Video footage shows the mega-star -who always performs his own stunts - take a huge leap off some rigging onto a rooftop opposite while strapped into a harness.
However, the 55-year-old misjudges the jump and slams into the building, leaving him momentarily hanging in the air.
Clearly shocked, Tom pulls himself up onto the rooftop and staggers towards the crew.
After taking a moment to regain his composure, Tom then limps away and holds onto his knee while wincing in pain.
