In 2003, Moore co-starred with Allison Janney, Peter Gallagher and Trent Ford in the romantic comedy-drama "How to Deal", based on Sarah Dessen's novels "That Summer" and "Someone like You". She played Halley Martin, a cynical and rebellious seventeen-year-old who deals with falling in love with Macon Forrester (Ford), the new boy at her school and her relationships and issues with her family and friends. The film failed to find teenage audiences in the U.S. and grossed a total of $14 million domestically.
