before the shooting of the film, the director and his team visited nearly all the known murder sites, like the area surrounding tilak hospital in sion, the gandhi market near king's circle, the area outside matunga police station, rafi ahmed kidwai road in wadala and one small street in lalbaug. the visits to these sites were made late at night to enable the creative team to absorb a feel of the area and the eerie late-night ambiance, which was later recreated in the film in terms of location selection, photography and the general styling of the film.
