Shree 420 is a 1955 Bollywood film directed, produced by and starring Raj Kapoor and Nargis. The number 420 refers to Section 420 of the Indian Penal Code, which prescribes the punishment for the offence of cheating; hence, "Mr. 420" is a derogatory term for a cheater. The film centers on Raj, a poor but educated orphan who comes to Bombay with dreams of success. Wikipedia
