Turning Down Bubba
As it turns out, John Travolta wasn’t the only one to turn down a major role in this film that ended up making major bucks in the box office. Several other big names had the chance to play Forrest’s friend Bubba but chose not to. Some of the actors that turned down the role of Bubba were Ice Cube, David Alan Grier, and Dave Chappelle.

And each actor had a reason for declining the part. Ice Cube felt uncomfortable playing a disabled character. But Dave Chappelle said he just didn’t imagine the film doing all that well. Big mistake, fellas. And I gotta say, I can’t imagine in my wildest dreams seeing Dave Chappelle as Bubba. I think it would end up being just too funny and not at all dramatic.
