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.
