Nathan Fillion told Collider that his top sci-fi franchise isn't what fans might expect, and it has to be something other than Firefly. He stayed vague about it, so the reveal remains pending.
At MCM London 2026, he and Tudyk shared a quick word on a possible Firefly return. Details stay slim, everything is tentative, just a glimmer of possibility.
Fillion also discussed The Rookie. Crossover arcs are in motion with the North spinoff. The show's universe is gradually stretching wider with shared stories connecting the shows.
He once mimicked a major star to get out of a ticket. He kept the star's name hidden.
HBO's Lanterns team offered their take. Fillion's Guy Gardner shares a beat with Hal Jordan and John Stewart. The writers shared the logic.
