Saira Banu was born on 23 August 1944 in Bombay, Bombay Presidency, British India, now Mumbai, Maharashtra. She grew up in a family connected with the entertainment industry. Her mother was actress Naseem Banu, one of the prominent actresses of early Hindi cinema, while her father was film producer Mian Ehsan-ul-Haq.
Saira spent part of her childhood in London and later returned to India with the ambition of becoming an actress. She began her film career at a young age and made her Hindi-film debut with Junglee (1961) opposite Shammi Kapoor.
Junglee became a major success and established Saira Banu as a leading actress. Her performance and youthful screen presence made her one of the most popular new stars of the early 1960s. She received a Filmfare Award nomination for Best Actress for the film.
She followed her debut with successful films including Shagird (1967), Padosan (1968), Diwana (1967), Ayee Milan Ki Bela (1964) and April Fool (1964). Her comic performance in Padosan, opposite Sunil Dutt, remains one of her most memorable roles.
During the late 1960s and 1970s, Saira worked with many of Hindi cinema's leading actors, including Shammi Kapoor, Dev Anand, Manoj Kumar, Rajendra Kumar, Dharmendra and Dilip Kumar.
Some of her notable films from this period include Purab Aur Paschim (1970), Victoria No. 203 (1972), Sagina (1974), Hera Pheri (1976) and Bairaag (1976). Her performances demonstrated her ability to move between romantic dramas, comedy and social films.
Saira Banu married legendary actor Dilip Kumar on 11 October 1966. Their marriage became one of the most well-known partnerships in Indian cinema. They remained together until Dilip Kumar's death in 2021.
Saira gradually reduced her acting work during the 1970s and made fewer film appearances later in her career. Her final major film appearances included Faisla (1988), although she had largely withdrawn from regular acting by that period.
In addition to her film career, Saira Banu has remained an important figure in discussions about the history of Hindi cinema and the legacy of Dilip Kumar. She has continued to share memories and stories about their life and work.
