After two brooding, mysterious turns in Batman Begins (2005) and The Dark Knight (2008), Christian Bale gave his final performance as the Caped Crusader in The Dark KnightRises (2012). The road to becoming Batman wasn't been an easy one -- Bale himself confessed that bulking up to don the Batsuit the first time -- fresh off his emaciated take for The Machinist (2004) -- was no easy task. "When it actually came to building muscle, I was useless," the actor has said. "I couldn't do one push up the first day. All of the muscles were gone, so that was a real tough time of rebuilding all of that. But you have a deadline, you have an obligation. You've said that you will commit to this part, and I just can't live with myself for not really giving it as much as I can."
