When the film was first offered to Jeetendra, he was to play the double role of father and son. Later Jeetendra decided if Dilip Kumar could do the role the film could be sold for more. That is when Jeetendra went to Dilip Kumar and offered him the film.
After about 10 years after Bairaag, Dilip Kumar and Kader Khan came together in Dharam Adhikari, later they were also seen together in Kanoon Apna Apna in 1989. They were seen together in Bairaag, Dilip Kumar had given Kader Khan a role. They also had shot some scenes together for filmaker Nasir Hussein's Zabardast, which was shelved.
In those days Kader Khan always used to write dialogues for all south films but for this film Rajendra Krishan wrote the dialogues instead of Kader. Khan.
After years Dilip Kumar did a film from the south. After Dharm Adhikari Dilip Kumar last time acted in South film Kanoon Apna Apna.
