Hai Jawani Toh Ishq Hona Hai is David Dhawan’s last film. David Dhawan is saying adieu to filmmaking after Hai Jawani Toh Ishq Hona Hai.“Bass abb bahot ho gaya. I am 76. I’ve made 46 films. Most of them were successful. I hope my new film too will be liked. I am sure it will. I’ve poured my heart and soul into it. I’ve always believed entertainment is the primary reason for cinema to exist,” says David.He’s often been asked to change his formula. But David feels there is no need. “Why fiddle with the bonnet when your car is running smoothly? The David Dhawan formula, has always worked. Why should I change it? My guru and mentor Manmohan Desai also had his style. When he tried to move away from it (in Aa Gale Lag Jaa), he was rejected.”Where does David place Hai Jawani Toh Ishq Hona Hai in his repertoire? “Are you asking if it is my favourite? Right now, yes. All my films are my favourites. Even the less successful ones like Yaarana and Mr & Mrs Khiladi. I’ve always put myself with the audiences in the movie theatre and made what they like.”About making films with his son, David says, “Varun is very talented and hardworking. If he wasn’t, I wouldn’t work with him. On the sets, we are totally professional. In fact, I am stricter with him than with other actors.”So, what does David want to do now? “Play with my grandchildren. Spend time with my wife, which I never did all these years while working round the clock. And yes, watch lots of movies. No, not my own.”
