This is Bhardwaj's second consecutive National award win. He won the best screenplay (dialogue) award last year for 'Haider'.
"This is my seventh award National award. I am very happy this time as it's a for a film like 'Talvar', whose story needed to be told. This is my second film alone as a writer so it gives me confidence, a boost to write," Bhardwaj told PTI.
The 50-year-old filmmaker, who is currently shooting for upcoming period drama 'Rangoon', said he will celebrate the win with his team.
"Initially when my producer told me about the award I couldn't believe it I wanted to hear (it on TV) and see it myself. The congratulatory messages made me feel it's true. In the evening I will party with my team."
