THIS POSTER FOR 'BIRTH OF A NATION' IS A PUNCH TO THE GUT

In Birth of a Nation, Nate Parker plays Nat Turner, a Virginia slave who led a rebellion of slaves and free blacks in 1831. The film swept Sundance and is already generating Oscar buzz.

On Friday, Parker tweeted out the upcoming film's poster—a powerful image of himself as Turner, with an American flag noose around his neck, tears in his eyes.
