Filmmaker Anurag Kashyap's expertise lies in making different kind of cinema and he candidly admits that if he is given a task to make a film like "Rowdy Rathore", he won't be able to do it.

"I can't make a 'Rowdy Rathore'. If I make a 'Rowdy Rathore', it will be a flop. It has to be made with a conviction. Prabhu Deva had a conviction. He believes in what he is doing. You need to believe in what you are doing.

The day I start internally believing in a film, which is in the mainstream zone, I will make it," Kashyap told reporters Tuesday at a press meet.

Kashayp says that as a filmmaker he feels whenever a film makes money at the box office because that mone is used for the promotion or making of other films.

But at the same time he feels audiences should encourage a film like "Shanghai" too.

"I am sad about people not watching 'Shanghai', but I will not be sad about any film making money. UTV is making money out of 'Rowdy Rathore' and they will spend that money to promote my film 'Luv Shuv Tey Chicken Khurana'," he said.

"Today Viacom 18 is spending money on 'Gangs of Wasseypur' because they have earned enough money from 'Kahaani'. So I am not sad about any film making money, but yes it does make mefeel rethink when 'Shangahi' does not do the way I hope it would," he added.

Dibakar Banerjee's "Shanghai" is a serious film that talks about problems in the country and it opened to rave reviews, but the box office response has not been so overwhelming.

"I sat down with Dibakar a day before and he said this will be the scenario. I was hopeful and I am always an optimist. 'Paan Singh Tomar' turned around and did something which I am really happy about. 'Shanghai' did not and I am still hoping. I don't think that I will be ever sad about 'Rowdy Rathore' making money," he said.

Meanwhile, part one of Kashyap's crime thriller "Gangs of Wasseypur" is ready to release June 22.
