"He directed 16 films. He always treaded a different path and that's what made him different. He was a known Left traveler, that was evident in most of his pictures. His unexpected demise has come as a shock. The Malayalam film industry would miss him," said Balan.
He was fielded from the Ottapalam Lok Sabha constituency by the CPI-M twice in 1989 and 1991 against K.R. Narayanan.
He won five Kerala state film awards in his career.
