It took 14 years for this film to be completed. To begin with, the film was launched in 1958, jointly planned by Kamal Amrohi and 'Meena Kumari'. It was launched in black-and-white, but when colour came in vogue, Amrohi scrapped those portions already shot and decided to start again. Later, Cinemascope came into vogue, and Amrohi acquired a Cinemascope lens from MGM and scrapped the plain colour portions too. Then Amrohi and Kumari separated in 1964, bringing filming to an indefinite halt. Finally, the film was resumed in 1968, and though by then Kumari was suffering from alcoholism and was in critical condition, she was still Amrohi's only choice and she agreed to complete the film.
Kamal Amrohi acquired a Cinemascope lens from MGM on a royalty basis for shooting the film. However, he detected a focusing error in the rush prints that had been missed by the cameraman and even the UK lab team that processed the film. On hearing of this, MGM instructed its Indian subsidiary chief not to collect any more royalty and gave the lens to Amrohi as a gift.
In 1972, veteran actor Pran Sikand turned down his Filmfare Award for Be-Imaan (1972), because while the Filmfare Best Music Award had gone to Shankar-Jaikishen for his own film Be-Imaan (1972), he felt that Pakeezah (1972) had not been awarded on merit and that the late 'Ghulam Mohammed' was more deserving of that award.
Kamal Amrohi was told that he and his crew would receive a special award for this film - for a consideration. He flatly refused to "buy an award."
During the making of the film, composer 'Ghulam Mohammed' and cinematographer Josef Wirsching died, leaving director Kamal Amrohi at a loss. Eventually, though, composer Naushad was brought in to compose the background score; and after Wirsching's death, over a dozen of Bombay's top cinematographers stepped in as/when they had a break from their other assignments, and they maintained an even look.
