Nawazuddin Siddiqui has already started with the promotions of his next, ‘Babumoshai Bandookbaaz’ even as his ‘Mom’ is still running successfully. At the new film’s trailer launch, the actor revealed why he will never play a hero or a villain on the silver screen, “I don’t like to play an extreme villain or an out-and-out hero. Everyone has positives and negatives, such realistic roles interest me. We can never find anyone like our heroes in real life. I don’t like to play such non-existent characters. Times have changed, our heroes now like to play characters which have a grey shade to it. I also enjoy doing such stuff.” ‘Babumoshai Bandookbaaz’ will see Nawaz playing a rustic sharp shooter.
