The film is set in Mississippi during slavery which tells the story of slave Django, who's liberated by a German dentist-turned-bounty hunter (Waltz) and taught the tricks of the trade by his mentor.
However, his main goal in life is to recover his wife but needs to get past the villainous ranch owner Calvin Candie (DiCaprio), who runs club Candyland, where his spouse and other female slaves are exploited as sex objects and males are pitted against each other in death matches.
Jackson is to play the role of Stephen, Candie's valet who keeps the slaves in line at Candie's residence.
Filming is expected to start later this year.
