"It's really not that kind of a film in the first place, it's not a 'Dabangg' or 'Rowdy Rathore'. It's a very real film and the story exists in a very real space. So, the effort on the character has also been to try and make him as real as possible," the 30-year-old said here in an interview.
"My endeavour has been to try and make people believe that this is someone who exists in the world that they belong to. Nowhere in the film will you see a film or cinema cop that these commercial flicks are used to portraying," he added.
Prithviraj said the main challenge for him was to convince the audience that his character is a true north Indian, Hindi speaking policeman.
"Playing a cop was not a challenge because this is my 15th or 16th cop film. The challenge for me personally was to convince whoever sees this film, that I am a north Indian policeman," Prithviraj said.
He put in a lot of hardwork polishing his Hindi diction for the Yash Raj Films' project.
"All the effort that I had to put in prior to the shoot was to get my Hindi diction right, and to speak Hindi like somebody who speaks Hindi on a daily basis. For that, I worked extensively with a wonderful diction coach (named) Vikas Kumar," said the actor, whose last Hindi project was "Aiyyaa".
It is slated to release May 17.
