Two sequels, two superstars, this Independence Day will see two big films clash at the box office. With `Gadar 2` and `OMG 2` set to release on August 11, Sunny Deol and Akshay Kumar are set to face each other at the box office. 

The advance bookings for both the film was started almost two weeks before its release. Going from the advance bookings, it seems like `Gadar 2`, driving high on nostalgia, will have a massive opening day.
