The documentary 'Angry Young Men' highlights the crucial role of screenwriters Salim-Javed in Amitabh Bachchan's rise to fame, particularly through the film 'Zanjeer', which was pivotal in changing the course of his career. Initially, the lead role was rejected by Dev Anand due to concerns about the film's lack of songs, which frustrated director Prakash Mehra. Salim-Javed recognized Amitabh's potential after seeing his performance in 'Bombay to Goa', leading to his casting as Inspector Vijay. Jaya Bachchan, who played opposite Amitabh, expressed her initial reluctance to join the male-centric film but was ultimately persuaded by the writers and the opportunity to work with Amitabh. The documentary reveals how Salim-Javed advocated for their recognition in the industry by insisting on their names being credited on 'Zanjeer' posters. This film marked a significant turning point not only for Amitabh but also for the way screenwriters were acknowledged in Bollywood.
