Mandy Ingber and Robyn Lively in Teen Witch.

As its theme song warns—or perhaps threatens—you’re never gonna be the same again after watching Teen Witch (1989). The phrase is emphatically repeated no fewer than 17 times in the track that accompanies the film’s baffling opening sequence, which plays like a ponderous perfume ad aimed at tweens. When that sonic nightmare is finally over, 15-year-old Louise Miller (Robyn Lively) awakens to find her little brother, Richie (Joshua John Miller), binge-eating junk food beneath her bed.

It is as difficult to convey Richie’s essential gayness as it is burdensome to adequately describe the many tortures of the Teen Witch soundtrack. Louise will soon learn, on the cusp of her sixteenth birthday, that she is a witch poised to assume control of her powers. But to focus solely on her supernatural gifts is to overlook the flaming young Richie’s demonic possession by the spirits of Paul Lynde and Alice Ghostley. Zelda Rubinstein plays Madame Serena, Louise’s mentor in mischievous magic, and I kept imagining her Poltergeist character spotting Richie and chanting “Cross over, homos. All are welcome!”
