VIJAY PLAYS A DEADLY 'LA DIRTY HARRY' TYPE COP!

It was smart packaging by AR Murgadoss and Vijay. They went for a conventional and traditional poster look for the film, which seems to have worked big time with the fans of the actor.
The Santosh Sivan shot poster told the essence of the film, with all the writing in the background- Mumbai, mobile network jammed in Mumbai, grisly, beheaded, hospital secrets, vandalism, body found dead etc.

In a freeze frame the story is clear that it is set in Mumbai and Vijay plays a deadly ‘la Dirty Harry’ type cop with a different look and smoking a Cuban cigar.
