Bollywood star Hrithik Roshan has decided to undertake detailed research on the Indus Valley Civilization, for his upcoming film, Mohenjo Daro, reported Hindustan Times.

Mohenjo Daro, meaning Mound of the Dead in Sindhi, is a lost civilization that was abandoned in 19th century BCE. The city’s ruins lie in the Larkana district of Sindh, and are a designated Unesco World Heritage Site since 1980.

Hrithik, who isn’t very familiar with the subject, has decided to meet archaeologists to learn about the civilization.

"Hrithik has decided to meet archaeologists to learn about the civilization in more detail. He wants to know more about the people, their behaviour and some striking features about them that would help him portray his character authentically," said a source close to the actor.

The star is currently busy promoting his next film, Bang Bang, and plans to begin his research once the film releases early next month.

"He is planning to do proper research of his own for a month once his next film releases," confirmed Hrithik's spokesman.

Directed by Gowariker, the film stars Hrithik and new comer Pooja Hegde in an epic adventure love story set at the time of the Indus Valley Civilization.

Given the settings, the movie is likely to be a sweeping historical extravaganza, along the lines of Jodhaa Akbar and Lagaan.

Mohenjo Daro is set to go into production in South Africa from October 2014.
