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: The voice heard during the initial mission briefing is that of director Christopher McQuarrie.
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.
Trivia: Jeremy Renner was meant to reprise his role for the film, after appearing in the previous two movies, but he was unable to due to his commitments to the film "Avengers: Endgame." It has been hinted that his character Brandt might return in a future film, however.
Trivia: With this film, Solomon Lane became the first "Mission: Impossible" movie villain to appear in more than one film. He previously appeared in the prior film, "Rogue Nation."
Trivia: The cliff at the end is an actual place, 'Preikestolen', located in Norway.
Trivia: Henry Cavill's arm gun reload moment during the bathroom brawl with Tom Cruise was improvised.
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.
Trivia: Including practice and filming, Tom Cruise jumped out of a plane 106 times for the halo jump he performs in the film.
