Talking about films, she said that not every movie can be a "Rang De Basanti" - the 2006 blockbuster helmed by Rakeysh Omprakash Mehra.
She said: "I have done a lot of powerful films, but I feel not every film will be 'Rang De Basanti'. It's not that all the films that I do is to give any message. 'Rang De Basanti' was the turning point in my career.
