Watch Suresh Gopi and Manju Warrier in Kaliyaatam. It’s an old movie but if you liked Omkara you may like it.
1) Amitabh Bachchan. Hindi movie. 1970's-80's. 2) Heroine has an incurable disease. 3) Was remade in Telugu with Jayasudha as the lead.
No ... Don was remade as Yugandhar starring Jayasudha but the heroine is not suffering from a disease in Don/Yugandhar...
