"I will be doing the Party Down movie," she said. "John [Enbom] is writing it right now."
Megan Mullally also added that the entire cast is coming back, with the possible exception of Jane Lynch, who she was not sure about. The story is said to pick up just where the second season finale left off.
"I think we're going to see Lydia's ex-husband -- Ed i think is name --- who was really racist and a misogynist," Megan Mullally said of her character's possible story line.
The show Party Down followed a hapless group of Los Angeles caterer-waiters and ran for 2 seasons and 20 episodes. It was created by John Enbom, Veronica Mars scribe Rob Thomas, Dan Etheridge and Paul Rudd.
Filming will take place late spring or early summer.
