James Gunn's upcoming Superman film introduces a fresh take on the iconic superhero, and with it comes Nathan Fillion's portrayal of Green Lantern, specifically Guy Gardner. In a recent interview with TV Guide, Fillion shared insights into his unique interpretation of the character, revealing that his version of Gardner will be quite different from previous iterations seen on film and television.

"He's a jerk!" Fillion exclaimed, emphasizing that being a Green Lantern doesn't require goodness, just fearlessness. "So Guy Gardner is fearless, and he is not very good. He's not nice, which is very freeing as an actor because you just think to yourself, what is the most selfish, self-serving thing I can do in this moment? And that's the answer. That's what you do in that moment."

Fillion also highlighted Gardner's hubris, suggesting that his character's overconfidence might be his superpower. "I think if he has a superpower, it might be his overconfidence, in that he thinks he could take on Superman," Fillion noted. "He can't!"

This new Superman film marks the first entry in a completely rebooted DC Cinematic Universe, kicking off the inaugural chapter titled "Gods and Monsters." Alongside the film, HBO is developing a series called "Lanterns," which will explore other members of the Green Lantern Corps, featuring Kyle Chandler as Hal Jordan and Aaron Pierre as John Stewart. The series is slated to premiere in 2026.

The cast of Superman includes David Corenswet as Clark Kent, Rachel Brosnahan as Lois Lane, Milly Alcock as Supergirl, and Nicholas Hoult as Lex Luthor. Written and directed by James Gunn, the film is set to hit theaters on July 11, 2025.
