Mission Impossible: Ghost Protocol trailer, Mark Wahlberg thinks Tom Cruise fakes stunts

Is Tom Cruise a fake? Is it all a stunt? We're talking about his work on the film set, obviously. Following on from the insane clip we posted of him running up the world's tallest building, Mark Wahlberg appeared on US radio claiming the Mission Impossible star utilises CGI and isn't really that ballsy after all. Fight, fight, fight! We bet Cruise would love to fight Marky Mark. To prove he's not a fake, obviously.
