Tom cruise mission impossible skyscraperTom Cruise scaled the world's tallest building in Dubai, while doing a stunt for his upcoming 'Mission: Impossible' installment subtitled 'Ghost Protocol.'

Cruise was seen scaling the Burj Khalifa, the world's tallest man-made structure, which stands at 2,717 feet tall. The actor hung from the side of its observation deck, way up on the 124th floor, successfully pulling off a dangerous chase scene with another actor.

The 48-year-old actor is reprising the role of CIA agent Ethan Hunt for the fourth time, and the first time since 2006's 'Mission: Impossible 3.'

Cruise often insists on performing his own stunts for the film's intense action sequences, and just last month he was seen going down a zip line without his shirt for another stunt scene for the movie.
