What if your favorite character had been portrayed by a completely different actor than the one you’re familiar with? Would you still feel the same way about the movie? Most movie productions go through a long casting process before they’re able to find the right person for the lead. In some cases, recasts take place just before, or sometimes during filming. Whether because of differences of opinion with the director, poor acting skills, or prior obligations, some actors just don’t work out.
Here's some roles actors/actresses passed on, and some that were recasted. Some for the better, others not.

Ice Cube and Dave Chapelle as Bubba
Forrest Gump
Chappelle was offered the role of Benjamin Buford "Bubba" Blue in Forrest Gump. Concerned the character was demeaning and the movie would bomb, he turned down the part. He has since said that he regrets not taking the role when he saw how successful the movie became. Appearing in Forrest Gump would have introduced Dave Chappelle to an extremely large, mainstream audience early on, but the movie isn't exactly in tune with the tone of his stand-up. A role in a huge movie like this would have been great for Chappelle’s acting career, but it might have proved to be a distraction from his comedy.
Ice Cube turned down the role of Bubba because he did not want to appear "stupid."
