Its no secret that Rani Mukherjee is playing a cop in Mardaani. And the film obviously has a patriotic flavor to it. So, in going with the theme of the film, Rani Mukherjee is going to shoot a special national anthem video which will be played before Mardaani begins.
The video will show Rani Mukherjee standing with female police officers, and singing the national anthem to the audience. Rani will be seen wearing formal clothes (and not police uniform), but the police officers will all be seen in uniforms.
We must say that this is a very touching gesture on the part of the producers, and Rani Mukherjee.
