Nathan Fillion's Green Lantern Is a 'Jerk' In James Gunn's Upcoming Superman: 'You Don't Have To Be Good'

A fresh take on Superman is on the way from visionary director James Gunn, and with it comes a unique portrayal of Green Lantern by Nathan Fillion. In a recent interview with TV Guide, Fillion shared insights into how his character, Guy Gardner, will differ from previous iterations seen in films and TV shows. Unlike the more charming versions fans might be familiar with, Fillion's Gardner is described as a less likable figure.

"He's a jerk!" Fillion exclaimed. "What's important to know is, you don't have to be good to be a Green Lantern; you just have to be fearless. 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 superhero persona, noting a significant flaw. "I think if he has a superpower, it might be his overconfidence, in that he thinks he could take on Superman," he said. "He can't!"

This new Superman film marks the debut of a rebooted DC Cinematic Universe and will launch the first chapter titled "Gods and Monsters." Alongside this cinematic venture, the Green Lanterns are also capturing attention on the small screen. HBO is currently producing a series called "Lanterns," featuring Kyle Chandler as Hal Jordan and Aaron Pierre as John Stewart, set 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. James Gunn, who wrote and directed the film, has scheduled its theatrical release for July 11, 2025.
