Working in `Department` was unique experience: Big B

New Delhi: Megastar Amitabh Bachchan, who will next be seen in Ram Gopal Varma`s ‘Department’, says working in the film with advanced technologies was a unique experience.

"In `Department` its not just the 5D camera, several other advanced versions were also used... A unique experience!! Ram Gopal Varma has done just that in yet another pioneering effort in `Department`," Bachchan posted on Twitter.

The film also stars Sanjay Dutt and Rana Daggubati in prominent roles and will hit theatres on May 18.
