After "Ahalya", many short films including "Kriti", "Ouch" and "Raakh" released on digital platforms and were also lauded for their crisp and fascinating content. 

Asked if he feels the digital platform is slowly taking over cinema, Ghosh told here: "Absolutely, it has to. That is progress and that is the future. I don't know if it will happen in my lifetime or not, but definitely it is the future." 

"The way the digital world is spreading and the way you are accessible and you can access, is only matter of time...When I can beam my movies straight to you at your door step, it is a one to one relationship," added the director, whose film "Kahaani 2", a thriller, hit the screens on Friday.

Asked if he has seen an evolution in the thriller genre, he said: "It is evolving...Any film that is engaging, is a thriller for me. Even when I am watching a hardcore romantic film that is also a thriller for me, as long as I invest in the characters and know more about the film. It is a thriller for me."

He says right now a "standard definition" to a thriller is given. 

"There in one murder, one investigation...I don't think we need all that. They might help, but there are other ways to represent a thriller." 

This will be the second time Ghosh will be seen working with actress Vidya Balan. Ghosh says the actress is willing to give him "company in the madness". 

"The kind of scripts I write are not necessarily very palatable, easy scripts. My scripts are normally very demanding, my style of working is very demanding. So, I think Vidya is the only one who gives me company on these journeys," he said. 

The director adds that he also finds it comfortable working with her. 

Is Vidya a director's actress?

"She is a director's actress, but best is not to direct her. That would be my advise to any director, who works with Vidya," he said about the actress, who also featured in his 2012 directorial "Kahaani". 

Does he fear that demonetisation may affect the box office collection of "Kahaani 2"?

"I saw 'Dear Zindagi' doing really good. I think it's a question of priority if people want to spend...If anything goes wrong with the film, it will be purely my fault. Nothing to do with demonetisation, nothing to do with anything. It will be because we made a bad film," Ghosh added.
