Mumbai: DreamWorks Pictures is offering an original documentary Rain Of Madness starring Jay Baruchel, Jack Black, Steve Coogan, Robert Downey Jr., Bill Hader, Nick Nolte and Ben Stiller, a companion piece to the hit comedy Tropic Thunder, which debuted in theaters on 13 August, for download exclusively on the iTunes Store.

It was shot in Hawaii, at the same locations used in Tropic Thunder, along with the details and demise of the fictitious cast & crew as they struggle to finish shooting their film despite numerous shooting, budgeting and casting problems.

"We wanted to do a fake documentary about the making of the movie within the movie, which is called Tropic Thunder — not the actual movie Tropic Thunder. The fake documentary focuses on the real movie’s fake director, and what happens to the fake cast before they go into the real jungle. It’s pretty straightforward," said Stiller, one of the stars of the documentary and the director/star/producer and co-writer of Tropic Thunder.

"Original material for web consumption is a growing area for us, and Rain of Madness, dovetails perfectly with the theatrical release of Tropic Thunder. They complement and reinforce one another, while staying true to the comedic sensibility that Ben and his team brought to Tropic Thunder. We hope fans will appreciate this exclusive digital content and continue the experience at http://www.RainOfMadness.com," said Paramount Pictures senior vice president interactive marketing Amy Powell.
