Christian Bale
Bale was actually the perfect candidate to play Batman. His anger issues led to an outburst in 2009 that practically defined his entire career. He has always been cast as the tough, angry guy because that's who he is.
He Lost His Marbles
In 2009, Christian Bale blew up on his director of photography while he was shooting Terminator: Salvation. His words were extremely flagrant (that's why we're not repeating any of them here) but he seriously ripped into this guy. From then on out, Bale's career changed forever. If you want to learn more about this instance, google "Christian Bale freakout," but do be warned, there is plenty of foul languages.
