Mumtaz started her career by playing many junior artist roles. She should be considered as the luckiest of the lot because none of the junior artistes so far have been able to graduate into a top heroine. Her stars were good to her and so were her pin-up good looks. She was courageous also because she worked with the likes of Mehmood and Dara Singh. In the case of the latter, there were at least a dozen films like 'Sikander-e-Azam' and 'Khakaan'. Some of her movies with Mehmood were 'Do Dil' and 'Bedaag'. Soon Mumtaz was discovered by the top film makers and her future shone brightly for her. Some of her major movies were 'Ram Aur Shyam' with Dilip Kumar (1967), 'Do Raaste', (1969) 'Sacha Jhoota' (1970) with Rajesh Khanna, 'Khilona' (1970) with Sanjeev Kumar and 'Aap Ki Kasam' (1974) with Rajesh Khanna and Sanjeev Kumar. Many of her ways, like the way she dressed and carried herself, were imitated by all the eve-populace of India. She retired from the industry after she tied the knot but after 16 years tried to make a comeback. Her comeback film 'Aandhiyan' with Shatrughan Sinha was badly accepted by the audiences. She had changed completely. This forced her to retreat her steps from the world of glamour and expectations.
