Shankar has proved that a director is indeed the captain of a ship. The director is having sleepless nights to finish his much-hyped flick Endhiran by the end of this year, starring superstar Rajnikanth and Asihwarya Rai Bachchan.

The process of shooting becomes much harder for the director, since its being shot in hectic locations. But the director is making sure that nothing goes wrong with the film and the film turns out to be master piece.

Shankar's problems have been eased a bit with Aishwarya picking up Tamil language very quickly. Even Rajnikanth is said to be impressed as he had never seen anyone from North India speak in Tamil so well.
