Teen Witch (1989)

High-school nerd Louise Miller (Robyn Lively) learns from psychic Madame Serena (Zelda Rubinstein) that she's possessed with magical abilities that will begin working on her 16th birthday. When the prophecy proves true, the teenager uses her new powers to get what she's always desired: popularity. After getting back at some bullies, the young witch casts a spell over hunky jock Brad Powell (Dan Gauthier). But Louise soon learns that getting what you want isn't all it's cracked up to be.
