O. P. Ralhan was a Bollywood producer, director, writer, actor who made several hit movies in 1960's, 70's and 80's. Among his notable achievements are giving breaks to struggling actors and also introducing new actors in his films. He gave Dharmendra his first golden jubilee blockbuster with Phool Aur Patthar (1966) and made him a star. Zeenat Aman was first introduced in Bollywood by O. P. Ralhan in his 1971 film Hulchul, although some people have a misconception that Dev Anand brought her with Hare Rama Hare Krishna. He also introduced Kabir Bedi in Hulchul. He cast Amitabh Bachchan in Bandhe Haath (1973) when he was not yet a known name. Due credit must be given to O. P. Ralhan for his achievements.
