Salman observed the bodyguards of the VVIPs and the SPG (Special Protection Group). He tried to follow the body language and ways of these highly trained security personnel in charge of the security for the Prime Minister and Congress leaders Sonia and Rahul Gandhi.
He noticed how these bodyguards manage the VVIPs through the crowd and how they move about in the crowded situation and also how these bodyguards take care of these important people.
Salman wanted to give a natural touch to his character as a bodyguard in the film, therefore he made sure he learns a lot from the real bodyguard to do justice to his role. Says producer Atul Agnihotri to PTI, "Salman Khan wanted to know the body language of the SPG. These guys are trained to blend and protect Z plus personalities. All protection is an eye play. Salman, though not a franatic cricket buff,watched the Indo-Pak match without missing a second."
