Gulzar made Jeetendra's character wear glasses and have a mustache in the film. This was done so Jeetendra would resemble Gulzar himself.
The film opened with Koshish, where Sanjeev was opposite Jaya Bhaduri. Both films were box office hits.
Sanjeev Kumar and Vinod Khanna have special appearances in this movie.
The film was reported to be based on the Bengali novel Rangeen Uttarain by Raj Kumar Maitra.
The film was partially inspired by the 1965 movie "The Sound of Music".
