Starring Hrithik Roshan and the newcomer Pooja Hegde, the movie is set in the ancient city of Mohenjo-daro in the era of the Indus Valley civilisation.
Gowariker took over three years to develop the film.
"Mohenjo Daro is not just another historical; it's pretty much even before history begins. It's literally going back in the womb of time. It's a world that I am most fascinated with -- who were the people, how did they live, what was the society like, are some of the questions which always intrigued me. I am thankful that I got this opportunity to explore that world through cinema," Gowariker said in a statement.
Also starring Kabir Bedi and Arunoday Singh, "Mohenjo Daro" will release on August 12.
