Enthiran is a forthcoming science-fiction Tamil–language film being directed by S. Shankar, who with Enthiran, directs his tenth feature film. Despite several rumours regarding the lead actors, Rajinikanth and Aishwarya Rai have been formally announced to portray the lead roles. The film is expected to cost 120 crores, one of the highest ever film budgets of the Chennai film industry.
Initially titled and referred to as Robot, the project was launched by Shankar and producer C. Karunamoorthy, chief executive of Ayngaran International who were set to distribute the film along with Eros Labs. However, in December 2008, both production companies backed off, amidst filming schedules, due to financial problems led by the currently ongoing global market recession. Production rights have now been sold to the Chennai-based Sun Pictures.
