Before the song Roop Mein Nikla Na Karo in the film Gereftaar, there is a romantic scene between Amitabh and Madhavi. During that scene "Rangila Ratan Theme Part 2" is played as background music. It is from the soundtrack of the movie Rangila Ratan starring Rishi Kapoor and Praveen Babi
This film was financed and presented by Ratan Khatri, the head of an illegal gambling network that operated out of Bombay. He also had an acting role in the film. It is possible that the title of this film referred to Khatri himself. Khatri, who came to be known as "Matka King", had earlier consulted with Feroz Khan for the character played by Prem Nath in the film "Dharmatma"
