Nathan Fillion told Collider that his top sci-fi franchise is something else entirely, and it is not Firefly. He hasn't disclosed the answer yet, so the reveal remains pending.
At MCM London 2026, he and Alan Tudyk dropped a small update on a possible Firefly return. There were no dates shared, concrete plans are absent, just a hopeful hint instead.
Fillion also talked shop on The Rookie. He teased crossover plans with the North spinoff. The show's universe steadily broadens out with shared stories threaded across the spinoff.
He once did an A-list star impression to get out of a ticket. He kept the star's name hidden.
HBO's Lanterns team weighed in too. Fillion's Guy Gardner teams up alongside Hal Jordan and John Stewart. The writers broke down the approach.
