3 Actors Were Replaced

The original Back to the Future movie kick-started a franchise that remains one of the most popular in film history to this day, but three actors replaced from the original cast would have made for a much different movie if those actors had remained in the parts. Part of the reason why the franchise grossed almost one billion dollars over three films is the strong relationships that exist between the stars, between the protagonists and antagonists, and each of the supporting pieces. Director Robert Zemeckis was able to find the right chemistry with the right performers, but it did take some time to get the right people in place.
