Shah Rukh Khan left no stone unturned to promote Chennai Express but the superstar, who made exhaustive rounds to all the popular TV shows, did city and world tours, held live chats to create a buzz about his latest outing, says he is not an expert in marketing. The 47-year-old actor says he simply likes to inform his audience about his films. And it seems that SRK's efforts have paid off in a huge way as Rohit Shetty directed film has become the fastest entrant into the elusive 100 crore club despite garnering average reviews from the critics. "I am not a marketing guru or a romantic hero. I promote my film to inform about it to my audience. I feel since they had to shell so much money to watch a film, they have the right to know about it. I inform my audience and give a brief overview of it," Shah Rukh told PTI. The actor's last similar promotion blitzkrieg was for his home production Ra.One.

"I promoted Ra.One fanatically because it was a new genre in India. I didn't promote Jab Tak Hai Jaan much because it was a love-story and Yash uncle's sudden death upset me. I have been talking about Chennai Express a lot because many think it's an action film but its an out and out comedy. I love to live with my films," he added. Shah Rukh, whose banner Red Chillies Entertainments co-produced Chennai Express with Disney-UTV, is on cloud nine after the film's success at the box office. "It's a good sign for Bollywood and I am happy with the business part of it. The film has done good overseas and has done good as compared to a Hollywood film (I am not comparing my film with Ironman or Superman). It shows that our films have a huge market overseas," he said.
