For those who didn't know, the role of Django in "Django Unchained" was actually offered to Will Smith prior to Jamie Foxx taking the lead.  Smith, however, turned down the chance to be a part of the blockbuster, Oscar winning hit, and explained exactly why he didn't accept the role to Entertainment Weekly.

"Django wasn't the lead, so it was like, I need to be the lead. The other character was the lead! I was like, 'No, Quentin, please, I need to kill the bad guy!'"

In the end, the film turned out to be a masterpiece regardless.
