There are bound to be differences of opinion over anything new... and when people have views on an issue, it creates a discussion, which becomes a controversy,' he said in a nonchalant tone.

With 'Agyaat', the filmmaker is set to experiment with a genre he has never done before, Varma said.

''Agyaat' is an adventure thriller'. It is about an unknown creature killing people in a jungle. That's why it is called 'Agyaat'. It's a genre I have not done before and to my knowledge, it has never been done in Bollywood. It may be a slightly scary, but doesn't fall under the category of a 'Phoonk' or 'Bhoot',' he said.

To keep the thrill, suspense and spook alive in 'Agyaat', Varma has used several sound effects instead of using heavy make-up and unique costumes for his invisible scary character in the movie.

'Fear can have many manifestations. It's not necessary that you can create it only through ghosts. You can hear a voice and build a lot of fiction around it. That is what I want the audience to respond to - the sounds. Often, in such situations, the mind becomes a monster and that is something that can really scare you.

'Otherwise, what happens to stringent inter-personal relationships in the face of death in a jungle is what forms the climax of the movie,' he said.

'Agyaat' is a story based in a jungle where a film crew goes for shooting and gradually each one starts getting killed under mysterious circumstances.

It features actors like Gautam Rode, Priyanka Kothari and Nitin Reddy.
