The film was super hit at box-office and ran for more than 125 days.
This movie is the sixteenth collaboration between M. G. Ramachandran and Pa.Neelakandhan.
Tamil Film had some few scenes different from original movie like
Ranjith (Rajesh Khanna in Hindi) kills the doctor who has treated his gunshot wounds, whereas Ranjith (MGR in Tamil) lets the doctor leave his place alive. MGR-Ranjith is portrayed only as a thief and not a murderer.
In the final court scene, Ranjith (Rajesh Khanna) is identified by Bhola's dog in Hindi version where as in Tamil version Ranjith (MGR) convinces everybody that the dog is lying. He is finally trapped on seeing his mother (Kanthimathi) lying dead and he reveals himself by exposing his love for mother.
Tamil version has a story why MGR-Ranjith has become a diamond thief with a small flashback in his childhood (played by Baby Rajkumari) which is not in Hindi movie.
