Cinemas, schools and film studios have been closed for two days in the southern Indian state of Karnataka to mark the death of film superstar Vishnuvardhan at the age of 59.

The popular actor and singer, who starred in 199 movies in his 37-year career, died early on Wednesday of a heart attack en route to hospital where he was being taken after complaining of leg pains.

Thousands of his fans lined up at Basavanagudi National College in Bangalore were his body was laid out for public viewing prior to an evening state funeral at the Abhiman studios and cremation.

The Times of India reported that some people in the crowd turned unruly during the processions to the college and the studio, throwing stones at buildings and vehicles. The violence continued into the evening, despite public pleas for order from the late actor's widow, the actress Bharathi.

"He loved peace," she said. "I request all his fans to maintain peace."

Four police officers and several people were injured, and about 50 vehicles were damaged.

Ironically, the subject of all the uproar was a mild-mannered, deeply spiritual man who was well liked by his fellow performers.

Born Sampath Kuman in Mysore in 1950, Vishnuvardhan changed his name when he launched his film career with the 1972 movie, Nagarahavu.

He won seven state awards, five Filmfare awards and received an honourary doctorate from Bangalore University.

His 200th film, Apatha Rakhshaka, will open in the new year.

Vishnuvardhan is survived by his wife and daughters, Keerthi and Chandana.
