Underworld

Parents need to know that Underworld is a dark, violent horror movie about battles to the death between vampires and werewolves. Non-stop action results in one grisly scene after another. The film contains countless bloody killings, decapitations, impalements, up-close vampire fang attacks, gun battles, point-blank shootings, and numerous gory transitions from human form into monstrous animal creatures. A few strong words are sprinkled throughout ("bitch," multiple uses of "f--k," "s--t," "Jesus Christ"). Some characters smoke cigarettes, and it’s unclear whether vampires shown in a social setting multiple times are drinking red wine or blood.
