The Underworld movie series began with the 2003 action-horror film about the secret history of vampire and werewolves, where the latter are referred to as "Lycan" as an abbreviated form of lycanthrope. It is the first film in the Underworld series. The main plot revolves around Selene (Kate Beckinsale), a vampire "Death Dealer", or Lycan hunter, a job she is extremely good at due to her hatred for the whole species, whom she believes to have killed her entire family. She finds herself attracted to a medical intern, Michael Corvin (Scott Speedman), after saving him from the Lycan master Lucian (who bit Michael and infected him with the Lycan virus), and must decide whether to do her "duty" and kill him or to risk her life to save him. This movie has many parallels as a dark Romeo and Juliet tale.
