It's a Boy Girl Thing

Pretty teen girl Nell (Samaire Armstrong) is extremely bookish and can't wait to move on to higher education, while her dim-witted neighbor and classmate, Woody (Kevin Zegers), wants nothing more than to play football. When a class trip to a museum places Nell and Woody under an ancient Incan spell, the two awake the next day to find that they've switched bodies. As they cope with their bizarre situation, Nell and Woody realize that they must discover a way to reverse the spell.
