Zanjeer (transl. Shackles) is a 1973 Indian Hindi-language action crime film directed & produced by Prakash Mehra and written by Salim–Javed. The film stars Amitabh Bachchan, Jaya Bhaduri, Pran, Ajit Khan and Bindu. The music was composed by Kalyanji-Anandji, while cinematography and editing were handled by N. Satyen and R. Mahadik.

Zanjeer was the first of many collaborations between Salim–Javed and Bachchan. Ever since Zanjeer, Salim–Javed wrote many of their subsequent scripts with Bachchan for the lead role and insisted on him being cast for their later films, including blockbusters such as Deewaar and Sholay, establishing Bachchan as a superstar. In addition to being a turning point for Bachchan's career and Hindi cinema, Zanjeer was also a turning point for South Indian cinema, with Bachchan's acting inspiring Rajinikanth. Zanjeer remains an important film in the history of Indian cinema and is regarded as a classic today.
