Lots of actors circled the title role for Quentin Tarantino's DJANGO UNCHAINED - Will Smith, Idris Elba - but one actor has apparently signed on the line that is dotted - Jamie Foxx, who will join Leonardo DiCaprio, Samuel L. Jackson, and Christoph Waltz in Tarantino's "Southern", his slave drama film, to be released in 2012,
Foxx is no stranger to dramatic roles, having won the Oscar for RAY, and I think he's a good choice. My personal favorite was Elba, but Foxx is no slouch and will work well with the cast. I just want to see this thing - I haven't read the script. I read INGLOURIOUS BASTERDS and regretted it - it was such a rich script that I wish I'd held out and experienced it first on the big screen. Won't be making that mistake this time. DJANGO UNCHAINED is being produced by the Weinstein Company
