While Samuel L. Jackson’s role in the upcoming superhero epic The Avengers certainly won’t hurt his status as “highest grossing actor ever,” that doesn’t mean the veteran will neglect his acting roots. Jackson once again teams with director Quentin Tarantino for Django Unchained later this year, a movie which draws inspiration from some of the ugliest events in American history. While we’ve brought you some good looking images of Christoph Waltz in character and of the first teaser poster, the plot itself is a bit on the ugly side. It revolves around Django, a freed slave (Jamie Foxx) and Dr. King Schultz, a German-born bounty hunter (Waltz) who are out to rescue Django’s wife, Broomhilda (Kerry Washington). Jackson plays a “house slave” of plantation owner, Calvin Candie (Leonardo DiCaprio). The outstanding cast also includes Kurt Russell, Garrett Dillahunt, Walton Goggins, RZA, M.C. Gainey, Dennis Christopher, Gerald McRaney, Laura Cayouette, Don Johnson, Tom Savini, and Sacha Baron Cohen. Django Unchained opens December 25th. Hit the jump to see what Jackson had to say about how Tarantino aims to handle the sensitive subject matter.
