Mr Krishna, originally Ghattamaneni Sivarama Krishna, was one of the top actors of his time. He had begun his career in early 1960s and acted in 350 films.
He was also a successful director and producer. Mr Krishna was honoured with the Padma Bhushan in 2009.
Known for his good-nature and courageous decisions, Mr Krishna earned ever-lasting fame with his portrayal of the role of Alluri Sitarama Raju, a legendary freedom fighter in coastal Andhra Pradesh.
