In the action-comedy Tropic Thunder, 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.

Tropic Thunder opens on August 15.

Mike Myers is an American who was left at the gates of an ashram in India as a child and raised by gurus. He moves back to the U.S. to seek fame and fortune in the world of self-help and spirituality.

The Love Guru will be released on June 20.
