Sanam Teri Kasam

Nasir Hussain (uncle of Aamir Khan and father of Mansoor Khan) made a couple of films with the same storyline like Phir Wohi Dil Laaya Hoon with Joy Mukherjee and Asha Parekh. Sanam Teri Kasam is a remake of these movies. A man suspects his wife of having a affair. She leaves him taking her son with her. Man comes to know that his wife was innocent and searches her but she doesn't want anything to do with him. He adopts a girl and brings her up and becomes rich. Now the son is grown (Kamal Hassan) falls in love with the adopted girl (Reena Roy) and the father is against the union. The father thinks that someone else is his son (Ranjeet) and wants Reena to marry his son. If it had not been for R.D. Burman (another Nasir Hussain standard) this film would be forgettable. Gems like Sanam Teri Kasam (by kishore and a version by Asha), Jaana O Meri Jaana and other songs make this film watchable.
