Director Sujoy Ghosh has a penchant for thriller movies. Inspired by Hollywood or South Korean flicks, the director has come up with his own dish of desi suspense dramas. Interestingly, the director started his career in the Hindi film industry with the musical 'Jhankaar Beats' which turned out to be a hit. But he is best known for the path-breaking Vidya Balan-starrer 'Kahaani', which in a way changed the scenario of suspense dramas in the Hindi movie industry.

In an interview with Mashable India, Sujoy Ghosh shared the challenges he faced during the film's production due to a tight budget. He said “You have no idea. We didn’t have any budget to even afford a vanity van. We didn’t have the luxury of pausing shoot because we were on a tight budget. So, every time she had to change, we used to cover her Innova with a black cloth, in the middle of the road, and she used to change inside and come out for shoot.”
