During the first half-hour of "Mission: Impossible — Fallout" there’s a sequence that has everybody who has seen the film over the weekend buzzing. Tom Cruise and Henry Cavill do a HALO jump (high altitude low open) over Paris. Cruise and Cavill’s plan is to parachute right onto the roof of the Grand Palais des Champs-Élysees.
Chris McQuarrie explained to Deadline that the sequence was shot for real — Cruise and a DP with a head-mounted camera did over 100 jumps at magic hour to nail the sequence.
"A 30K feet jump out of a plane in which he tackles Henry Cavill’s character in mid-air, only to catch up with him again in the air and resuscitate the guy with his oxygen tank in free fall. Cruise jumped out of the plane 106 times to get it right, and the only place the production could pull the stunt off legally was in the air space above the United Arab Emirates. There are other highlights in Fallout, such as the Paris motorcycle chase and the scene where Cruise jumps across buildings (which resulted in him breaking his ankle). With all these breakneck speed scenes, audiences don’t even realize that Fallout is the longest M:I ever at 2 hours and 27 minutes."
