play and took permission from her father to cast her as a heroine in his Bengali film Roshanara (1952), her cinematic debut. After acting in a couple of films in Calcutta, Mala Sinha went to Bombay for a Bengali film. There she met Geeta Bali, a noted Bollywood actress, who was charmed by her and introduced her to director Kidar Sharma. Sharma cast her as a heroine in his Rangeen Ratein. Her first Hindi film was Badshah opposite Pradeep Kumar, then came Ekadashi, a mythological film opposite Trilok Kapoor. Both films did not do well, but her lead role in Kishore Sahu's Hamlet, paired opposite Pradeep Kumar, fetched her rave reviews in spite of it failing at the box office. Films such as Lai Batti (actor Balraj Sahni's only directorial venture), Nausherwan-E-Adil where she starred as the fair maiden Marcia in Sohrab Modi's romance about forbidden love and Phir Subah Hogi, which was director Ramesh Saigal's adaptation of Dosteovsky's Crime and Punishment established Mala Sinha's reputation as a versatile actress who took the maximum career risks by accepting unconventional roles. She used to sing for All India Radio; she was not allowed to sing playback (even for herself) in the movies with the lone exception being 1972's Lalkar. In the 1950s, she had string of hits opposite Pradeep Kumar such as Fashion (1957), Detective (1958) and Duniya Na Mane (1959). The films she did with Pradeep Kumar were men-oriented. In 1957, noted Bollywood actor and director Guru Dutt cast Mala Sinha in his film Pyaasa (1957) in a role originally intended for Madhubala. Mala Sinha performed in the relatively unsympathetic part of an ambitious woman who chooses to marry a rich man (played by actor Rehman) and have a loveless marriage, rather than a poor, unsuccessful poet; her impoverished lover (played by Guru Dutt) whom she ditches. Pyaasa remains to this day a classic in the history of Indian cinema and a turning point for Sinha. After Pyaasa, her major successes were Phir Subah Hogi (1958) and Yash Chopra's directorial debut Dhool Ka Phool, (1959) that elevated her into a major dramatic star. She was part of many successful movies from 1958 to the early '60s such as Parvarish (1958), Ujala, Main Nashe Main Hoon, Duniya Na Mane, Love Marriage (1959), Bewaqoof (1960), Maya (1961), Hariyali Aur Rasta, Dil Tera Deewana (1962), Anpadh and Bombay Ka Chor (1962). She consistently
