Nathan Fillion told Collider that his top sci-fi franchise is something else entirely, and it has to be something other than Firefly. He stayed vague about it, so the reveal is in the works.
At MCM London 2026, he and Tudyk shared a quick word on a possible Firefly return. There were no dates shared, there's no firm timeline, just fans keeping fingers crossed.
Fillion also chatted about The Rookie. Crossovers are in the works with the North spinoff. The show's universe keeps expanding a little with shared stories tied together loosely.
He recalled a famous-star impression to get out of a ticket. The famous name stayed off the record.
HBO's Lanterns team added their take. Fillion's Guy Gardner runs scenes next to Hal Jordan and John Stewart. The writers explained the reasoning.
