James Gunn ("Slither") is pulling together a new ultraproject merging some of the "Firefly" cast with some porn starlets says CHUD.

Actors Nathan Fillion, Alan Tudyk, Michael Rosenbaum, along with porn starlets Belladonna, Aria Giovanni, Jenna Haze, and Sasha Grey will star in the as yet unannounced project.

Gunn is presently working on "Humanzee", a short contribution to the Xbox Live series of comedy flicks by horror filmmakers. He's also co-hosting the reality show "Scream Queens" with "Saw" series star Shawnee Smith.
