Underworld (2003)

Underworld (2003) is a dark fantasy action-horror film directed by Len Wiseman, marking the beginning of the Underworld film series. The movie explores the centuries-long war between vampires and Lycans (werewolves), blending gothic horror elements with high-octane action sequences.
The story is set in a world where vampires and Lycans have been waging war for centuries. Selene, a vampire warrior known as a Death Dealer, specializes in hunting Lycans. She discovers a plot by the Lycans to capture a human, Michael Corvin, who holds a mysterious genetic secret that could allow the Lycans to create a hybrid powerful enough to end the war. As Selene delves deeper into the mystery, she begins to uncover hidden truths about the origins of the war, the manipulation of her kind, and her own past.
