Avishkaar (English: Discovery) is a 1974 Hindi movie. Produced and directed by Basu Bhattacharya, the film stars Rajesh Khanna and Sharmila Tagore. The film was the part of Basu Battacharya's introspective trilogy on marital discord in an urban setting, which included Anubhav (1971) and Griha Pravesh (1979) The movie was critically acclaimed with critics giving it five out of five stars in the Bollywood guide Collections. The review by the newspaper Hindu quoted "Here you can see Khanna inhabiting a disillusioned husband with all the details. There is nothing trademark 'Kaka' here as you only see Amar with all his frailties come alive on the screen. It must have being challenging for the raging star to pick a role where he was not the hero in the conventional sense." The film was a box office hit. Khanna waived 70% of his remuneration to star in this project.The critics from the Internet site 'Scroll.in' quoted "Aavishkar is indisputably Rajesh Khanna's film. Through a fog of cigarette smoke, Amar's fixed gaze communicates the dullness of fatigue after the shattering of his inner world. When he speaks, his voice is low, and in two confrontational flashbacks with his hostile father-in-law, Khanna's performance peaks. The superstar's superb performance in Basu Bhattacharya's domestic drama proves his unexplored talent at stasis."
