Besides Kala Bazar, Rehman acted in 3 other films in 1960, which were Ek Phool Char Kaante, Girlfriend and Chaudhvin Ka Chand. The lattermost was another partnership between Rehman and Dutt, and was the fourth-highest grossing Hindi film of 1960. It was considered a "saving" point in Dutt's career, after their last collaboration, Kaagaz Ke Phool (1959) received an underwhelming response at the box office, which now is considered a classic. It also represented the strained relationship of the duo. Dutt's existing marriage and her film successes with other directors caused them to drift apart both personally and professionally, although they continued to work together into the 1960s. Their last film together was the drama Sahib Bibi Aur Ghulam (1962), starring Dutt, Meena Kumari, Rehman and Rehman herself in a supporting role, and the movie was a huge success and was lauded by Indian and international critics. The film earned Rehman her first Filmfare nomination in the category of Best Supporting Actress, and the film itself received nominations for the Golden Bear at the 13th Berlin International Film Festival and was selected as India's official entry to the Oscars, in addition to a Filmfare Award for Best Film. Rehman and Dutt finally broke away in 1963, and a year later, Dutt was found dead on 10 October 1964 in Mumbai, reportedly from an overdose mixture of sleeping pills and alcohol.
