"Tropic Thunder" starts off with three hysterical trailers for fake movies starring the three main actors in the film. Ben Stiller is Tugg Speedman who has made a living as an action superstar. His latest film is "Scorcher VI: Global Meltdown"...and the trailer perfectly apes idiotic disaster films.

Jack Black plays a comedian who has donned a fat suit to play multiple members of an overweight family called "the Fatties". And Robert Downey Jr. as the serious Oscar winner of the bunch is appearing in a homo erotic monk love story. There are also commercials for fake products.....all of which are a perfect build-up to the film itself which doesn't disappoint. It may not be politically correct but for me, it's the funniest film of the year.
