This is one of the five movies Shabana and Vinod Khanna were paired in 1977. AAA, Parvarish, Chor Sipahee and Adha din adhi raat were the others.
Jalal Agha stated in the media he hated Shabana Azmi for ill treating him during the making of the film. She and Vinod Khanna would gang up and make fun of him. Vinod was OK because Jalal knew him personally. But Shabana Azmi was rude and always acted like a big star.
Shatrughan Sinha would get angry when the media dubbed Vinod Khanna as the next superstar. He would argue that his film Vishwanath opened bigger than Adha Din Adhi Raat.
Actor Jalal Agha was credited as "Co-director" in this film.
This film was a remake of the Telugu film "Manavudu Danavudu" (1972) which was inspired by Robert Louis Stevenson's novel "Strange Case of Dr Jekyll and Mr Hyde" (1886). The Telugu film was also remade in Tamil as "Engal Thanga Raja" (1973) and in Malayalam as "Ithaanente Vazhi" (1978).
