Sarah Chalke is Lifetime's 'Maneater'

Miniseries is based on Gigi Levangie Grazer's book

Sarah Chalke has signed to star in Lifetime's four-hour miniseries "Maneater," based on Gigi Levangie Grazer's book.

In addition, Timothy Busfield has come on board to direct the Sony Pictures Television-produced mini, which is being adapted by Suzanne Martin ("Frasier").

"Maneater," airing next year, centers on Clarissa Alpert (Chalke), a shallow thirtysomething socialite in a panic because she's still single. Setting her sights on a Hollywood producer, Clarissa puts into motion a plan to land herself a husband.

Martin and Grazer ("The Starter Wife") are exec producing "Maneater" with 3 Arts' Stephanie Davis.

"Scrubs" co-star Chalke worked with Lifetime on the movie "Why I Wore Lipstick to My Mastectomy."

Busfield has directed episodes of "Lipstick Jungle," "Las Vegas" and "Ed." He also served as executive producer on "Jungle."
