There are many things to criticise Tom Cruise for - infact, most things in his life. But never let it be said that he isn't willing to put his money where his mouth is. No stuntmen for Thomas, oh no.. Look at this for complete, deranged lunacy.

Shot at the world's tallest building for Mission Impossible 4: Ghost Protocol, Tom goes running around the perimeter - HALF A MILE UP.

HALF A MILE.

What the actual fuck?

That must have cost more to insure than a 17 year old owning a Bentley in Peckham which is parked on the road at night. Jeez.

Props to you Tom. Still a nutjob, but a ballsy one at that.
