Teeth (18)

The worst date movie imaginable. Mitchell Lichtenstein – son of Roy, the American pop artist – has concocted a very strange blend of nerd romance and horror comedy that will make you either laugh or else choke on your popcorn.

Sweet-faced high-schooler Dawn (Jess Weixler) is struggling to deal with her inchoate sexuality when she discovers an extra complication: she is possessed of the mythical "vagina dentata", which castrates any man who penetrates her.

Whether a feminist revenge fantasy or a spoof on sexual repression, Teeth at least has the virtue of unexpectedness, though in detailing Dawn's tragicomic family life it bites off, ahem, rather more than it can chew.
