The four-time National Film Award winning actor has been studying Bush's speech, gait and mannerisms with the help of compact discs and computer graphics for two weeks.
And that is not all - he will play nine more roles in the same film. Make-up artists from the US and Britain are helping him to get the right look for the roles.
A replica of the White House was erected here to bring the authentic look during the shooting and the total cost of the set is estimated to be Rs.5 million.
The film is being made on a mega budget of Rs.500 million. K.S. Ravikumar directs "Dasavataram", which is a production of Oscar Films. It is scheduled for a Diwali release.
