Joss Whedon has never heard of Ace Underhill.
Underhill said in an interview: “If [Joss] contacts me and says, ‘Hey, we’re not interested in Firefly anymore’ or ‘I’m not interested in Firefly anymore,’ then I will abandon the project
Underhill wants to do a pay per view model. That would be downloads to video ipod, pay per view television, etc. That model concerns me that the success would be limited.
Underhill added that he has contacted members of the Firefly/Serenity cast and had received a few rate quotes from agents, but he declined to say who. He acknowledged that he had not yet heard from Firefly/Serenity star Nathan Fillion.
The Browncoats have a discussion on this topic. Could be Underhill is just trying, and successfully, to get press for his company. I mentioned Underhill’s effort on Jan 23. See other Firefly posts.
