Then comes over 100 standard parachute jumps so they can practice the scene in the air and get the filming right because remember, Cruise isn’t the only guy making this jump.
There’s also a guy with a camera who has to do everything Tom Cruise does, only backward and with a camera strapped to his face.
First, the movie has to build a massive wind tunnel so everybody can rehearse what Tom Cruise actually needs to do while in the air.
Jumping out of airplane around 25,000 feet in the air is certainly a Mission: Impossible worthy stunt, but the work that went into shooting this one scene was just nuts.
