Casting a movie is a pretty big responsibility. If you make the right choice, the film could be a total hit, but if you choose wrong it could ruin the entire thing.
How many movies have you seen where you think of other actors who could have done it better? It seems like all your favorite actors are constantly fighting over the same parts, but they can't always win. Sometimes another actor is a better fit, while others may change their mind on the film. No matter the reasons why they didn't end up in the movie, it's got to be weird to watch another actor play the part you were fighting for.
These 21 actors were almost going to be in some of the most epic and classic movies around, but for one reason or another it didn't work out. Think of how different they would be!
Molly Ringwald as Vivian in 'Pretty Woman'
She says she doesn't specifically remember why she turned it down but is okay with the fact that she did because she says that "Julia Roberts is what makes that movie."
Reese Witherspoon as Cher in 'Clueless'
Resse Witherspoon was almost going to be Cher but when it came down to the wire Alicia Silverstone better fit the role.
Matthew McConaughey as Jack in 'Titanic'
Matthew McConaughey wasn't the only other actor considered for the role. Macaulay Culkin was also being considered before they cast Leonardo DiCaprio.
Christina Applegate as Elle Woods in 'Legally Blonde'
She turned down the role because she was afraid of playing another "dumb blonde" type role.
Will Smith as Neo in 'The Matrix'
Will Smith was offered the role but turned it down, making room for Keanu Reeves to jump in.
Charlize Theron as Roxie Hart in 'Chicago'
Charlize Theron was really excited to make this movie, but she was kicked off when the project switched directors.
Tom Selleck as Indiana Jones in 'Raiders of the Lost Ark'
Tom Selleck was going to play Indiana Jones but his schedule for Magnum P.I. wouldn't allow it.
Cameron Diaz as Mia in 'The Princess Diaries'
Cameron Diaz was apparently asked to play Mia but turned it down. It probably would have been a VERY different movie if she hadn't.
Jack Nicholson as Michael Coleone in 'The Godfather'
Nicholson said that he believed that he thought an actual Italian should play the character of Michael so he turned it down.
Tom Cruise as Ren in 'Footloose'
Tom Cruise was already signed to All The Right Moves when he was offered the role of Ren.
