“He had told me a plotline, the story idea that he had, which at that point I couldn’t do because I was about to leave for an outdoor (shoot) for a movie I did, 'Bol Bachchan'. Due to my unavailability, he went and made that film (with someone else). That film happened to be 'Kahaani', I didn’t know it was going to be 'Kahaani' and the role he was offering me turned out to be 'Bob Biswas'. I am not somebody who believes in regrets, you get what you deserve. You can’t live your life in regret and keep looking over your shoulder all the time,” Bachchan added.
