As if hanging off the side of an airplane, climbing the world’s tallest building and jumping from one building to another (and actually breaking his ankle) wasn’t daring enough, according to Katy O’Brian, Tom Cruise’s stunts in the upcoming Mission: Impossible – The Final Reckoning film will be even more intense.

“Tom is always topping whatever he has done,” O’Brian — who stars in the film alongside Cruise, 62, — exclusively told Us Weekly while walking the Out100 red carpet in Los Angeles on Wednesday, December 11. “So, if you thought that little motorcycle stunt in the last movie was something, this is absolutely terrifying.”

In Mission: Impossible – Dead Reckoning Part One —the seventh film in the beloved franchise — Cruise drove a motorbike off the edge of a cliff, flew off the bike and then parachuted to the ground. In preparation for the film’s death-defying scene and to pull it off safely, Cruise reportedly trained with stunt coordinator Wade Eastwood for months.

“He’s wild! But I don’t think that anyone in the future of film will ever top what he has done,” the Love Lies Bleeding star continued.

The eighth film in the Mission Impossible franchise adds O’Brian to an already star-studded cast. Returning cast members include Hayley Atwell, Ving Rhames, Simon Pegg, Vanessa Kirby, Esai Morales, Pom Klementieff, Henry Czerny, Angela Bassett and Rolf Saxon. Christopher McQuarrie is also returning to direct.

O’Brian told Us about her experience joining the team.

“I think one of the things that I really loved was just how collaborative of an environment it was. Like Tom and McQuarrie, they trusted me almost the second that I came in there, and they really just built this amazing team,” The Mandalorian star said.

“Tom is standing behind the camera working with you the whole time. It’s kind of nuts,” she added. “He’s there in your face the whole time. So, I just think that’s excellent and they’re so passionate about it.”

O’Brian believes that after spending time with Cruise on the film, she’s earned a spot on the actor’s famous cake list, referring to the actor’s famous coconut cakes he sends to costars and friends during the holidays. Glen Powell, Jimmy Fallon, Henry Cavill, Kirsten Dunst and more have all reportedly received the so-called “Cruise cake.”

“I believe there’s one in the mail for me,” O’Brian told Us. “I can’t wait. I hope that’s [it]. I’m going to be really disappointed if I find out that it’s not what it is.”

Mission: Impossible — The Final Reckoning will be released in theaters on May 23, 2025.
