After writing dialogues and screenplay for films such as Aashirwad, Anand and Khamoshi, Gulzar directed his first film Mere Apne (1971). The film was a remake of Tapan Sinha's Bengali film Apanjan (1969). Meena Kumari played the lead role of Anandi Devi, an old widow caught in between the local fights of unemployed and tormented youngsters. Anandi Devi's death in one of the fights makes them realise the futility of violence. The film was rated "Above Average" at the box office. He then directed Parichay and Koshish. Parichay was based on a Bengali novel, Rangeen Uttarain by Raj Kumar Maitra and inspired from the Hollywood film The Sound of Music. He wrote the story of Koshish based on the struggle faced by a deaf-dumb couple wherein Sanjeev Kumar won National Film Award for Best Actor. In 1973, he directed Achanak, inspired by the 1958 murder case KM Nanavati v State of Maharashtra, and the story writer Khwaja Ahmad Abbas earned a Filmfare nomination for Best Story. Later he directed Aandhi, based on the Hindi novel "Kaali Aandhi" by Kamleshwar. Along with various wins and nominations, the film also won Filmfare Critics Award for Best Movie. Although the film was believed to be based on the life of former Indian Prime Minister Indira Gandhi, the film was based on life of Tarkeshwari Sinha. In the 1975's emergency, the film was banned from theatres. His next film Khushboo was based on Sharat Chandra Chattopadhyay's Pandit Mashay. His Mausam, which won the National Award for 2nd Best Feature Film, Filmfare Best Movie and Filmfare Best Director awards, along with other six Filmfare nominations, was loosely based on the story "Weather", from the novel, The Judas Tree, by A.J. Cronin. His 1982 film Angoor was based on Shakespeare's play The Comedy of Errors.
