Rodriguez/Getty Images for CinemaCon John Cena can explain how he ended up in the Barbie cast. While on the Today show earlier this week to promote Fast X, the actor, 46, shared the story of how he wound up with a role in the upcoming Margot Robbie movie, calling it a "happy accident" that he "kind of" pitched himself. "I think Barbie and Fast X share a lot of parallels. Their cast lists are amazing. ... So with a lot of opportunity, it was a chance for maybe to, 'Hey, would you guys be willing to have me if I could do something?' " Cena told Hoda Kotb. "In an accidental run-in with Margot Robbie, I said, 'I will pretty much do whatever you guys need, 'cause I really enjoy the movie.' And they asked me if I wanted to be a merman. I said yeah, sure," he recalled. Cena, who worked with Robbie on 2021's The Suicide Squad, said the encounter happened when they "literally randomly ran into each other as friends," and Fast X was filming "across the street" from Barbie.

Helen Mirren is the narrator. Last year, Cena told British GQ about transitioning from WWE to Hollywood. "The term Hollywood has such a mystique and luster around it. If you're skilled at doing one thing, and then you transition into doing another — really, it sounds the same, but it's a completely different thing," he said. "If you have any chance of success, you have to really, really prepare as much as you can. And if you feel you don't have a head start, you've just got to put rubber to the road and work your ass off. So that's kind of where I'm at, dipping my toes back into the screen side of entertainment rather than live events." Cena added, "And I realize I've got my work to do, and I'm just trying to work as hard as I can to catch up to everybody else." Fast X is in theaters Friday.
