Genius (1999)

Charlie, science wiz, hockey lover, and all around genius, is tired of being friendless. It's bad enough that he's in college before he's 14 helping a scientist who's in the midst of trying to defy gravity. So, in order to make his life exactly how he wants it, Charlie reinvents himself by taking on the image of a slacker/bad boy and enrolls in the local Jr. high. But juggling two lives is tough, even for a genius.
