The film was in the making for 8 years. Financial reasons caused the film to get shelved for a while. Nargis also got pregnant with two of her daughters during the making of the films. Newcomer Feroz Khan was signed for the film in 1962. After years of struggle, Nargis decided to complete the film and have it released.
There were several stories in the media that Pradeep Kumar harassed Nargis's brothers during the making of the film. Pradeep would cancel shootings and always report late. He also demanded more money. Pradeep stated this was false. Pradeep stated that everything promised to him was conveniently forgotten. The producers promised Pradeep Kumar they would go to Russia and get a special mask made . This was part of the scripts requirement. But it never happened. Pradeep Kumar stated he never held up the shooting despite being a top star. He only completed the film due to his friendship with Sunil Dutt and Nargis.
