Movie Set has a number of movies in various stages of production. One of them is Blood: A Butcher’s Tale. Aaron Douglas (of Battlestar Galactica fame) plays Sam, a butcher who discovers that the love of his life is being seduced by a vampire. He then sets out to butcher (literally) the entire race of vampires. There is a lot of information about the movie (including the script) over on Movie Set.com. You can also read the script over on the movie scripts page.
Over on the unproduced scripts page there are five more scripts up for your reading pleasure. – Don
