According to The Hollywood Reporter the Sci Fi Channel has cancelled its prescription for the comic book-based Painkiller Jane after one 22-episode season.  Sixteen of the Painkiller Jane episodes have aired already and the final six will run as planned with the show ending its run on September 21st.  Based on the comic book series created by Joe Quesada and Jimmy Palmiotti, the TV series starred Kristanna Loken as the government agent with amazing regenerative powers.

Painkiller Jane aired as part of the Sci Fi Channel's Friday night lineup once dominated by Battlestar Galactica, which took its ratings clout to Sunday nights early this year.  The Sci Fi Channel's new Flash Gordon series (see 'Inkworks Gets Flash Gordon'), which debuted last Friday night, earned the cable and satellite channel's best debut ratings of 2007.
