Tom Cruise must have had the power of Xenu in him when he performed this stunt.

You have to check out this incredible video from the filming of Mission: Impossible – Ghost Protocol, which shows Cruise performing an incredible stunt atop the world’s tallest skyscraper.

The 49-year-old jumps and climbs up the Burj Khalifa in Dubai via a suspension cord in the video, which is introduced by director Brad Bird.

Bird casually says: “This is just another day at work on Mission: Impossible.”

The video shows Cruise doing a number of takes on the side of the building – which is 2,723 feet high – including running up and down the tower and jumping from a window. Mission: Impossible – Ghost Protocol is released on December 16.
