It's A Boy Girl Thing (2008)

In this body-swapping teen comedy, high school football star Woody (Kevin Zegers, TRANSAMERICA) and his chaste next-door-neighbor Nell (Samaire Armstrong, THE O.C.) wake up in each other's bodies. Now they get to experience what life is like on the other side–all the way from the football field to the girls' locker room! Though they may have been sworn enemies in their former lives, the two will have team up to get back to normal… and maybe even fall in love? This fun film co-stars Sharon Osbourne and was produced by a man who knows a little bit about gender-bending, Elton John.
