Casts harden for comedy pilots By Nellie Andreeva March 10, 2008, ET Josh Cooke is set to star in the CBS comedy pilot "My Best Friend's Girl." Meanwhile, Nicole Sullivan has been tapped as the lead in the Lifetime comedy pilot "Rita Rocks," joined by Richard Ruccolo and Tisha Campbell Martin. Additionally, Erinn Hayes has landed the female lead in the CBS comedy pilot "Worst Week," and Kay Panabaker has joined NBC's comedy pilot "Zip." "Girl," from Sony, is a multicamera comedy about two male best friends who own a bike shop and whose relationship becomes complicated when one (Tim Peper) starts dating the ex-wife of the other (Cooke). Cooke recently played the male lead on the ABC comedy "Big Day." The multicamera "Rita," from Media Rights Capital, centers on Rita (Sullivan), an overworked wife and mother in the middle of a full-blown identity crisis who starts a garage band with her postal carrier Patty (Campbell Martin) as well as her neighbor. Ruccolo, repped by APA and Brillstein Entertainment Partners, will play Rita's husband, a handsome former jock who now spends his days working 9 to 5 in a jacket and tie. Sullivan is with Innovative and the Safran Co. "Worst," an American version of the BBC's "The Worst Week of My Life," centers on Sam (Kyle Bornheimer) and his rocky relationship with the parents of his fiancee (Hayes) during a family holiday. Hayes, who starred on Fox's "The Winner," is repped by Innovative and manager David Sweeney. "Zip," from Universal, centers on a guy (Steven Weber) with no money living in Beverly Hills who -- with the help of a colorful cast of accomplices -- concocts schemes to secure a glamorous lifestyle for his three children. Panabaker, repped by Coast to Coast and attorney Patrick Knapp, will play the oldest child, who is bright, somewhat jaded and tired of her father's scams.
