As many of you already know, Quentin Tarantino's films are all kind of connected in his crazy movie universe. Tarantino confirmed in a previous interview that a minor character from Django Unchained that is an ancestor of a character from one of his other films. He didn't reveal who the character was though. Now, thanks to Reddit user thefirerisesnolan (via Badass Digest), we know that when Tarantino says the the Django Unchained character was minor, he wasn't kidding. In fact the only thing we see of him is a name on a wanted poster, and that name is Crazy Craig Koons, who's related to Christopher Walken's Pulp Fiction character Captain Koons. Check out the picture below! Looks like Django ended up killing his great-great-great-granddad.
