John Abraham will be seen essaying the role of a chain-smoking cop in ''Dishoom'' and we hear that for his role in the film, the actor ended up lighting over 600 cigarettes during the shooting schedule! Though John is a non-smoker and very particular about his fitness, the hunk readily agreed to smoke for his role. John quipped, “Character comes first and because it demands so, I am smoking. We do not encourage smoking at all. My character in the movie is that of a chain smoker and a lot of scenes in the film required the smoking bit."
