Kaala Patthar is a 1979 Indian Bollywood disaster drama film, based on the Chasnala mining disaster. It was produced and directed by Yash Chopra, with a screenplay written by Salim-Javed. This film is the fourth collaboration between Amitabh Bachchan, Shashi Kapoor and director Yash Chopra after the hugely successful Deewaar (1975), Kabhie Kabhie (1976) and Trishul (1978). However, this film did average business at the box office. It was nominated for 8 Filmfare awards. While Rajesh Roshan composed songs for the lyrics penned by Sahir, the background score was composed by Salil Chowdhary.
