Nathan Fillion told Collider that his top sci-fi franchise is something else entirely, and it isn't Firefly. He held back the title, so the reveal remains pending.
At MCM London 2026, he and his co-star chimed in on a possible Firefly return. Nothing was locked in, there's no firm timeline, just fans keeping fingers crossed.
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 tied together loosely.
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 joined the chatter. Fillion's Guy Gardner teams up alongside Hal Jordan and John Stewart. The writers laid out the thinking.
