Tropic Thunder is a 2008 satirical action comedy film directed by Ben Stiller. It stars Stiller, Jack Black, Robert Downey Jr. , Jay Baruchel, and Brandon T. Jackson as a group of prima donna actors who are making a Vietnam War film. When their frustrated director (played by Steve Coogan) drops them in the middle of a jungle, they are forced to rely on their acting skills to survive the real action and danger. The screenplay by Justin Theroux, Stiller, and Etan Cohen was from a story by Stiller and Theroux. The film was produced by Stuart Cornfeld, Stiller, and Eric McLeod for Red Hour Productions and DreamWorks Pictures as an international co-production between the United States, Germany and the United Kingdom.
