Tom Cruise suited up for the New York premiere of Mission Impossible: Ghost Protocol. The stuntman has upped the ante in the franchise's fourth installment, dangling from the world's tallest tower in Dubai. But dare to ask the actor if there's a stunt he won't try. And when performing daredevil acts, Josh Holloway said he had it a lot easier than his co-star. Actor Simon Pegg who provided comedic relief in the action flick says Cruise isn't all business.
