Amitabh Bachchan has been part of Indian cinema for decades and has had his share of fascinating characters. As he mentions, the character he played as a doctor in 'Anand' was so powerful that each time he went to the script room, he got emotional because he knew that in that scene, as a doctor, he had to say something that would be very difficult. Then there was the intense role of a police officer in 'Zanjeer'. Some other notable performances include him playing God in various films. Here are some of those memorable roles.
