Sharing similar sentiments, director Nikhil Advani said, "The film is not about underworld, it is not about bhaigiri. It is a spy thriller... There are RAW agents. It is about four patriots who go to bring back India's most wanted man."Arjun is happy with the response the film's promos has received."We got lot of positivity after releasing the first look. As it appears as a different story, there is interest among the audience about the film," he said.Though, several films have been made involving RAW agents, Irrfan insists D Day is different and a step ahead of others. "The nuances of that profession is shown in detail in the film. People will get to know as to how the intelligence services operate... Like how they pass information, an advertisement is placed in a newspaper, how things are decoded," Irrfan said."My character has his own life, has family. They never reveal anything even to the closest of people," he said.The film opens in theatres on July 19.
