Trivia: Tom Cruise broke his ankle doing the building jump in London. He was always intended to almost miss the landing and have to pull himself up, but his foot hit the side of the building and was forcibly bent at a wrong angle. Filming was held up for seven weeks. When he limps away once he has climbed up to the roof, he's not acting - that's the result of his injury.
Trivia: Henry Caville sports pretty prominent facial hair throughout the film. He was actually contractually forbidden from shaving it off for the sake of continuity. As a result, he had to film reshoots for "Justice League" with a mustache and heavy stubble, and that film was forced to use (unfortunately obvious) CG effects to remove them.TedStixon
Trivia: The man Tom Cruise and Henry Cavill fight in the bathroom is Liang Yang, a wushu champion. He was the stunt double for Emily Blunt in Edge of Tomorrow, also starring Tom Cruise and written by Christopher McQuarrie. He also played FN-2199 in Star Wars: The Force Awakens, who shouts "traitor!" at Finn.Jon Sandys
