Brad Pitt and Tom Cruise once lit up the screen together and fans have long hoped for a reunion.

While Pitt is open to collaborating with Cruise again, he has one hilarious yet serious condition.

In a recent interview, Pitt spilled secrets about their past, praised Cruise’s daring spirit, and revealed why he’s keeping his feet firmly on the ground.

Before they were Hollywood icons with impressive resumes, Pitt and Cruise shared lighter moments off-camera.

Recalling their time on “Interview with the Vampire,” Pitt told E! News that they “used to race go-karts together after filming,” describing the memory as “so sweet.”

That nostalgic tone carried over when Pitt acknowledged Cruise’s recent praise of his upcoming film, “F1,” directed by Joseph Kosinski. “It was so sweet of [Tom],” he said.

Cruise, known for his high-octane roles, notably complimented Pitt’s dive into the fast-paced world of Formula 1 racing.

Despite their friendship, Pitt didn’t shy away from drawing the line when asked if he would team up with Cruise again.

“Well, I’m not gonna hang my -ss off airplanes and sh– like that,” Pitt joked. “So when he does something again that’s on the ground.”

That comment, while lighthearted, highlighted the stark difference between the two stars’ working styles, especially when it comes to stunts.

Cruise, of “Mission: Impossible” fame, has built a reputation for pushing the physical boundaries of his performances.

Hanging off a plane mid-flight is just another day at the office for Cruise, but the same can’t be said about Pitt.

Director Joseph Kosinski, who worked with Cruise on “Top Gun: Maverick,” echoed Brad Pitt’s sentiments in a GQ interview.

Comparing the two actors, he said, “Tom always pushes it to the limit, but at the same time is super capable and very skilled. They both have the natural talent for driving. But yeah, I could see Tom maybe scaring us a little bit more.”

Even “F1’s” action-vehicle supervisor, Graham Kelly, couldn’t hide his nerves.

“We’d have had a crash. Tom pushes it to the limit. I mean really to the limit. That terrifies me,” he said. “I’ve done loads of Mission: Impossibles with Tom and it’s the most stressful experience for someone like me building cars for him, doing stunts with him.”

He added, “Whereas Brad listens and he knows his abilities, and I think he’d be the first to say, ‘Yeah, I’m not going to do that.’”

Although Pitt isn’t jumping onto planes anytime soon, his upcoming film “F1” still promises jaw-dropping action.

Set for a June 27 release, the Apple Original follows Pitt as Sonny Hayes, a has-been Formula 1 racer staging a comeback.

The cast includes Kerry Condon, Javier Bardem, and Damson Idris as the cocky new teammate who challenges Hayes on and off the track.

Describing the film, Pitt told E! News, “It’s big, it’s huge. The driving is something off the charts, but on top of it, it’s really fun. And it’s funny and it’s kind of moving, I dare say.”

As for what it felt like to drive an actual F1 car, Pitt gushed, “I’ve tried to describe this feeling of downforce — it is something otherworldly. I’ve never had this experience anywhere else, not in a rollercoaster, not an aerobatic plane, nothing.”

Brad Pitt also waxed philosophical during the “F1” premiere in Mexico, noting how he has learned to move on from his mistakes.

During a chat with Entertainment Tonight, the superstar actor shared, “No matter the mistake, you know, you just learn from [it] and move on. It’ll lead to the next success.”

Pitt’s response came after he was asked about how he managed to stay grounded despite the numerous challenges and achievements in his life.

Although Pitt didn’t open up about his mistake, he hinted that one of the things that helped him overcome difficult moments was family.

He said, “At my age, I see how important it is to surround yourself with the people you know, the people you love, the people that love you back.”

Pitt concluded, “Friends, family, and that’s it. From there, we get to go make things. It’s a pretty simple, I think, equation.”
