Embrace the Darkness (1999)

Angelina High and Kevin Spirtas are a vampire couple in Embrace the Darkness (1999), the tale of two L.A. neck nibblers who are recruiting volunteers for their personal blood drive. They need a few more mere mortals to join them, but they don't expect one of them to come between them—which is exactly what happens when Kev finds himself wanting to sink more than his teeth into Madison Clark. Naturally Angelina feels threatened by this new development, so naturally she decides to befriend—and then bed!—Mad. But as sure as Angelina is mad at her man, Mad is mad for Kev, who's promised her eternal life. Will this new duo live together forever in everlasting bliss, or will Angelina's sexy schemes ruin things?
