If anyone knows the crazy world of sci-fi conventions, it's Nathan Fillion and Alan Tudyk.

The two actors starred together on Joss Whedon's short-lived, but cult-beloved "Firefly" (which went on to spawn the movie "Serenity"). The show and its stars are insanely popular on the sci-fi convention circuit, and it's an experience that Fillion and Tudyk plan to mine in a proposed web series titled "Con Man."

They just launched an Indiegogo campaign to finance the series. The plot is described thusly:

Wray Nerely (Alan Tudyk-Me!) was a co-star on Spectrum, a sci-fi series which was canceled -Too Soon- yet became a cult classic. Wray's good friend, Jack Moore (Nathan Fillion) starred in the series and has gone on to become a major movie star. While Jack enjoys the life of an A-lister, Wray tours the sci-fi circuit as a guest of conventions, comic book stores, and lots of pop culture events. The show will feature all the weird and crazy things that happen to Wray along the way to these events.

Their "Firefly" co-stars Gina Torres and Sean Maher are signed up to make appearances, as are other Whedonverse actors including Amy Acker, Seth Green, and Felicia Day.

Fillion and Tudyk hope to raise $425,000 to produce three 10-minute episodes, though Tudyk has scripts for 10 episodes. And to entice fans to fork over cash, Tudyk has teased that one installment is a "lost episode" of "Spectrum," and would feature both actors on a spaceship.

Maybe "Firefly" can't be resurrected, but this is pretty darn close!
