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 stays on the docket.
At MCM London 2026, he and Alan Tudyk dropped a small update on a possible Firefly return. There were no dates shared, there's no official commitment, just a hopeful hint instead.
Fillion also opened up about The Rookie. Crossover arcs are in motion with the North spinoff. The show's universe is slowly getting bigger with shared stories threaded across the spinoff.
He once did an A-list star impression to get out of a ticket. That A-list star's name went untold.
HBO's Lanterns team also chimed in. Fillion's Guy Gardner runs scenes next to Hal Jordan and John Stewart. The writers shared the logic.
