This past Saturday, October 30, Tom Cruise spent the day as his super-spy counterpart Ethan Hunt shooting scenes for 'Ghost Protocol,' the next installment in the 'Mission: Impossible' series. Fans gathered not just to get a peek at a real-life movie star, but also grit their teeth in terror, as they watched Cruise perform a mind-blowing stunt on the world's tallest building.

Standing at 2,717 foot, the Burj Khalifa -- located in Dubai -- is the world's tallest man-made structure, ever. Cruise hung from the side of its observation deck, way up on the 124th floor, and thumbed his nose at gravity, successfully pulling off a dangerous chase scene with another actor. A helicopter circled the actors mere feet away, while the crew shot the stunt from the floor above. His spokeswoman told the Daily Mail, "Tom has been preparing for the stunt for some time. He believes if he performs the stunts himself, the audience believes more in his character."
