Both Khan and Sharma had to undergo significant physical transformation to play their characters in the film, and the trailer shows precisely that. Khan comes out as a ruthless, no-bars-held cop who will stop at nothing to rout out crime. Khan looks exceptionally buff and is back in a Sardar persona, a character he has played before in ‘Heroes’. The trailer also gives the audience a good peek into the transformation of Sharma's character, the nemesis of Khan in the movie. The evolution of Sharma in the film from being an innocent young boy to one of the most aggressive, dreaded and territorial gangsters is what the movie promises to be all about.
