Mira Nair is trying to do something that no filmmaker in Bollywood has managed so far. Vidhu Vinod Chopra could not convince Amitabh Bachchan to grow a real beard for Eklavya and hence a false one was used. But Mira Nair might just convince the superstar to go bald for her movie Shantaram. While Hollywood star Johnny Depp will play the lead role, Amitabh Bachchan has already been signed to play the role of underworld don Kader Bhai.
