This film was an uncredited adaptation of the hit Kannada thriller "Premada Kanike" (1976) starring Rajkumar. Salim - Javed, who wrote the story of the Kannada film, were not credited in this film. "Premada Kanike" (1976) was also remade in Tamil as "Polladhavan" (1980) starring Rajinikanth. Interestingly, the story of "Premada Kanike" (1976) itself was rehashed from Salim Khan's debut film as a writer, "Do Bhai" (1969).[1]
Song
Tum Jo Hamen Itni Pyari Lagti Ho - This was a rare Hindi film song which was sung by three real-life sisters - Sulakshana Pandit, Vijayta Pandit and Rashi Pandit. While Sulakshana and Vijayta Pandit were successful actors, this song was the only contribution of Rashi aka Sandhya Pandit Singh to Hindi films. Sandhya Singh was in the news in 2012 when she was reported missing. Her son Raghuveer, who had a drug abuse problem and frequently quarrelled with his mother, was arrested in 2013 on the charge of murdering her. He was let out on bail in 2015.[2]
