Showtime is setting some new cast members for their new comedy, Insatiable.

Andie MacDowell, Lara Flynn Boyle, and Andrea Martin have joined the cast of the show The Hollywood Reporter describes in the tone of Twin Peaks; it 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.

Look for Insatiable on Showtime sometime next year.
