While on the Today show in May to promote Fast X, Cena 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 at the time.

"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.
