It was at a teachers workshop at a local school here when Chetan got fascinated with the use of camera after he saw a person recording the session.
"I had no knowledge about films and how to make films. But the way camera was used I was keen on trying my hands," Chetan told PTI.
It was his 1988 play titled "Chespay Khachat" that Chetan turned it into a feature film following an overwhelming response from people here.
"The play got good response so I made it into a feature film and added some commercial aspects like song and dance," he said.
