 Kamal Amrohi (qv) 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.
