After a stupendous response to the three parts of 'Bollywood Hungama Celebrates 70th Birthday', we are back with the fourth and last part of our special series on Mr Bachchan's 70th birthday. Many would call the last decade as the best phase of Amitabh Bachchan. He had won two national awards, has been doing a wide variety of roles, has stunned one and all with the phenomenal success of KBC and a superb show on the social networking sites like Twitter and Facebook and his Blog that he updates every day. This is one video you don't want to miss. Must watch!
