IGN TV: So a quick question about Whedon - Have you said to him, "What are you doing next?"
Fillion: I'll actually tell you this. Two days after Joss finished writing Wonder Woman, which he's no longer doing, but he'd just finished writing it, I sent him an email that said, "Okay, you've had two days to relax, let's start thinking about your next project." So I threw this idea at him which somebody else has already bought and has the money for I'm sure. I wrote a couple scenes of this one particular project that I thought would be really cool and I said, "You writing it and making it awesome. You directing and me starring in it. Let's go. Let's run with this."
IGN TV: Can you tell us about it?
Fillion: I don't want to tell you because it's still in development. I've got my fingers in it and I want to be involved.
IGN TV: Can you give us a hint?
Fillion: It's a western. I can tell you that it's a western.
IGN TV: And you want Joss...
Fillion: I want it to be with Joss
LoS is dead and I'm the only other person that liked it. Hi!
Western? Hell yes.
Oh man, Firefly was awesome! I really hope that they go foward with the project. It sounds awesome.
