Cinematographer Satyajit Pande brings the many vignettes of Kolkata alive in this thriller, which has Vidya Balan going through the city looking for her missing husband. In the film, the city is a character, not just a backdrop. Shot extensively in Kolkata, it features the usual Victoria Memorial, hand-pulled rickshaws, and the Howrah Bridge, along with places that are generally not featured in films. Sure, the actors steal the show, but so do the cameos by several Kolkata spots like Kalighat Metro Station. Mona Lisa Guest House in south Kolkata, where Vidya Balan stayed in the film, still invites bookings. The festival of Durga Puja plays a big role in the film, from the half-finished idols of Durga in the ancient potters colony of Kumartuli to the climax which was shot in the chaotic backdrop of the last day of the festivities.
