A source said, "Harman does not smoke in real life. In fact he feels that smoking should be banned all over the world. But lighting his first cigarette was quite an experience for him."
The source added, "Harman balanced the cigarette between his fingers and tried to light it. Only it was from the wrong side--the side from which one inhales the puff. Harman made it look absolutely realistic on screen."
As for his personal concern Harman is leaving no stone unturned to bring about an awareness in global warming. "Harman firmly believes that if the destination is the same then everyone should travel in one car rather than different cars, " said the source.
