1978, Telugu, directed by K Balachander
This was the original for Ek Duje Ke Liye (1981), which was also directed by K Balachander. The Telugu film ran in Chennai for two years. Here the boy was Tamil, the girl Telugu. It was in black and white and I preferred it. The Hindi version was a little flashier, it had a Punjabi girl and a Tamil boy. The heroine (Saritha) was simple-looking but a fantastic performer.
