“Underworld” is no ordinary horror movie. It tells the tale of a secret war between vampires and werewolves (or as they’re called here, lycans). Kate Beckinsale stars as Selene, a lethal assassin on the vampire side. Scott Speedman plays Michael Corvin, a man who finds himself wrapped up in this brutal war. This movie is rather well done, despite all the blood and graphic violence. The look of the movie is dark, Gothic and brooding, which fits very well with the story. The script is interesting, using science to bring the vampire and werewolf legends into the modern age (such as saying the lycans are allergic to silver). The story of the bitter rivalry between to two mythic characters would make a fascinating prequel, and the sequel should follow “Underworld” with real impact as well.
