Joaquin Phoenix may claim his crazy-person act was all part of a larger plan to promote 'I'm Still Here,' but it seems as though the actor's appetite for wild roles hasn't been appeased.

The Golden Globe winner is being eyed to play Abraham Lincoln's vampire-slaying instructor in the big-screen adaptation of Seth Grahame-Smith's 'Abraham Lincoln: Vampire Hunter.'

Deadline reports that the film, helmed by 'Wanted' director Timur Bekmambetov, has already attracted 'Flags of Our Fathers' star Benjamin Walker for the title role.
