The DC Universe under James Gunn commenced its journey in 2024 with the release of “Creature Commandoes” on television. In 2025, the first DCU movie, “Superman,” is set to soar into theaters. Featuring the Man of Steel as the central character, the film, starring David Corenswet as Superman, also introduces a host of other superheroes. Among them is Guy Gardner, portrayed by Nathan Fillion, who plays a Green Lantern from Earth. You can discover more about Guy Gardner through Looper’s video recap linked above.

Comic book enthusiasts are familiar with Guy as the Green Lantern sporting a rebellious streak, yet “Superman” marks his live-action debut, leaving casual viewers less acquainted with him. Guy’s journey in the superhero world began as Hal Jordan’s backup in the Green Lantern Corps. Despite his initial supporting role, he quickly established himself as a standout member. Known for his self-centered demeanor and difficult nature, Guy still steps up to do what’s right when needed, albeit with a touch of bravado.

Guy Gardner’s brash demeanor isn’t his only distinctive feature; his iconic bowl haircut draws immediate attention. So pivotal is this haircut that Nathan Fillion insisted it remain true to the comic depiction when he accepted the role. Moreover, Guy’s role in the DCU won’t be confined to just “Superman.” His character’s journey will extend further, particularly with his appearance in the upcoming HBO Max series “Lanterns,” slated for an early 2026 release.

Guy Gardner first appeared in 1968’s “Green Lantern” #59, but while he’s appeared in cartoons, animated movies, and video games in the decades since then, a live-action debut has been elusive. He was to appear in a cameo in 2011’s “Green Lantern,” but the scene was cut. From the little information the DCU has revealed about “Superman,” Guy will be a member of the Justice Gang alongside Hawkgirl (Isabela Merced) and Mister Terrific (Edi Gathegi).

The Justice Gang is a corporate superhero team backed by the head of LordTech, Maxwell Lord (Sean Gunn). Fillion’s portrayal of Guy (which he says is based in part on Estelle Getty’s character, Sophia, from “The Golden Girls”) leans heavily into his somewhat abrasive personality, as he explained while appearing on the DC Studios “Showcase” podcast. “Just whatever it is, there it is, he’s just gonna say it,” Fillion explained. “Part of his origin was he was at one point hit by a bus and was in a coma. So I just say that’s the thing that flipped the switch. That’s the thing that caused a little bit of brain damage. Now he’s just … off a little bit.”

Guy prefers to make constructs that are specifically useful in any given situation. That might mean his ring generates a boot to literally kick someone’s butt or a cosmic motorcycle to ride through the stars. From the trailers, it appears that Guy is on Superman’s side despite his corporate backing, and whatever happens in the film will likely influence “Lanterns.” “Superman” soars into theaters on July 11, 2025.
