It's funny you mention that, Elle. I just went and saw that movie today (not knowing a thing about Pierre being involved, as I haven't been checking in on IMDb lately). And there, in the very beginning of the credits, was his name. I went "Woohoo, Pierre!" The people around me looked at me strangely. Oh, well.
Good movie, by the way. Not great - flawed - but good. Ultimately I think it's about how journalism has come to mean telling the people what (it's thought) they want to hear, instead of telling them the truth. Good stuff. And definitely the first movie I've truly enjoyed Josh Hartnett in. I finally saw the light in his eyes - many times.
