Mumbai: Actor Irrfan Khan, who is busy promoting his forthcoming film "Madaari", says he doesn't enjoy promotional activities as they don't come naturally to him. "I don't enjoy promotions, but it's my responsibility," Irrfan said. "The most difficult part of filmmaking is promoting it. It doesn't come naturally to me. I am not a very good talker. I don't enjoy talking so much, but I have to do it because this is my responsibility," he added. Irrfan even went to his hometown Jaipur to spread a buzz about the film, apart from going to the set of TV show "Chidiya Ghar". Miraj Entertainment and Bharat Shah, in association with EaseMyTrip.com, are presenting "Madaari", a Paramhans Creations production. The film is directed by Nishikant Kamat and is all set to release on July 15.
