Moviefone HQ is officially running out of 'Django Unchained' ledes. Seriously, Quentin Tarantino, the cast of your next movie is already stacked -- how many roles are in this thing? Perhaps an infinite amount. According to Deadline, Michael Kenneth Williams (Chalky White from 'Boardwalk Empire' and Omar from 'The Wire') is in talks to potentially play hired muscle for ranch owner Calvin Candle (Leonardo DiCaprio) in the new film. Williams was originally considered for the part of Django, but it ended up going to Jamie Foxx.
