Tom Cruise sits on top of world's tallest building for Mission Impossible [Real or Fake]

The actor has been snapped perched precariously on a box at the very top of the 829m (2,723ft) Burj Khalifa in Dubai dressed in a grey T-shirt and jeans.

Daredevil Cruise was so carefree he wasn't even wearing any shoes.

And if you're starting to doubt the authenticity of the photo, a video has been released showing Cruise casually sitting on the top with a yellow helicopter flying above him.

Filmmakers reportedly had to monitor temperatures on the building's sun-baked surface so he wouldn't get burned while Cruise also had to be careful of cross winds.

Tom said at a press conference: 'I had to figure out, actually, how to fly. I had to figure out how to use my feet as a rudder ... The first couple of times I was slamming into the building.'

When asked what his first thought was he jumped of the building, he replied: 'I hope I don't fall.'

He previously told Empire magazine that he hoped the stunt would be the movie's 'popcorn moment'.

'I came banging into the building and I can literally feel the fear emanating from the crew and I’m like, “No, no, I’m okay, I’m okay!”We talked a lot about “popcorn moments”. You know, where you want to grab your popcorn. That’s what I always hoped Mission would be for an audience. And I really think we’ve nailed it.’

Mission: Impossible - Ghost Protocol is released in UK cinemas on December 26.
