Seriously, I take back everything I ever said about Tom Cruise. His acting anyway. The guy has always liked doing his own stunts in his movies, but nothing like this. Mission: Impossible-Ghost Protocol has been filming in Dubai, and already this looks to be the biggest one yet, literally. If you've never heard of the Burj Khalifa, just know that it's the tallest man made structure in the friggin' world at 2717 feet. One of the major action sequences has Cruise running alongside the face of the building and hurdling another actor. In action it could be a stunning set piece. Even the photos snapped of the shoot are thrilling. I can only imagine how it must've looked the bystanders watching from below. Check it out for yourself, courtesy of the Daily Mail.
