It appears that Kevin Costner won’t be starring in Quentin Tarantino’s Django Unchained after all. The actor was in negotiations to join Tarantino’s controversial western, which takes a harsh look at slavery in the 19th century as told through Tarantino’s oh-so-politically-correct pen, but now Variety’s Justin Kroll reports that the actor had to pass due to scheduling conflicts. Costner was poised to play the villainous role of Ace Woody, a man who trains male slaves to fight for the public’s amusement. Costner recently filmed his role as Clark Kent’s adoptive Earth father in Zack Snyder’s Man of Steel, and also has the History Channel miniseries The Hatfields and the McCoys and his directorial effort A Little War of Our Own on his plate so those projects may be to blame for the scheduling snafu.While I was quite looking forward to seeing Costner as a Tarantino-written baddie, Django Unchained is doing just fine casting wise. Jamie Foxx is set as the titular Django, a freed slave who sets out to rescue his wife, while Leonardo DiCaprio will play the film’s main villain, an evil plantation owner. Christoph Waltz, Gerald McRaney, and the recently confirmed Samuel L. Jackson also star. Django Unchained starts production this November in New Orleans and is slated for a December 25th, 2012 release.
