Tropic Thunder, hitting theaters August 15, stars Ben Stiller, Jack Black, Robert Downey Jr., Nick Nolte, Brandon Jackson, Steve Coogan, Danny McBride, Bill Hader, Jay Baruchel, Matt Levin, Andrea De Oliveira and Reggie Lee.
Ben Stiller plays pampered action superstar Tugg Speedman, who is cast in the biggest, most expensive war movie ever produced. He sets out to Southeast Asia with a "Who's Who" of celebrity co-stars. They include Kirk Lazarus (Robert Downey Jr.), an intense, three-time Oscar-winning actor; Jeff Portnoy (Jack Black), star of the popular gross-out comedy franchise "The Fatties"; multi-platinum hiphop-star-turned-entrepreneur-turned-actor Alpa Chino (Brandon T. Jackson); and first-timer Kevin Sandusky (Jay Baruchel). Soon after the production begins the actors are thrown into a real-life situation and are forced to become the fighting unit they're portraying, in order to find a way out of the jungle in one piece.
