On the right we have a clearly recognizable Ben Stiller. On the left we have a somewhat less recognizable Jack Black. And in the middle, Robert Downey Jr. in blackface.
Hoo boy.
Teaser site here. Apparently this is a comedy about the filming of a Vietnam war epic, during which the cast accidentally wanders into a real war zone. Stiller directs as well as stars. Oh, and Downey's character is a white actor playing a part originally written for a black man, and he's so method he gets plastic surgery and dyes his skin rather than have the character adjusted.
