Tom Cruise has finally met his match!

The action star is known for doing his own daring stunts, but for Mission: Impossible - Rogue Nation he wasn't the only fearless actor on set. Co-star Rebecca Ferguson proved to be every bit the equal of Ethan Hunt.

"[My character] is the feminine version of Ethan Hunt," Rebecca told ET. "She has a kick-ass mean side and a vulnerability -- very much like me."

In the fifth Mission: Impossible film, out now, Ethan and his team are tasked with eradicating the Syndicate, an international rogue organization out to dismantle the IMF.

Tom said that he knew Rebecca was right for the job immediately.

"[Rebecca] is a bad ass," Tom told ET, recalling her audition. "She walked in the room and [director Christopher] McQuarrie and I were like ... she got the job."

What's more, Rebecca suffers from claustrophobia and vertigo, but she didn't let it stop her from doing a 75-foot cable drop with Tom on her first day.

"If Tom does it, I'll try it," Rebecca told ET.

This isn't her first time around the action-hero block. She co-starred opposite Dwayne "The Rock" Johnson in Hercules, but it was her role as Queen Elizabeth in The White Queen on Starz that made Tom want her for Rogue Nation.

"I've always loved Mission: Impossible," she said.
