Some of these stories have been myths while others are facts but Bhatts and director Mohit Suri have tried to incorporate those elements which are the most intriguing", informs a source, "You pick up any major city in India and it has it's own story to tell when it comes to such serial killings. Mumbai has its own share while Delhi too has it's own. Goa setting comes into picture here because it again has a history of serial killers." The film was shot in Mumbai and Goa. Earlier, Bipasha Basu was offered the part of the leading lady, but she refused. The part then went to Jacqueline Fernandez.
