Mission: Impossible has redefined what action cinema can be, and at its heart, one man has chased the impossible with fearless resolve. Tom Cruise, the eternal spy Ethan Hunt, has hung off cliffs, scaled skyscrapers and leapt from planes all in service of a franchise that never stops raising the bar.

Tom Cruise has run the gauntlet of on-screen stunts in the Mission: Impossible series. From HALO jumps at 25,000 feet to literally clinging to the side of a plane during takeoff, Cruise has put his body on the line as Ethan Hunt across seven movies and almost 30 years.

Tom Cruise opened up about how he prepares for his new "Mission: Impossible" stunts. In "The Final Reckoning," which hits theaters on May 23, the actor took on wing-walking.
