Robert Downey Jr. is seen here between actors Jack Black, left, and Ben Stiller, in an image from new film Tropic Thunder in which he wore a wig and make-up to look like a black man. What, Don Cheadle wasn't available? I'm sorry, I don't get it.
Clearing anticipating a backlash, Downey Jr told a US magazine: "If it's done right, it could be the type of role you called Peter Sellers to do 35 years ago. If you don't do it right, we're going to hell."
The movie is about a group of arrogant actors making the most expensive Vietnam war movie ever made.
