Director Shankar known to be a perfectionist when it comes to finalizing locations with the grandeur element is reportedly on a three-week world tour to choose the right locations for his film 'Robot' starring superstar Rajinikanth.
Shankar has planned on beautiful Vienna in Austria for a spectacular song sequence. The ace director accompanied by cinematographer Ratnavel, will be going to Austria first and then will scout for locations in Rio de Janeiro, the second major city of Brazil.
Starting off a film by shooting a spectacular song sequence has been Shankar's habit over the years. The 'Vaaji, Vaaji' song was shot in Hyderabad in an extravagant set before proceeding with the rest of the 'Sivaji'. Similarly, 'O Sukumari' was picturized first for 'Anniyan'. Going by the same trend, one can expect 'Robot' to be kick started with a song sequence featuring Rajinikanth and Aishwarya Rai in Vienna.
Hanoi in Vietnam would be the duo's final destination in their location hunting spree.
The shooting for the film is expected to begin sometime in August.
