 During the making of the film, composer Ghulam Mohammed (qv) and  cinematographer Josef Wirsching (qv) died, leaving director  Kamal Amrohi (qv) at a loss. Eventually, though, composer  Naushad (I) (qv) was brought in to compose the background score;  and after Wirschings death, over a dozen of Bombays top  cinematographers stepped in as/when they had a break from their  other assignments, and they maintained an even look.
