Sunil Dutt and Zeenat Aman's only movie.
Director OP Ralhan offered Phool Aur Patthar (1966) to Sunil Dutt but he declined and Dharmendra did that film. Like Phool Aur Pathar, this film was also successful.
Bappi Lahiri sampled Led Zepplin "Immigrant Song" for the song "Pyar Gunaah Hain".
Padma Khanna replaced Helen in the film.
Raaj Kumar was offered the film but refused.
