Anwar Hussain is the head of thugs with Helen being his lead lady.
The bhangra song of the movie by Kishore Kumar and Lata Mangeshkar, became very popular.
In the movie, Mohammed Rafi and Asha Bhosle have sung a Qawwali for Ashok Kumar and Padma Khanna (in a guest appearance), which was a gem.
Some part of the Qawwali and lyrics were used by R. D. Burman in the film Hum Kisise Kum Naheen for the song "Hai Agar Dushman".
