Tropic Thunder

I just found a couple early reviews of this movie. It's got Ben Stiller, Jack Black, and Robert Downey Jr., which is sort of a random assortment of actors, but they're all hilarious. They play smug big name actors shooting a war epic, and things go haywire and they have to try to be actual heroes.

Now I want to see a photo or trailer or something, because it sounds pretty good.
