It's Official.

From TPTB at savefarscape.com

Savefarscape.com is now free to confirm that the rumors swirling have their basis in fact. Farscape, cancelled last year by the SCI FI Channel, will return as a 4 hour mini-series. While we can't currently name the source of this information, please know that we wouldn't post this news without a trustworthy and solid source. Also, please note that the Jim Henson Company has made no official announcement as of yet.
Filming will begin in December and the mini-series is expected to air next year. There is no current word on distribution. Ben Browder and Claudia Black will reprise their roles as Commander John Crichton and Officer Aeryn Sun.

A Jim Henson Company production, Farscape was aired for four seasons on the SCI FI Channel before being cancelled in September 2002. The fourth season finale and last new episode aired at the end of March 2003.

The fans reacted immediately to news of the cancellation and began one of the most impressive fan campaigns in television history. Through a strength of spirit and ideals of community and family, the fans of Farscape have created something fabulous and achieved something that should have been impossible.

Take a bow Scapers, you did it. You saved Farscape and don't let anybody tell you differently. This is all yours. You kept the hope alive, you kept Farscape alive, until the people behind Farscape could get back to work on telling us the rest of the tale again.
