Tom Cruise takes on the tallest building in the world

Tom Cruise is either one of the bravest men on the planet – or one of the craziest. The 48-year-old star spent the weekend filming scenes for the fourth Mission Impossible film, which had him hanging from a wire near the observation deck on the 124th floor of Dubai’s super-skyscraper, Burj Kahlifa (pictured) – the tallest building in the world.  According to London’s Daily Mail, the actor “ran across the windows of the towers as nervous crewmembers looked on from nearby open windows.” This summer, Cruise to The Daily Record: “There’s always that adrenaline before you do a stunt… I want to entertain the audience, and part of making these movies is doing my own stunts.”
