Watch the stunt that almost killed Tom Cruise

He's a Hollywood action man who takes pride in performing his own stunts.

But daredevil Tom Cruise came unstuck after he injured himself during a failed building jump stunt while filming Mission: Impossible 6 in London on Sunday.

Video footage has emerged showing the esteemed actor, 55, taking a gigantic leap off some rigging and onto a rooftop while attached to a harness, but his jump appears to fall short and he crashes into the side of a building.

However, the star - who has been in training for a year in order to carry out the extreme stunts needs for the next Mission Impossible installment - seems to fall short of the mark and smashes into the building before falling down its side.

Following his crash, Tom is then seen limping away and falling to his knees, before clutching onto his legs seeming in apparent pain.

As the video ends, he is helped away from the set by stunt professionals.

MailOnline has contacted representatives for Tom for comment.
