The casting on Quentin Tarantino’s slave western Django Unchained just gets more and more eclectic. Deadline reports that Tarantino has lined up Kevin Costner to play Ace Woody, a sadistic slave trainer who works for the villainous Calvin Candie (Leonardo DiCaprio). Those two, along with Samuel L. Jackson’s crafty slave Stephen, are allied against Jamie Foxx’s Django and Christoph Waltz’s Dr. King Schultz, a German bounty hunter helping Django free his wife from Candie’s plantation. That wife is yet to be cast, though Deadline suggests Tarantino may go with a relative unknown. [Deadline]
