In about a week, "Tropic Thunder" will be screened in numerous theaters across the country. Hypening up fans' excitement about the Ben Stiller's comedy, DreamWorks Pictures have unleashed a batch of new videos related to the upcoming film. Two out of six new videos, a clip and a behind-the-scene featurette are taken from the movie, while the rest are made in the format of its mockumentary "Rain of Madness".

Telling the story of a group of actors involved in a real war-like situation while filming a Vietnam War movie, "Tropic Thunder" focuses on five completely different actors, pampered action star Tugg Speedman, overweight gross-out comedian Jeff 'Fats' Portnoy, multiple Academy Award-winner Kirk Lazarus, African-American actor Alpa Chino and unknown actor Kevin Sandusky. Dumped by their fed up director in the middle of a jungle, they soon realize that they have to fight for their life when they accidentally cross the territory of a heroine cartel.

Starring Stiller, Jack Black, Robert Downey Jr., Brandon Jackson, Jay Baruchel among others, the movie co-written by Stiller, Justin Theroux and Etan Cohen is coming out on August 13.
