Tamil Cinema Box Office

[Munsamy]

While Ajith is well ahead of Vijay in first day opening, Vijay trumps in the family audience space easily. Even in this diwali case, there will a momentum shift after the first 2-3 days - unless the theatres are blocked for days in a rigid manner!

Opening depends on hardcore fans and star power. That's where Ajith and Rajini are head and shoulders above everyone else
