Putting behind the debacle of his last release "Bombay Velvet", Kashyap says it was liberating to work in a limited time and space because he is familiar with this style.

When asked whether the failure of his last movie was on his mind while making the serial-killing drama and whether it affected the mood of the movie, Kashyap says he is only influenced by storytelling.

"No, not at all. The mood of my film is always decided by the kind of story I am going to tell, the kind of money and time I have for it. All my life, I never had enough money to make my films. I have made films with less money. I know how to do that. That has always been my training," Kashyap told a news agency in an interview.

"If I am making 'Raman Raghav 2.0' in Rs 3.5 crore, I know how to make it look like it was made in Rs 13 crore."

Another factor that was liberating for Kashyap was taking on a more contemporary version of the Nawazuddin Siddiqui-Vicky Kaushal starrer rather than making the planned biopic on the infamous serial-killer, who operated in 1960s Mumbai.

"I knew I was not making a biopic so, I was not limited by facts. Another advantage that I had was that not much is known about this guy. I know a lot more than other people because I worked on Sriram Raghavan's documentary.

"Vasan Bala (scriptwriter) had access to a lot of research material. We had the script for the biopic for the longest time. After 'Bombay Velvet', we realised that we can't make a biopic. So, I decided to make 'Raman Raghav 2.0' and it liberated me and allowed me to play more with my story."

The 43-year-old director says the glimpses of humour that is seen in the trailer is scattered throughout the movie as he finds it a great tool to relieve tension in a story like this.

"Without humour, we can't survive anything. I know it is a very dark and disturbing film so, it is very important to have humour. It kind of gives the breathing space to the film. The humour is also dark. People laugh because they are uncomfortable, they can't figure out the character. I use it consciously.""Raman Raghav 2.0" is slated to release on June 24.
