Frank Grillo says he was left "surprised" by John Cena during their time working together on Peacemaker.

While attending the premiere for the show’s second season, the actor, 60, told PEOPLE that the WWE pro-wrestler turned actor, 48, delivered a performance that caught him off guard — in the best way.

“[I’ve] got to tell you, he surprised me the most because he's an amazing actor,” said Grillo. "What he does on this show, with this season specifically, he's got some heavy weights to lift.”

The second season of the HBO Max series will see Cena’s Peacemaker “face his traumatic past and take the future into his own hands” as he “discovers an alternate world where life is everything he wishes it could be,” according to an official synopsis.

Grillo, who plays Rick Flag Sr. — someone who finds himself at odds with Peacemaker — said that the “material’s heavy” for the second season, but despite this, Cena stepped up and delivered.

The Resurrection of Charles Manson star added that his admiration for Cena goes beyond his acting talent. As he explained, his costar was also an exceptionally genuine person to be around.“He's maybe the nicest guy I've ever met in my life,” Grillo told PEOPLE.

His sentiments also extended to the rest of the show's stars.

"It’s an amazingly deep cast. Like, everyone is really great and accomplished. So, I've had a ball with everyone. I really have. They're all amazing," Grillo said.

Grillo wasn’t the only one who praised Cena on the red carpet.

Jennifer Holland, who plays Emilia Harcourt on the show, said that it has been “amazing” getting to work with the Heads of State star.
