The Underworld series gets the prequel treatment with this third outing that fleshes out the story of the ancient war between the vampiric Death Dealers and their wolfman counterparts, the Lycans. F/X technician Patrick Tatopoulos (Godzilla, Independence Day) steps out of the effects lab and into the director's chair with this entry, which sees stars Bill Nighy returning as Viktor, the King of his vampire clan and father to Sonja (Rhona Mitra), a free-minded heir who tests her parent by heading outside of their castle's borders and doing battle with the ravenous werewolves of the surrounding area. Sonja also harbors a secret love affair with Lucien (Michael Sheen), the first of the Lycans, a race of lycanthropes who were bred by the vampires to be slaves and protectors to the bloodsucking clan. As the news of their love spreads to Viktor, ranks of the vampire elite help Lucien escape, leading to a revolution of the Lycans against their masters and setting up the mythology of the later latexed adventures featured in Len Wiseman's two previous films.
