Due some misunderstanding between producer Rajkumar Kohli and the director of the film Naresh Kumar (rajendra kumar's brother) Rajkumar Kohli decided to complete Gora Aur Kala himself and he had decided from then onwards he would direct his films himself, and he wont sign somebody else to direct his films, so then he started to produce & direct big films and became successful like Kahani Hum Sab Ki, Nagin, Jaani Dushman, Muqabla, Badle Ki Aag, Nauker Biwi Ka, Raaj Tilak etc.
This film was a remake of the Tamil film "Neerum Neruppum" (1971) starring M.G. Ramachandran. The Tamil film itself was the remake of another Tamil film "Apoorva Sagodharargal" (1949), which in turn was based on Alexandre Dumas' French novel "Les Freres Corses" (English: "The Corsican Brothers"), first published in 1844. "Apoorva Sagodharargal" (1949) was part of a trilingual production which was released in Telugu as "Apoorva Sahodarulu" (1949) and in Hindi as "Nishan" (1949). "Neerum Neruppum" (1971) was also dubbed in Hindi and released as "Aakhri Nishan" (1973).
The film was inspiration for Jackie Chan movie Twin Dragons.
