Saat Khoon Maaf started on the lower side as most would expect. The opening was around 30-35% on average at multiplexes and 15-20% at single screens.
An interesting comparison will be No One Killed Jessica released a few weeks back which started lowly but picked up in the evening and went on to do well at the box office. That film was also heroine orientated and had a similar release though Saat Khoon Maaf does have the presence of known male stars in small roles while No One Killed Jessica had no male leads.
Saat Khoon Maaf will not score in single screens and will be dependent on multiplex business in the big cities.
