This is the first film signed by Zeenat Aman.
Debit of Kabir Bedi and Zeenat Aman.
Kabir Bedi signed the film thinking he was the lead actor. When he asked Ralhan for the script, Ralhan yelled at him. Ralhan told Kabir he was the one who made Dharmendra a super star. Kabir should sign the film and not ask any questions. But in reality, O.P. Ralhan was the lead actor. When the film flopped, no one blamed Kabir Bedi as he had a small supporting role.
Years later film was made in Marathi as Murder Mestri 2015.
One of Amrish Puri's earliest movies, he played the role of a public prosecutor. This is one of 3 movies he did with the same title, he played the main antagonist in 1995 which starred Vinod Khanna and Ajay Devgan and one of his final movies which starred Akshay Khanna and Kareena Kapoor.
