Variety reports that Scott Rudin and Fox Searchlight have acquired the screen rights for the Zoe Heller novel, which was released by Henry Holt this past August. "What Was She Thinking" is Heller's second novel; her previous effort was titled "Everything You Know." According to the industry paper, "What She Was Thinking" is a dark comedy that concerns a "61-year-old teacher-spinster [who] is drawn to a 35-year-old female colleague. . . The older woman takes a voyeuristic interest when her friend discloses she is having an affair with a 15-year old male student."

Producer Rudin and playwright Marber are also currently involved in the screen adaptation of Marber's award-winning play Closer. Rudin produced the four-person play on Broadway and in London and is also executive producing the film, which will star Jude Law, Julia Roberts, Natalie Portman and Clive Owens under the direction of Mike Nichols. Rudin also produced the film "Iris," which starred actress Dench.
