"Tropic Thunder" is a a comedy about five actors who go on location and find themselves relying on their boot camp experiences when they get stuck in a real war-like situation.

Jack Black will play Jeff "Fats" Portnoy, an overweight gross-out comedian, who's forced to kick his drug addiction while filming on location in the jungle. Robert Downey Jr. will play Kirk Lazarus, the greatest actor of his generation and a four-time Oscar winner. Jay Baruchel will play Kevin Sandusky, an unknown actor on the set and Stiller plays Speedman.

While it may surprise some that Ben Stiller is directing, I should mention that he has previously helmed "Zoolander" and one of my favorite comedies "Cable Guy." At this point, "Tropic Thunder" is scheduled to hit theaters on August 15th.
