David is in the mood to whisk away his younger son for a home production, to be directed by his elder son Rohit Dhawan of Desi Boyz fame, says a source. David is excited about the response to his son’s performance. “I’ve a director and a leading man at home. I am very keen to start my own home banner. But I had to wait. Neither of my sons wanted to make his debut in a home production. They wanted to prove themselves outside the comfort zone,” he says.
