Even though the film’s been shooting for a couple of weeks at least now, the cast for Abraham Lincoln: Vampire Hunter has just increased by a factor of one. And Abe now has a nemesis in the form of evil vampire Adam, played by Rufus Sewell.

Adapted by Seth Grahame-Smith from his own genre-mash novel, Lincoln finds the 16th president of the United States (Benjamin Walker) battling the undead and slave-owning southerners in his campaign against injustice and blood-sucking fiends.

We meet the young Lincoln as his mother his slaughtered by the vamps, and he swears revenge. He’s tutored in the noble art of slaying the creatures by friendly fang club member Henry Sturgess (Dominic Cooper) and also ends up meeting his future wife, Mary (Mary Elizabeth Winstead).

The film will delve into the idea that the vampire conflict was one of the real reasons the Civil War started. With Tim Burton producing and Timur Bekmambetov calling the shots, Abraham Lincoln: Vampire Hunter will be out on August 22 next year.
