John Cena's Barbie role confirmed in new CinemaCon footage

We now know who John Cena is playing in the Barbie movie – and it’s a unique Ken doll.

As revealed during this year’s CinemaCon presentation, Cena is playing a merman version of Ken. The last doll released in that line was Mattel’s King Ocean Ken doll in 2021. We already know that Dua Lipa is playing Mermaid Barbie in the Greta Gerwig-directed toy story, set for release on July 21.

New footage was also shown off at the Las Vegas event (via Vulture), which sees Margot Robbie’s Barbie head to the real world after encountering Kate McKinnon’s ‘Weird Barbie’. Unfortunately for Barbie, reality is a harsh place – and she is “repeatedly arrested”

"These actors can do anything," Gerwig said of her expansive cast, which includes the likes of Ryan Gosling, Kingsley Ben-Adir, Simu Liu, Issa Rae, and Emma Mackey . "They took it so seriously. The humor came from taking everything to heart and then playing it like it’s a drama. It was like watching Marlon Brando play Ken."

Cena, meanwhile, isn’t just content with living in a Barbie world. He’s next set to appear in Fast 10 – the penultimate chapter of the Fast Saga. The Peacemaker actor is also gearing up for a new action comedy with Jason Momoa, plus an Amazon movie with Simu Liu and Awkwafina.
