Tom Cruise is known for doing out-of-this-world stunts in his movies, and Paramount has just released a featurette to take us behind the scenes of his latest feat for Mission: Impossible Fallout.

The Mission: Impossible franchise is iconic, and has some of the most instantly-recognizable stunt sequences in action films. Whether it’s Tom Cruise rappelling from a roof and stopping mere inches from the floor, hanging from a mountain, or riding outside an airplane as it takes off, it seems Cruise has done it all in his portrayal of IMF agent Ethan Hunt.

So when the team behind Mission: Impossible Fallout thought about creating a big stunt to push the envelope even further, they had to think pretty big. While a lot of the press surrounding the latest Mission: Impossible film has been around the stunt where Tom Cruise runs and leaps from one building to another (where he brutally broke his ankle), it wasn’t the biggest stunt of the film.

No, the big stunt of Fallout was, in fact, a pretty intense skydiving scene where Cruise performed what is known as a HALO (High Altitude Low Open) Jump. In this stunt, Cruise would be required to leap out of an airplane above 25,000 feet in the air (high altitude), and wait to open his chute until he was below 2,000 feet in the air (low open).

In military and espionage uses, HALO Jumps are meant to allow individuals to travel to extremely sensitive drop zones completely undetected thanks to that high jump and last-minute parachute deployment. However, in movies, it’s been such a risky move that no actor has ever attempted it before.

Unlike other skydives, the high altitude at the start requires that the jumper wears oxygen as they make their descent onto the earth. And timing the parachute deployment just right to have that covert landing without colliding with the earth is a delicate and risky move.

Added to the mix for Cruise’s jump, however, is that he’s also got to film it and perform a mid-air stunt during the entire affair. The featurette explains the logistics of filming such an impressive stunt, and it’s obvious bringing this HALO Jump to the big screen was a labor of love for Tom Cruise and the entire team.

It’s an impressive feat that Cruise has achieved, and we can’t wait to see the HALO Jump in action when Mission: Impossible Fallout hits theaters on July 27.
