Bhuvana Oru Kelvi Kuri was notable for casting Rajinikanth and Sivakumar as a hero and antihero respectively, contrary to the roles they played in earlier films.

The success of Bhuvana Oru Kelvi Kuri led to Rajinikanth playing more positive roles in films.

Aboard a train bound for Madras, Nagaraj and Sampath encounter Muthu, a temple trust clerk who has a suitcase full of cash.

But Muthu dies en route of a heart attack and Nagaraj steals his suitcase, over Sampath's objections.

Muthu's sister Bhuvana visits them at Nagercoil to enquire about the lost cash (which is all black money).

To make the rest of the money legitimate, he decides to marry Manohari, the daughter of a wealthy businessman.

A short while later, Sampath succumbs to cardiac arrest, the result of years of excessive smoking and drinking.
