Sarah Jessica Parker has revealed that fans of the TV show Sex And The City may be shocked by the seriousness of the movie version.

The actress who plays Carrie Bradshaw in the hit HBO show admitted that the complexity of the storyline has left some viewers surprised.

42-year old Parker says: "What can I tell you in my own stealth way without giving the story away... A handful of people have seen it and have been very surprised by the seriousness.

"There's something that happens in this movie and it's really about realising your own complicity and disappointment."

She adds: "There's still plenty of ripe old salty dirty stuff. But I think it's a really smart story and I think Michael Patrick wrote a beautiful screenplay.

"I think we are all still figuring out what we want in terms of the movie. You know, whether it's at Cannes two weeks before it opens domestically."
