Ready to enact the angry persona: BIG B

'I can still do it', says megastar Amitabh Bachchan on playing an 'angry young man' that pitch-forked him to stardom in the '70s. "With time you have to change. You don't have the same temperament that you had when you were in school or college. And I guess the roles that come your way are also like this. "That is not to say that it is lost. If there is anger to be depicted in a film, I can still do it. It depends on characterisation, what the director or the story demands from you," Bachchan told .The actor's last film 'Satyagraha' in which he played a man striving to bring change in the system and upcoming film 'Bhoothnath Returns' both have political undertones. But he says it was not intentional to do politically charged films back-to-back.
