They've turned into the things they hated most... each other.

It's A Boy Girl Thing is a brilliantly funny romantic comedy about next-door neighbours who live worlds apart. Woody Deane (Zegers) and Nell Bedworth (Armstrong) are life long sworn enemies who wake up one day to find themselves in a very strange place: each others bodies. In their switched identities, each sets out to destroy the other's high school reputation. When they start to succeed they get more that they bargained for. Sometimes falling in love can be an out of body experience.
