It's a Boy Girl Thing

Woody Deane (Kevin Zegers) and Nell Bedworth (Samaire Armstrong), life-long sworn enemies, wake up one day to find themselves in a very strange place: each other's bodies. In their switched identities, each sets about to destroy the other's high school reputation. When they start to succeed, they both get more than they bargained for.

Sometimes falling in love can be an out of body experience.
