Amitabh is alcoholic and an egoistic person in Shamitabh

Bollywood megastar Amitabh Bachchan may have been in the film industry for four decades now but he feels the stardom of an actor is transitory as a new superstar is born in every 5 to 10 years. Amitabh says the story of 'Shamitabh' revolves around the ego clash between two characters but Amitabh Bachchan says it bears no similarity with his 1973 hit 'Abhimaan'.The trailer of 'Shamitabh' shows the actor in a drunk state. Bachchan who has played similar roles in 'Sharabi', 'Do Anjaane', 'Amar Akbar Anthony' and 'Hum' among many others, said he delivers such scenes without touching the alcohol.
