Parker Posey, best known as the Jackie-O worshipping incestuous sister in "The House of Yes", will be taking a stab at horror in the third "Blade" movie. Posey will play a vampire in the film, sharing the screen with good guy half-vamp Wesley Snipes and bad guy Dominic Purcell. The eclectic cast also includes screen babe Jessica Biel and WWE champ Michael Paul LeVesque, along with Kris Kristofferson returning as Abraham Whistler.
Though not a regular in the horror genre (her only horror role prior to "Trinity" being that of Jennifer Jolie in "Scream 3"), Posey is a well-known face in indie comedies. She was nominated for a Golden Globe for her portrayal of Jinger Heath in the TV movie "Hell on Heels: The Battle of Mary Kay". She'll be seen next in the romantic comedy "The Laws of Attraction".
