Nathan Fillion Joins James Gunn’s Superman as Green Lantern — Release Date, Cast, Plot & More

Fans Have a Big Week with Nathan Fillion: From Green Lantern Revelations to The Rookie Season 8 Delay Hollywood’s favorite everyman, Nathan Fillion, is dominating entertainment headlines this week thanks to two major developments: a candid peek at how he’s approaching Guy Gardner/Green Lantern in James Gunn’s upcoming Superman reboot and ABC’s surprising decision to push The Rookie Season 8 to mid-season 2026. Green Lantern Inspiration: Blanche Devereaux Meets Emerald Knight During a recent interview, Fillion stunned comic-book die-hards by admitting he’s channeling Golden Girls legend Estelle Getty—specifically her razor-sharp timing—as the core personality trait for his neon-ring-wielding Guy Gardner. The actor says Getty’s “bite-size confidence” helps him capture Gardner’s trademark swagger while keeping the humor grounded. Fillion also confirmed he lobbied hard for a comics-accurate bowl cut, ensuring the character’s visual throwback survives the big-screen update. DCU Double Duty: From Theaters to HBO The Green Lantern excitement doesn’t stop with Superman. Industry insiders report that Fillion will reprise Guy Gardner in HBO’s newly green-lit Lanterns series, allowing the Firefly alum to anchor the franchise across both film and streaming platforms. With Gunn steering the wider DCU, Fillion’s partnership positions him as a connective-tissue star similar to Marvel’s Samuel L. Jackson. The Rookie Season 8: Fans Cry “Fix This!” While superhero news electrifies social media, Fillion’s broadcast loyalists are venting frustration. ABC confirmed at its 2025 Upfronts that The Rookie Season 8 will skip fall 2025 and instead debut in winter 2026, citing a desire for an uninterrupted 18-episode run. The network’s Instagram announcement triggered thousands of comments demanding the procedural return sooner, with many noting the show’s consistent ratings growth. Why the Delay Could Help Fillion Although the hiatus disappoints viewers, it frees Fillion’s schedule to complete Superman reshoots and begin Lanterns principal photography without the juggling act that plagued previous seasons. Insiders suggest ABC negotiated the break to secure Fillion’s long-term commitment before his DCU profile skyrockets.
