That is one awesome book trailer. Abraham Lincoln: Vampire Hunter is written by Seth Grahame-Smith, author of the best selling Pride and Prejudice and Zombies.
Now it's also to be a movie. Tim Burton just purchased the book, and will be working with his fellow producer from the animated film, 9, Timur Bekmambetov (Wanted). Grahame-Smith will adapt the screenplay from his own book.
Lincoln experienced a lot of tragedy in his life, and Grahame-Smith reimagines that it was all due to vampires. The Axe is Lincoln's weapon of choice, and he hides it in his long coat.
His Zombie book is also to be a movie, with Natalie Portman attached to direct.
