Sunil Dutt

Director Ramesh Saigal was instrumental in giving Dutt a break in the film Railway Platform (1955) when the latter was hosting the show, Lipton Ki Mehfil on Radio Ceylon.[13] While covering the Dilip Kumar film Shikast in 1953, Dutt met director Saigal, who impressed by his personality and voice, offered him a role in his upcoming film. Saigal came up with the new screen name "Sunil Dutt" for the debutante actor whose real name was Balraj Dutt to avoid name conflicts with the then veteran actor Balraj Sahni.[14][15]

Dutt in 1958

Dutt shot to stardom in the 1957 film Mother India in which he co-starred with Nargis as her short-tempered, angry son. During the making of this film, a fire happened on the set. It is believed that Dutt braved the raging fire to save Nargis and thereby won her love. They went on to marry in 1958. They had one son Sanjay Dutt, also a successful film actor, and two daughters, Priya Dutt and Namrata Dutt. His daughter Namrata married Kumar Gaurav, son of Rajendra Kumar. The two fathers were co-stars in Mother India.

Dutt was one of the major stars of Hindi cinema in the late 1950s and 1960s and continued to star in many successful films which included Sadhna (1958), Insan Jaag Utha (1959), Sujata (1959), Mujhe Jeene Do (1963), Khandan (1965), Mera Saaya (1966) and Padosan (1967). His collaboration with B.R. Chopra proved to be successful in films such as Gumraah (1963), Waqt (1965) and Hamraaz (1967). One of his favourite writers and friends was Aghajani Kashmeri. Dutt made his directorial debut and was the only actor to feature in the 1964 film Yaadein. The film was featured in the Guinness Book of Records for Fewest Actors in a Narrative Film. He later produced the 1968 film Man Ka Meet which introduced his brother Som Dutt, Vinod Khanna and Leena Chandavarkar. In 1971, he produced, directed and starred in Reshma Aur Shera (1971) which was critically well received but a box office failure.

During the early 1970s, his career as an actor was at a stand-still. Amidst this setback, he played Madhubala's hero in the 1971 film Jwala, which was a delayed film that had started production in the late 1950s and was Madhubala's last film. It was Geeta Mera Naam (1974) that brought him into the limelight again. The anti-hero was reborn after a long gap of films like Mother India and Mujhe Jeene Do. Sunil Dutt's performance of Johnny was liked by the masses as he clearly stole the limelight. It was one of the best performances of his career. He continued to star in hits that included Heera (1973), Pran Jaye Par Vachan Na Jaye (1974), Nagin (1976), Jaani Dushman (1979), Muqabla (1979), and Shaan (1980). He also starred in a series of Punjabi religious movies in the 1970s: Man Jeete Jag Jeet (1973), Dukh Bhanjan Tera Naam (1974), and Sat Sri Akal (1977).[16] Even in 1980s he starred in both leading and supporting role in several successful movies such as Dard Ka Rishta (1982), Badle Ki Aag (1982), Raaj Tilak (1984), Mangal Dada (1986), Watan Ke Rakhwale (1987) and Dharamyudh (1988).

He launched his son Sanjay's career with Rocky in 1981 which was a success. Shortly before the film's release, Nargis died of pancreatic cancer. He founded the Nargis Dutt Foundation in her memory for the curing of cancer patients.[17] He was a sponsor of the India Project, an organisation akin to Operation Smile for the treatment of Indian children with facial deformities.[18]

In 1982, he was appointed as the Sheriff of Bombay, an apolitical titular position bestowed on him by the Maharashtra government for a year.[19]

He retired from the film industry in the early 1990s to turn to politics after his last few releases including Yash Chopra's Parampara (1993) and J.P. Dutta's Kshatriya (1993).

In 1995, he won the Filmfare Lifetime Achievement Award for his contribution to the film industry for four decades. He returned to acting shortly before his death in 2003's Munna Bhai M.B.B.S. in which he shared the screen with his son Sanjay for the first time although they had appeared earlier in Rocky and Kshatriya but did not share any scenes together.

His closest friends from the film industry included Dilip Kumar, Dev Anand, Rajendra Kumar, Kishore Kumar, Lata Mangeshkar, Yash Chopra, Waheeda Rehman and Sanjeev Kumar.
