Gyan Dev Agnihotri wrote all the dialogues and was the Assistant Director for this 1973 Indian Art Film Avishkaar, conceived, written (screenplay) and directed by Basu Bhattacharya. The music was composed by Geeta Dutt's brother Kanu Roy for two beautiful songs "Hansnay kee chaah nay kitnaa mujhay rulaayaa hai" (Manna Dey) and "Nainaa hain pyaasay meray" (Asha Bhosle) both written by Kapil Kumar. The classical song "Babul Moraa Naihar Chhootoe jaayay" written by Nawab Wajid Ali Shah (ruler of Awadh, Mughal India) in the mid-1880s and sung to critical acclaim by Pandit Bhimsen Joshi and to popular acclaim by Kundan Laal Saigal (1938 movie "Street Singer") was also included in the movie "Avishkaar"... here it was sung by Jagjit Singh and Chitra Singh and helped revive this old song's magic to enrich the movie.
Avijit Ghosh, Senior Editor, The Times of India, mentions interesting anecdotes about the making of "Avishkaar" in his 2013 book ("40 Retakes: Bollywood Classics You May Have Missed" Tranquebar Press and also available as an eBook on Google Play Books) including the fact that Kapil Kumar wrote "Hansnay kee chaah nay kitnaa mujhay rulaayaa hai" while riding a Bombay mass transit bus and used the backs of bus tickets to write the lyrics that were coming to him and later showed it to Basu who immediately liked it and included it in Avishkaar as a song.

Basu Bhattacharya had always been obsessed with the subject of marital discord (made three movies on marital discord: Anubhav, Avishkaar and Griha Pravesh). Basu got the idea of Avishkaar from watching the five hour Art Film "Scenes From A Marriage" starring actress Liv Ulmann and directed by Ingmar Bergman.Basu wanted Avishkaar to be true to his own life and wrote many scenes which were taken from his actual marital life and even shot the whole movie at his apartment in Bombay with some scenes at the church and park where he and his wife (Rinky Roy, daughter of Bimal Roy) actually met at dawn one day before their marriage.
