“Firefly” stars Alan Tudyk and Nathan Fillion are launching a crowdfunding campaign on Indiegogo for a new web series, “Con Man.”

The series is a lighthearted take on the personalities, luminaries, comic book stores, and characters the duo have encountered during their years in the sci-fi community and convention circuit.

“If you’ve gone to a sci-fi convention, you’ve only seen half of it,” said Tudyk. “’Con Man’ delivers what convention ‘All-Access’ passes have only promised in the past. I’ve been to conventions from San Diego to Dubai and I have so many great experiences to share through the world of ‘Con Man.’ The sci-fi fans have changed my life and I want to give them a chance to see a new view of the world they built.”

The campaign is seeking $450,000 and has an April 9 deadline.

The campaign reached its $450,000 goal around midday on March 11, prompting Tudyk to introduce two stretch goals: at $500,000 (which has since been passed) backers gained access to private instagram accounts, and at $575,000, the duo will be able to fund a fourth episode.

Tudyk is writing, directing, starring, and providing craft services. Fillion is producing the series and starring along with fellow “Firefly” alums Sean Maher and Gina Torres, as well as James Gunn, Seth Green, Felicia Day, and Amy Acker. “Con Man” is also produced by PJ Haarsma.

In a meta nod to “Firefly,” Tudyk will portray Wray Nerely, the co-star of sci-fi series ‘Spectrum’ (in which he played the spaceship’s pilot) — which was cancelled before its time and eventually became a cult classic beloved by fans. Fillion will portray his good friend Jack Moore, who starred in the series and has gone on to become a major celebrity. 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 at these events.

The campaign will include perks such as an exclusive backer blog, posters, headshots, signed scripts and props, set visits, private screenings and the chance to be a background character on the series.
