Amitabh Bachchan is one man, who is an example when it comes to friendship and help. This time it was Anupam Kher, who was helped by Big B. Apparently, Anupam is playing the lead role in Karan Razdan's new movie 'Mr Bhatti ki Chutti' and his role is that of a crazy fan of Big B. One of the scene required Anupam to interact with the watchman at Big B's residence boasting about his friendship and Karan wanted the watchman to be the real one, but was hesitant to talk to Bachchan. Anupam did the honors and Amitabh, the gentleman that he is, readily obliged.
