"No one needs to question what I have done for Mumbai, for I know what I have done," Bachchan said.

He was reacting to a question on an article in the Sena mouthpiece Saamna that compared him with Tamil superstar Rajnikanth, who is agitating for Tamil Nadu on the issue of Hogenakkal water project.

The article: 'Rajnikanth Khalya Meethala Jaagla' (Rajnikant has been loyal) said though he was born in Maharashtra and grew up in Karnataka, he took sides with Maharashtra after achieving superstardom.

The article said, ‘several actors who live in Mumbai achieve fame and glory. But when it comes to taking a firm stand on the issue of Marathi or regional pride many of film stars including Amitabh Bachchan backtrack'.
