Aamir Khan is slated to begin shooting with Amitabh Bachchan for Vijay Krishna Acharya's 'Thugs Of Hindostan' next month. Known as Mr Perfectionist, Aamir has reportedly said that he is not competing with the Big B. He feels they have to do what is required of their roles, to the best of their abilities. "The better the actor around me will do, the better I will do," Aamir quipped.
