Saira Banu in an interview once said" I was all in love with Dilip Kumar right from the age of 12 after watching 'Aan' I was not just another girl smitten by Dilip Kumar. For me, it was no castle in the air because I had given my dream the strong foundation of faith- faith in myself and faith in God.”
She was only 16, had gone for the show, hoping to get a glimpse of her favorite hero in person. But she was heartbroken as Dilip Kumar was unable to come to the premiere. She still remembers her first encounter with Dilip Kumar “When he smiled at me and remarked that I was a pretty girl, I could feel my whole being taking wing and flying rapturously. I knew somewhere deep within me that I was going to be his wife.”
After the release of Junglee, her first film in 1961, she became a big star, she was offered heroine roles with all the big stars of that time. Dilip Kumar in his biography told that a few films were offered to him with Saira but he refused because he felt to be her too young as his heroine.
It is said that it was Naseem Banu, her mother played the role of the cupid between Dilip and Saira. She got them closer, thanks to which love blossomed between the two. Dilip Kumar mentioned in his biography that when he fell in love with Saira. It was during a party thrown to celebrate her birthday. The actor revealed, "When I alighted from my car and entered the beautiful garden that leads to the house, I can still recall my eyes falling on Saira standing in the foyer of her new house looking breathtakingly beautiful in a brocade sari. I was taken aback because she was no longer the young girl She had indeed grown to full womanhood and was, in reality, more beautiful than I thought she was.
It was one day when Saira Banu was shooting for the film'Jhuk Gaya Aasman' Dilip Kumar proposed Saira. He simply stepped forward and shook her hand and proposed. Dilip Saab said, "Saira, you are not the kind of girl I want to drive around with or be seen around with... I would like to marry you... Will you be my wife?" Promptly came the response from Saira, "And how many girls have you said this to?" She, however, said yes.
They married on 12th Oct 1966 and celebrated the Golden Jubilee of their marriage in 2016. She remained her pillar of strength throughout all these years. There was a time when Dilip Kumar married another lady but Saira continued to look after him. The second marriage lasted for two years since then the two have stood beside each other like a rock, considering one another to be the greatest gift of God.
Saira Banu continued to work in films after the marriage, in fact, Dilip Kumar encouraged her to do films but she restrained herself to one or two films a year. Aman (1967), opposite Rajendra Kumar, was her first release after marriage to the thespian. She acted in three films with Manoj Kumar, Shaadi, Purab Aur Paschim, and Balidan. Cult film Padosan, in 1968, opposite Sunil Dutt, catapulted her to the top league and she continued to play the heroine for several years after that. Victoria No. 203 with Navin Nischol is her biggest hit. She acted in three films with her husband: Gopi. Sagina and Bairaag. Only Gopi was successful at the box office. She acted in three films with Manoj Kumar, Shaadi, Purab Aur Paschim, and Balidan and six with Dharmendra: Jwar Bhata, Aadmi Aur Insaan, Resham Ki Dori, Pocket Maar, International Crook and Chaitali.
She worked with Amitabh Bachchan in Amitabh Bachchan in Zameer and Hera Pheri. Nehle Pe Dehla. She never worked with Rajesh Khanna though once she was offered the role in Chhoti Bahu in 1971 but couldn't do it due to illness.
Dilip Kumar told in an interview that she was signed for the role that Mumtaz did in Ram Aur Shyam but he himself asked her not to do that role. She appeared in a cameo opposite her husband in Duniya (1984), wherein the song "Teri meri Zindagi" became very popular. Faisla which was eventually released in 1988 and is officially her last film.
