Basu Bhattacharya's wife Rinki Roy stated "Dinesh Thakur, who played the other man, also assisted Bhattacharya. He lived next door to him and was in and out of their home. However, a young Amitabh Bachchan came very close to being cast in the film."Just when Basu had confirmed Thakur, I saw Amitabh Bachchan. He hadn't started working and I saw him at a reading of his father Harivanshrai Bachchan's poems on the terrace of Dharmyug magazine editor Dr Dharamvir Bharti's house. Amitabh was standing and everyone else was sitting. I just looked at him and told Basu, 'This guy has a lovely voice, he would fit into the other man's role.' But he already had Dinesh," Rinki said.
Pran signed the film and shot for it for a week. Basu Bhattacharya realized Pran did not suit the role of a average working class man. He replaced him with Sanjeev Kumar. Problem was that Basu did not inform Pran of being dropped from the film. When Pran finally found out, he nearly bashed Basu Bhattacharya at a party .
The film had a small budget and was shot in Tanuja's apartment.
Singer Subir Sen appeared in a cameo role in this film playing himself. He sang Rabindranath Tagore's Bengali song "Se Din Dujone" and performed it on the screen. The song was not part of the film's audio release.
This was the first of Basu Bhattacharya's trilogy of films which told stories of marital discord in modern, urban families. The other films in the trilogy were "Aavishkar" (1973) and "Griha Pravesh" (1979). All three films had music by Kanu Roy. Ironically, for someone who depicted marital life with great sensitivity, Basu Bhattacharya himself had a tumultuous married life. He married Rinki Bhattacharya, the daughter of his mentor, director Bimal Roy, in 1961 against the wishes of Roy. After years of abuse, Rinki left Basu Bhattacharya in 1982 and went on to make documentaries and write extensively on the topic of domestic violence. The couple got formally divorced in 1990. .
