This was the first film raj kapoor made without nargis as heroine. Raj kapoor wanted to know that could he make a film without nargis. After this film Raj kapoor knew that he can. Pran benefited from this film because of the role and his perfomance. This was the last RK film in b/w. During the shooting of this film, Raj Kapoor got the idea of ram teri ganga maili, which he made after 20 years.
The director was Raj Kapoor's long-time cameraman. However, significantly perhaps, it is Kapoor's name (as the producer) that is the first and last to appear on screen.
The wide-screen DVD has chopped several credits from the bottom of the screen. The ones that are missing are: Salochana Chatterjee, Harish, A. Mulla, Y.R. Virkud and Ansari. Only the tops of the letters of some other names are visible.
When Raj Kapoor narrated the script to shankar-jaikishan, his music composers. They were not happy. They said that this film is based on dacoir, so there's no scope for them. Those days it'svery unusual to have songs in such movies. Raj Kapoor was so sure about his own talent that he asked them to make music/ songs and he will find the situations for the song without damaging the storyline.
The heading on the page of the credits listing assistants has a typographical error. Instead of "assistants" it says "assisianis".
