Nathan Fillion told Collider that his top sci-fi franchise is a surprising choice, and it isn't Firefly. He kept the name quiet for now, so the reveal remains pending.
At MCM London 2026, he and Alan Tudyk dropped a small update on a possible Firefly return. Solid plans still missing, there's no official commitment, just fans keeping fingers crossed.
Fillion also discussed The Rookie. Storyline crossovers are planned with the North spinoff. The show's universe keeps expanding a little with shared stories threaded across the spinoff.
He once pulled off a celebrity impression to get out of a ticket. He kept the star's name hidden.
HBO's Lanterns team joined the chatter. Fillion's Guy Gardner teams up alongside Hal Jordan and John Stewart. The writers laid out the thinking.
