Leslie Mann (“Knocked Up,” “17 Again”) and Elizabeth Banks (“Zack and Miri Make a Porno,” “Slither”) are attached to star in the comedy “What I Was I Thinking?” for New Line Cinema reports the trades.
Barbara Davilman and Liz Dubelman’s original novel compiles 58 bad boyfriend stories. Susanna Fogel and Joni Lefkowitz (HBO’s “The Washingtonienne”) penned the adaptation.
Their 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.
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.
Lynda Obst is producing.
