John Cena approves of Zac Efron’s ‘The Iron Claw’

John Cena has nothing to say but good for Zac Efron.

Zac Efron, who's The Iron Claw has already bagged a lot of praise, got “excellent” feedback from a real-life wrestler, John Cena.

Cena, who is starring together with Efron in the upcoming comedy Ricky Stanicky, lauded the star while talking to Entertainment Tonight.

"It was a real good treat to be able to go to the premiere of Iron Claw and see Zac do his thing -- especially from a lens that I'm familiar with," Cena said. "He did an excellent job."

And Efron seemed to feel like he got “everything” he ever hoped for, getting Cena's seal of approval on his performance.

"There's something special about when John's like, 'I know what you went through for that,'" Efron explained. "Not many people get it, so it's nice. It's pretty epic."

Ricky Stanicky, serving as writer-director Peter Farrelly's return to the comedy genre after directing classics like Dumb and Dumber and There's Something About Mary, acted as a resetting shift for Efron.

This came after his role in The Iron Claw, a film depicting the tragic real-life story of the Von Erich brothers.

"I didn't realize how much it was affecting me until I got back on set with these guys and started having fun again," the 17 again star admitted with a laugh. "I was like, oh man, I'm enjoying this process."
