This film tells the story of a widow Sheetal (Hema Malini) who is left devastated after the death of her husband Raj (Rajesh Khanna). She is left with one child to look after and teaches in a school and one of her students is the daughter of the widower Ravi (Shammi Kapoor). The children become instrumental in getting the single parents to meet and fall in love.
Andaz was one of the last movies for which the great music directors duo, Shankar- Jaikishan composed music together. Jaikishan died of cirrhosis of the liver on 12 September 1971 at the young age of 42. Coincidentally, one of the most popular songs from this film - Zindagi Ek Safar Hai Suhana, Yahaan Kal Kya Ho Kisne Jaana (Life is a beautiful journey, One never knows what's going to happen tomorrow) turned out to be the last song that Jaikishan recorded before his death.
Andaz also proved to be the last hit for Shammi Kapoor as a lead hero. Even the success of this movie is credited to the Rajesh Khanna Mania of the 70's, as Rajesh Khanna only appeared for five minutes in the movie, and still created a stir. However, Shammi Kapoors performance was well received and it has been one of his most uncharacteristic roles of his career.
