Nathan Fillion's Green Lantern: A 'Jerk' in Gunn's Superman Film

James Gunn's upcoming Superman film introduces a fresh take on the iconic superhero, and with it comes Nathan Fillion's unique portrayal of Green Lantern, Guy Gardner. In a recent interview with TV Guide, Fillion shared insights into his character, revealing a stark departure from previous iterations. "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 further elaborated on Gardner's hubris, suggesting that his character's overconfidence might be his true 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 rebooted DC Cinematic Universe, kicking off the inaugural chapter titled "Gods and Monsters." Alongside this cinematic venture, HBO is developing a series called "Lanterns," focusing on other members of the Green Lantern Corps, with 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.
