Murli Prasad Sharma (Munna Bhai) is portrayed by Sanjay Dutt. He is a "Bhai" - a leader in the Mumbai underworld. His nickname, Munna Bhai has a double meaning. It could refer to the form of "Bhai" as an honorific, as the word traditionally translates as "brother"; however, within the context of Mumbai slang, "Bhai" has also come to refer to a hoodlum. His sidekick, or consigliere is Circuit (portrayed by Arshad Warsi). They both speak in Bambaiya Hindi, a dialect specific to Mumbai, India.
