Subspecies is a Romanian-American direct-to-video vampire horror film series produced by Full Moon Studios and Castel Film Studios. The series ran from 1991 to 1998, and followed the exploits of the undead Radu Vladislas, portrayed by Anders Hove, and his efforts to turn Michelle Morgan (Denice Duff) into his fledgling. A spin-off film, Vampire Journals, was released in 1997, which featured characters that would go on to appear in the final installment. Ted Nicolaou wrote and directed all five films, including the spin-off.
