Did you know that in Django Unchained

Did you catch this in Django Unchained? The picture is rife with Easter eggs that pay homage to the director's body of work, some of which are really subtle. "Minnesota Clay" is the name of a 1966 Corbucci Western featuring Cameron Mitchell in the titular role, and it is also the name of the bar that Django and Dr. King visit in the first town they arrive on horseback.
