The Trailer for Blood: The Last Vampire Trailer is online. Based on the cult anime series that despite having a trailer, has no official release date.
ShockTillYouDrop.com describes it:
In the film, demons have infested the earth and only one warrior stands between the dark and the light: Saya, a half-human, half-vampire samurai who preys on those who feast on human blood. Joining forces with the shadowy society known as the Council, Saya is dispatched to an American military base, where an intense series of swordfights leads her to the deadliest vampire of all. And now after 400 years, Saya’s final hunt is about to begin.
And here is the Trailer:
Now despite the synopsis sounding like Buffy the Vampire Slayer (single girl warrior against the hordes of vampires guided by Watchers.. er The Council) meets Blade (Half Vampire fighting against the darker side of her heritage), the trailer DOES make it look pretty damn good.
