The forthcoming Rajnikant starrer and Shankar directed Robot has been renamed as 'Enthiram'.

However, Shankar has retained the original title as the sub-title. The movie, following the style of ' Sivaji : The Boss', has been rechristened as 'Enthiram: the Robot'.

The film, which is arguably the first full-fledged sci-fi film in Tamil, is said to be based on two novels written by late Sujatha.

Rajnikant had earlier announced that the film, produced by London-based Aingaran Films International (P) Ltd., would get a Tamil title soon. The Tamil title was not intended to get the tax-exemption, but to honour the State Government's commitment to patronize films with Tamil titles.

‘Eyanthira’ and ‘Eyanthiran’ were earlier considered and the final choice fell on the title 'Enthiram – The Robot'.

Three photo-shoots have been held to promote the film, including one that was shot in Hollywood in U.S. last week. The shooting of the film that also stars Aishwarya Rai Bachchan, is expected to kick off in Brazil from today.

Produced at a whopping budget of Rs.140 crores, the film is said to be the most expensive film made in India in any language till date.
