Rajesh Khanna saw the rushes of the film and got very angry. He felt Shakti Samanta had given Vinod Mehra more footage in the film. He demanded more scenes be written for him. This altered the script and the film failed.
For the first time and the only time Shakti Samanta had taken Laxmikant-Pyarelal for Anurodh. But after this film Shakti Samanta had continue to take R.D.Burman for his films till his one of his last film Dushman in 1990. Shakti Samanta had also taken Ravindra Jain for 2 films Khwab & Ayyash.
The film is based on the 1963 Bengali film "Deya Neya".
The film didn't do as much business as was expected because people could not accept Rajesh Khanna doing romantic scenes with Simple Kapadia, who was his sister-in-law in real life.
Vinod Mehra received great critical acclaim for his performance outshining Rajesh Khanna & he went on to receive the Filmfare award nomination for Best Actor in a supporting role in 1978
