Varma chose a house in Mumbai for the shoot. The first owner of the house had committed suicide in the premises. The current owner willingly gave the house to Varma for the shoot with a promise of not giving out the address of the house in the movie or the media.
The cast of the movie got quite spooked after Varma told them that it was a haunted house. They used to try and stay together for night shoots.
"We got to know the house has a history after we started shooting for the movie. The cast and crew did get a little spooked and scared when they came to know that someone had committed suicide in that house. I, for myself, was too busy trying to scare so never got time to get scared myself," Varma said in a statement.
