Stunt gone wrong
During the chase scene across the London skyline, Tom Cruise was injured jumping from one building to another.
Although the actor successfully grabbed the edge of the second building - thanks to a safety harness and his extensive experience doing his own stunts - he fractured his ankle upon impact.
Despite the injury, Cruise got up and attempted to continue running to complete the shot. Filming was soon halted, and production was delayed for eight weeks to allow the actor time to recover.
Remarkably, the footage showing the moment of injury was used in both the film and its trailers. Cruise still refers to this particular stunt as “the easiest of all” he had to perform for the movie.
