Do you like action and horror films?
Then you should watch the film Underworld.
The film is about a war of vampires and lycanthropes. The vampire Selene (Kate Beckinsale) is motivated because lycanthropes slaughtered her family when she was a child.
The leader of lycanthropes is Lucian and he must kill the survivors of a war of the past, Viktor and Markus. He investigated hybrids (mixture of vampires and lycanthropes).
Selene determines that the lycanthropes may have been following a human, Michael Corvin (Scott Speedman) and continues her investigation about the plans of her enemies.
Underworld is a good film and has got a very good plot. If you like fantastic films I think you should see it.
