Tom Cruise Gets Real High on the ‘Mission: Impossible 4′ Set (VIDEO)

You gotta give Tom Cruise credit: He’ll go to any lengths—or heights—for whatever project he finds himself working on.

The 48-year-old Top Gun star was recently spotted doing his own stunts for the upcoming Mission: Impossible 4, climbing the outside of Dubai’s Burj Khalifa skyscraper, which just happens to be the tallest building in the world. 

How tall? 2,717 feet tall. And Cruise even takes time out to give a friendly wave to the lucky tourist who spotted him at work from the building’s observation deck.

Check out Cruise’s act of professional bravery in the video below. (WARNING: If you have a fear of heights, you might want to skip this one.)
