Movie Plot
The men star as a trio of actors whose filming experience in southeast Asia gets a little too real and the actors must become as tough and clever as the characters they play to get out of a crisis.
John Portnoy played by Jack Black - battles a Heroin addiction and makes this film an absolute treat to watch. Funny from start to end!
