Steve McQueen, the legendary star behind such films as The Great Escape and Bullit, turned down the role of Sundance in Butch Cassidy and the Sundance Kid. The part instead went to Robert Redford. The film is an absolute classic, and spawned a legendary pairing between Paul Newman and Robert Redford, who would go on to do many award-winning films together. While McQueen may have regretted this decision, it’s hard to imagine that he could grow a better moustache than Redford. And based on McQueen’s numerous attempts to upstage Yul Brenner in The Magnificent Seven, it’s probably best that he turned down this role so that The Sting could be made.
