In this latest season of Project Greenlight, which debuted last weekend on HBO, Matt Damon made a comment to one of the other judges (an African-American) about diversity. It did not go over well. I must admit, it made me a little uncomfortable when I saw it initially. It's not so much what he said--it was more the tone he used when he said it--and who he said it to.
The Washington Post has the whole story if you're interested.
