Actor Atharva Vishwakarma (Josh Mascarenhas) was not given a written scene with dialogues throughout the shoot. He was always explained the scene and it's context, so that his childlike innocence could be captured.
In order to look exhausted for the nightmare scene, Amit Sadh didn't sleep the night before the shoot.
Co-incidentally, actor Jayshree Venkataraman is also from Delhi and has been living alone in Mumbai for the past three to four years.
