Lycans (Underworld) – 2003

The action thriller Underworld introduced Kate Beckinsale to a new demographic. It also introduced the world to a grisly take on classic werewolves — lycans. Constantly at war with vampires, lycans are vicious, intelligent, shapeshifting creatures with piercing blue eyes and exceptional strength. In other words, not something you want to come across when you're alone at night.
