The thought of Firefly returning sets every Browncoat’s heart racing, but Joss Whedon has ruled it out because everyone is busy with other projects. However, Tim Minear, former Firefly writer and producer, has other ideas. In an interview with EW, Minear acknowledges the challenge of reuniting the cast, but doesn’t rule it out:
I’m completely talking off the top of my head, but there’s a show that’s been on for the last couple years that’s reinvented the form in terms of the limited series. I’m trying to think of the name of that show — Oh yes! American Horror Story! It doesn’t have to be 13 episodes. Look how Sherlock does it.
It would still require an epic feat of coordination to get all the cast members as well as key players like Joss Whedon on set at the same time, but for a limited-run series, it feels much more plausible. Unlikely…but definitely plausible.
