"Firefly" fans are in for a treat.

Nathan Fillion has just revealed at Awesome Con that an animated Firefly series is in advanced development based on the beloved cult sci-fi franchise—and Deadline has the details.

Fillion spoke on a panel at the Washington, D.C. event and live taping of his “Once We Were Spacemen” podcast alongside co-stars Alan Tudyk, Gina Torres, Jewel Staite, Morena Baccarin, Sean Maher, and Summer Glau, all of whom are expected to reprise their roles.

Adam Baldwin, who played Jayne Cobb, will also lend his voice to the project.

The animated reboot is being developed through Fillion’s production banner Collision33 in partnership with 20th Television Animation, which controls the underlying rights to the franchise.

Married writing-producing team Marc Guggenheim (DC’s Legends of Tomorrow, Arrow) and Tara Butters (Agent Carter, Reaper) are attached to serve as showrunners, and a script has been completed.

Joss Whedon, who created the original series, is not involved in the animated project. During today’s panel, Fillion confirmed Whedon has given the series his blessing.

The proposed series is set in the timeline between the original 2002 television run and its 2005 feature film continuation, Serenity, expanding the universe while preserving continuity with the established lore.

Early concept art has been developed in collaboration with the Oscar and Emmy-award-winning animation studio ShadowMachine, which can be found below. The fully assembled package is expected to be taken out to buyers shortly.

“The dedication of Firefly fans has kept this 25-year-old show relevant. Clearly, the return of Firefly is something the fans want. More importantly, it’s something they deserve,” Fillion tells Deadline.
