The critically well-received comedy "Party Down" ran for two seasons but suffered low ratings, EW.com said. Also, its stars, Adam Scott and Jane Lynch, left to appear on other shows, the Web site said.
"After careful consideration, we've decided not to continue on with subsequent seasons of 'Party Down' and 'Gravity,'" Executive Vice President of Programming Stephan Shelanski, said in a statement. "We're grateful to everyone involved in the shows, and are proud to have had them on the channel. Starz remains committed to aggressively expanding our original programming lineup."
