Sivan, 49, is known for making period films like 'Asoka', 'Urumi' and 'Before the Rains'.
"Its a great feeling. I am very happy and excited. I have been flooded with calls since it was announced. It's good to get all these congratulatory messages from my near and dear ones," Sivan told PTI.
However, the celebrated filmmaker has no regrets for not receiving the award earlier.
"For me the thing which is most important is that whenever we receive an award your heart must believe in it," he said.
