Ginger Snaps

Ginger Snaps is a 2000 Canadian supernatural horror film directed by John Fawcett and written by Karen Walton, from a story they jointly developed. The film stars Emily Perkins and Katharine Isabelle as Brigitte and Ginger Fitzgerald, two morbid teenage sisters whose relationship is tested when Ginger (who has started her period for the first time) is attacked and bitten by an unknown animal, and then later, during the next full moon, slowly starts to transform into a lycanthrope (werewolf). The supporting cast features Kris Lemche, Jesse Moss, Danielle Hampton, John Bourgeois, Peter Keleghan, and Mimi Rogers.
