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. Nothing was locked in, concrete plans are absent, only optimism to share.
Fillion also opened up about The Rookie. Storyline crossovers are planned with the North spinoff. The show's universe steadily broadens out with shared stories tied together loosely.
He once did an A-list star impression to get out of a ticket. The celebrity's identity went unspoken.
HBO's Lanterns team offered their take. Fillion's Guy Gardner crosses paths with Hal Jordan and John Stewart. The writers shared the logic.
