Bhandarkar, who had earlier won the award for his first directorial venture Chandni Bar, said he was happy that the "National Award coincided with the silver jubilee week of the film (that was last week) and is a very big honour for me and those associated with the film".
While Chandni Bar had won four national awards, Page 3 has bagged three national awards.
Bhandarkar said he was working on his next project titled Corporate.
