Nanabhai Bhatt (12 June 1915 – 24 April 1999) was an Indian film director and producer who worked in Hindi and Gujarati cinema. He is known for making over a hundred fantasy and mythological films, including Mr. X (1957), Zimbo Comes to Town (1960), Lal Qila (1960) and the blockbuster Kangan (1959) starring Nirupa Roy and Ashok Kumar. His first film, Muqabala (1942), was the first to feature the double-role or "twins" phenomenon in Indian cinema, wherein lead actress Fearless Nadia alternated between the good sister and the gangster's moll. The formula was subsequently emulated in numerous Hindi films.
