prem ratan dhan payo release date :November 12, 2015
Prem Ratan Dhan Payo should get the highest opening day as its the biggest day of the year for box office collections.
Happy New Year released on the same day last year so Prem Ratan Dhan Payo should add a little to the Happy New Year numbers of last year. It is a Thursday release rather than Friday but that should not make a difference.
As for lifetime records or 400 crore its pointless predicting before release as every big film has a chance but doing is another thing. Even if a 40 crore nett first day came, 400 or 350 crore nett is far away, even 300 crore nett is far away.
