The Shankar-Rajnikanth Tamil film Robot is now Enthiram. The film is said to be based on the popular writer, late Sujatha's novels En Iniya Iyanthira and Jeeno. 

Superstar Rajnikanth [Images] had earlier announced that the film, produced by London-based Aingaran Films International (P) Ltd., would get a Tamil title soon. The title wasn't intended to get tax-exemption but to honour the Government of Tamil Nadu's commitment to patronise films with Tamil titles. Produced at a whopping budget of Rs 140 crore, the film is said to be the most expensive film to have been ever made in India in any language. 

Three photo-shoots have been held to promote the film, including one that was shot in Hollywood last week. The shooting is expected to kick off in Brazil [Images] from September 6 onwards. 

Shankar's team is already in Brazil to oversee the arrangements. Shankar, Rajnikanth and other actors and crew members are expected to leave for Brazil on Friday while Aishwarya [Images] Rai-Bachchan, the heroine, is expected to land in Brazil on September 7.
