Over the decades, filmmakers strived for new stories to project brother sister equation so if Ek Phool aur Chaar Kaante was about Sunil Dutt wooing his beloved/Waheeda Rehman’s brothers then Aaj aur Kal was about separated siblings reuniting in the climax. For a long time, no wedding celebration was complete without ‘Meri pyari beheniya banegi dulhaniya…’ popularised by Rajesh Khanna in Sacha Jhootha. This was an era where actresses like Naaz and Nazima made a career out of playing sister to leading heroes in film after film.
Leading ladies were always reluctant to play sisters to their heroes because it affected their romant ic pairing so Mumtaz refused to play Jasbir (eventually played by Zeenat Aman) in Hare Ram Hare Krishna even though it was a better role and remembered for the brother sister bond projected in ‘Phoolon ka taro ka….’where a young Dev Anand piggy rides a thumb sucking kid sister. Similarly, Padmini Kolhapure refused to play Mithun Chakraborty’s sister in Pyaari Behna even though a better role and eventually played by Tanvi Kher.
