After the shooting for Vidhu Vinod Chopra's film 'Eklavya', model-turned-actor Vidya Balan is back in Mumbai. Though she doesn't have a big role in it. About the character she says, "I have a significant but small role compared to my debut film. But it didn't stop me from doing it, as working with Vinod Chopra's unit was always like a holiday, and to top it all, I was getting a chance to work with the biggest superstar from the industry, Amitabh Bachchan."
