While shooting a blockbuster war film in the Vietnam wild, a cast of egocentric actors becomes engaged in a running battle with local drug lords. The performers think it’s all part of a show being filmed with secret cameras, which only further enrages the enemy. Despite an all- star cast of funnymen – led by Ben Stiller, Jack Black and a brilliant Robert Downey Jr – this high- concept, lowimpact farce doesn’t quite stir up a perfect storm of mirth. Never before has a seemingly throwaway comedy required so much heavy lifting from the viewer. Good enough, but it should have been great.
