When I first heard that Ben Stiller was making a movie-within-a-movie comedy about the Vietnam War, I wasn't too excited. Damn was I wrong, deadly wrong! Tropic Thunder is directed by Ben Stiller (Zoolander) and written by Etan Cohen ("King of the Hill", Idiocracy) and well-known actor Justin Theroux (who also stars in the film). The movie arrives in theaters everywhere on August 15th this summer.
