Firefly aired for just one season in 2002 before Fox canceled it. In the 24 years since, the sci-fi show has skyrocketed in popularity and now fans are finally getting more. Nathan Fillion has announced that an animated Firefly series is currently in advanced development, Deadline first reported.

Fillion shared the news at AwesomeCon during a live taping of his podcast Once We Were Spacemen with his Firefly co-stars Gina Torres, Morena Baccarin, Summer Glau, Sean Maher, Jewel Staite and Alan Tudyk. Tudyk co-hosts the podcast, in which the duo look back at their careers and interview past coworkers. Each of the actors present at AwesomeCon are expected to voice the animated versions of their characters.

This isn’t one of those maybe one day it will happen announcements, with many steps already being taken. The animated reboot is under the direction of showrunners Tara Butters (Agent Carter, Reaper) and Marc Guggenheim (DC’s Legends of Tomorrow, Arrow) — original creator Joss Whedon is not involved, but has given his blessing. It has early concept art from ShadowMachine, an Oscar- and Emmy-winning animation studio. Fillion is producing the show through Collision33, his production company, and with 20th Television Animation. There’s even already a script in place.

According to Fillion, the one thing left is a home for the series. He and his co-stars took to Once We Were Spacemen‘s Instagram to provide more details and implore FireFly fans to show demand for the reboot.

Firefly took place in 2517, centuries after a universal civil war. It followed a group of people living aboard a transport ship, Serenity, flying through the galaxy. In 2005, the show got a sequel in the form of a movie, Serenity.
