Superman is coming to theaters in July 2025, and comic book fans were dying to get a glimpse of it. Luckily, they did once the trailer dropped in December 2024. By the looks of it, James Gunn‘s rendition of the beloved superhero is an action-packed ride. Now that we saw Guy Gardner, a.k.a Green Lantern, we know he’s being played by actor Nathan Fillion!

During an April 2024 interview with Collider, Nathan recalled James offering him the role of Green Lantern while at a premiere party for their film The Suicide Squad. After seeing each other in a large crowd, Nathan congratulated the screenwriter and filmmaker, who asked the actor, “‘Hey, did Peter [Safran] tell you what we’ve got for you next?’ I said, ‘No, he hasn’t said.’ He looked around like someone was gonna be listening. We were in a throng of people, but he leaned over and said, ‘You’re gonna be Guy Gardner.’”

While describing Green Lantern, Nathan pointed to his “flaws,” which the actor said he “love[s] to lean into” when embracing new characters.

“Guy Gardner is 90 percent flawed and doesn’t care. That’s one of his flaws,” Nathan pointed out. “I think there’s a real freedom in playing that. So, for a guy who likes to play flaws and flawed people, Guy Gardner is a gold mine.”

In addition to The Suicide Squad, we’ve seen Nathan in many other projects! Hollywood Life rounded up a few facts about the Canadian-American actor, below.
