Anthony Mackie and Dominic Cooper have joined 20th Century Fox's Abraham Lincoln: Vampire Hunter. Mackie will play Will, Lincoln’s best friend who gets to take part in the killings. Cooper will play Henry. Who that is depends on whether you read the book or not. Considering I haven’t, I’m going to assume Henry is a good guy. A quick glance at Wikipedia confirms that Henry is indeed a good guy - a good vampire in fact - and the one that turns Honest Abe into a vampire at the end of the book, WHOOPS, spoiler alert!). These two join Benjamin Walker as Abraham Lincoln. Timur Bekmambetov will direct from a script by the novel's author Seth Grahame-Smith, while Tim Burton produces.
