John Cena has revealed that it took less than a few seconds for James Gunn to shatter his vision of Peacemaker in The Suicide Squad. There is no doubt that Cena's Peacemaker has become one of the DC Universe's most unconventional antiheroes, combining military bravado, questionable morals, and an almost absurd commitment to his own idea of peace. But Christopher Smith could have turned out very differently had Cena's original vision for the character made it to the screen.

As it turns out, director James Gunn had something else in mind, and the actor recently revealed how one conversation on the set of The Suicide Squad changed everything.

During a recent appearance on the Happy Sad Confused podcast with Josh Horowitz, John Cena recalled asking Gunn whether he should read the Peacemaker comics before filming The Suicide Squad. Gunn told him no, explaining that he wanted to create his own interpretation of the character.

Cena, meanwhile, had already developed a very different idea. He imagined Peacemaker as a devoted patriot and freedom fighter, taking inspiration from the military disciplinarian played by Lee Ermey in Full Metal Jacket. He had carefully considered how someone like that would move and behave, even when nobody was watching. However, the first day of the shooting shattered everything Cena thought of just like that.

“Hey, just be a douchy bro-y Captain America,” Gunn told him.

Cena described the moment as pivotal, as he had prepared extensively for the role, but suddenly had to decide whether to defend his interpretation or trust the filmmaker who understood the bigger picture.

“I got two choices. I can fight for right what I want, which is selfish. Or I can take advice from the dude who sees the whole movie in his head,” Cena explained. He chose the latter, abandoning his original approach and embracing Gunn's vision.

The change helped establish the character's distinctive mix of swagger, immaturity, and misplaced righteousness, which would later become central to his solo HBO series.

And Cena's willingness to trust Gunn was not just a one-time decision on the set of The Suicide Squad; it became part of why the actor values their creative partnership.

Despite the dramatic change in direction, John Cena clearly has no regrets about trusting James Gunn. In the same conversation, the actor spoke warmly about their creative partnership and explained why he would happily return to the Peacemaker helmet whenever the opportunity arises.

“And when I put that helmet on, I told James, I'm like, ‘Dude, I will put this helmet on as long as you need me to,’” Cena said. He went on to praise the environment Gunn creates on set.

"He makes me a better performer, so I love being around him,” the former professional wrestler said.

For Cena, the experience goes beyond simply playing a popular DC character. Gunn's preparation and clear creative vision give the actor confidence that his performance is serving the story as a whole. And that trust has clearly paid off, turning what began as a radically different character interpretation into one of Cena's most recognizable roles, currently rumoured to be in Man of Tomorrow.
