10 WORST Actor Replacements In Movies

10. George McFly - Back to the Future Part II (1989)

Back to the Future Part II took audiences to the actual future for the first time in the series, sling-shotting Marty (Michael J Fox), Doc (Christopher Lloyd), and the DeLorean forward into the space-age world of, uhh, 2015... Shenanigans abound as the pair attempt to prevent both Marty's son (also played by Fox) from sabotaging the McFly family's future, and bully extraordinaire Biff Tannen (Thomas F. Wilson) from altering their history, culminating in a wacky return to 1955.

While the film is fun enough, the production and release were laden with almost as much controversy as the first movie (which saw the mid-filming firing of original Marty, Eric Stoltz), thanks to producers' unwise decision to replace Crispin Glover's George McFly with another actor (Jeffrey Weissman) wearing a face mould of Glover taken during the filming of the first Back to the Future. A major lawsuit trailed Part II upon its release, with a reported $760,000 pay-out for Glover.

Weissman, while not a bad actor, is not a good likeness for Crispin Glover and couldn't exactly play well through some creepy prosthetics while also being side-lined to make up for the switcheroo. Still, all this could have been avoided simply by paying Glover the initially rather high sum of $1 million he demanded to return to the role.
