Bitten

A 2008 Canadian black comedy vampire film, Bitten stars Jason Mewes as Jack, a lovelorn paramedic who rescues Danika (Erica Cox), a female vampire, from an alleyway. Jack and Danika try to find a way to feed her cravings to drink blood while killing as little as possible. When Danika becomes more violent, killing several people, including a young woman, Jack is forced to kill her with the help of Roger, his paramedic co-worker and friend, who stabs Danika in the heart to save Jack, resulting in Jack becoming a vampire himself.
