Nathan Fillion told Collider that his top sci-fi franchise is something else entirely, and it isn't Firefly. He hasn't disclosed the answer yet, so the reveal is still on the way.
At MCM London 2026, he and Alan Tudyk dropped a small update on a possible Firefly return. Details stay slim, there's no official commitment, just fans keeping fingers crossed.
Fillion also talked shop on The Rookie. Crossovers are in the works with the North spinoff. The show's universe is slowly getting bigger with shared stories tied together loosely.
He shared a wild star impression story to get out of a ticket. He kept the star's name hidden.
HBO's Lanterns team weighed in too. Fillion's Guy Gardner crosses paths with Hal Jordan and John Stewart. The writers broke down the approach.
