Mumbai, Aug 9 (IANS): Bollywood superstar Shah Rukh Khan's "Chennai Express", which released on the auspicious occasion of Eid-ul-Fitr Friday, says he can't stop smiling thanks to the overwhelming response to the movie.

"I can't stop smiling. Till the time I don't stop smiling, the excitement won't settle down," Shah Rukh said at a press conference held here Friday.

The conference was held at the compound of his Bandra bungalow Mannat, and he was accompanied by "Chennai Express" director Rohit Shetty.

Shah Rukh said he is happy with the initial response, but he wants to wait for some more days to see how the film sustains.

"It is nice that the film is doing well. I want to wait for three to four days. I am happy that people have liked the film and it has opened well," he said.

However, he didn't know about the film's success in terms of numbers.

"I don't know how much (business) it has done till now. I just woke up. If a big film releases, I try to refrain for at least two to three days (from counting the collections)," he said.

"Chennai Express" has a positive message for women, and Shah Rukh says he is glad it has been able to depict the message in a convincing yet subtle way.

"The film has a message, but it is not on the face. The film is a made up story. She (The female character played by Deepika Padukone) is a strong woman who runs away from home. We have made a point in the film without making a point of it," he said.

The film has several Tamil dialogues, but sans subtitles. It was a conscious decision, SRK said.

"The idea was to show the audience what the hero is going through. Also, love has no language. If we start explaining, then the point is lost. It will spoil the creativity," he added.
