Showtime is adding some star power to its comedy pilot Insatiable, with Andie MacDowell, Lara Flynn Boyle, and Andrea Martin in negotiations to join the project.
The comedy, said to be in the tone of Twin Peaks, chronicles the intertwined stories of four families in a small town where everyone has some sort of addiction.
MacDowell will play the self-appointed first lady of the town, a glamorous, sophisticated woman who is married to a millionaire and is an eBay shopping addict.
Boyle will play MacDowell's character's sister, a local news personality married to a doctor who gets a sexual rush from stealing things.
Martin will play a loving and good-natured single mom and a hardworking accountant who is a gambling addict.
The three join previously cast Peter Facinelli and Beth Riesgraf.
MacDowell most recently was among the voice cast in the animated feature Barnyard. Boyle starred in the Lifetime TV movie The House Next Door and had a recurring role on NBC's Las Vegas. Tony winner Martin most recently was seen in the feature How to Eat Fried Worms.
