Project has New Line 'Thinking'

Leslie Mann, Elizabeth Banks attached to star in comedy

New Line has picked up "What Was I Thinking?" a comedy project from Susanna Fogel and Joni Lefkowitz with Leslie Mann and Elizabeth Banks attached to star. Lynda Obst is producing.

The project is based on a book of the same name which saw Barbara Davilman and Liz Dubelman compile 58 bad boyfriend stories. Obst saw the book and realized it would make a great hook for a movie. She then enlisted Fogel and Lefkowitz, who wrote the Sarah Jessica Parker HBO pilot "The Washingtonienne," to come up with a movie story.

The take sees a woman getting dumped during her engagement party, causing her friends to spring into action and whisk her away on a ski trip for healing and hedonism. Four flashbacks dealing in "worst ex-boyfriend" tales, threaded by the adventures on the ski trip, follow.

"It's a story of how women help each other," said Obst. "And we do that by telling stories." Obst also described the project as "a girls' Apatow movie."

Mann would play a woman who dates a lot but never seems to have serious relationships, while Banks is a woman on the rebound. Two other lead female parts are called for.

Michele Weiss and Merideth Finn are overseeing for New Line.

CAA-repped Mann co-stars in New Line's "17 Again," which opens tomorrow. After that, she appears in "Funny People," from husband Judd Apatow, as well as Robert Rodriguez's "Short" and "I Love You Phillip Morris," starring Jim Carrey and Ewan McGregor.

Banks, repped by UTA and Untitled, is coming off two comedies, "Zack and Miri Make a Porno" and "Role Models," and recently starred in horror movie "The Uninvited."

Fogel and Lefkowitz, who recently wrote "Little Darlings" for J.J. Abrams and Paramount, are repped by UTA and Brillstein Entertainment Partners.
