Viswambharan was ailing for some time, and his condition worsened Tuesday. The funeral will take place at Palakkad.
In a career spanning close to four decades, Viswambharan directed close to 60 Malayalam films. He quit movie making after "Puthooramputhri Unniyarcha", which was released in 2002.
Viswambharan started as an assistant director. For a decade, he worked with veteran Sasikumar before turning a full-fledged director in 1976 with "Ozhukkinethire". Since then he has given numerous box office hits.
Superstars Mammootty and Mohanlal hit stardom with Viswambharan's films.
Some of his hits include "Chakara", "Ee Sabdham Ennathe Sabdam", "Thirakkil Alpasamayam", "Kattu Kuthira", "Ezhupunna Tharakan" and "Gajakesariyogam".
