The director recently showcased Gangs of Wasseypur at the 65th Cannes Film Festival.
"The general complaint from the Indian audience we hear about these films is that 'it is slow' while in west these films get packed houses and the audience sit through the entire film," he told audiences at the Jawaharlal Nehru University campus.
"I know what a tough time I went through after making Black Friday. Films like Paan Singh Tomar had to wait for more than a year to see their release in theatres, and that too only after we started promoting the films through word-of-mouth and on social media like Twitter.
"Cans of films in the industry made by various filmmakers are still lying unopened because there are no takers. In fact, more than me, it's my office which is celebrating the success of Gangs of Wasseypur as they believe now other such films might see the light of day."
It was reported today that Gangs of Wasseypur is to be released in the Middle East and France after getting a good critical reception.
In May, Kashyap said that western cinema-goers no longer think Indian cinema is just about song-and-dance numbers.
