Sarah Jessica Parker and her Sex and the City co-stars are set to resurrect their martini-sipping, bed-hopping characters for the big screen.

A script for a Sex and the City feature film is being penned and filming could begin later this year in New York.

A Sex and the City movie has been rumoured since the TV series ended in 2004 after six award-winning seasons, but there was resistance from the show's four leads, Parker, Kim Cattrall, Kristin Davis and Cynthia Nixon.

Mario Cantone, who played the campy, short-tempered best friend of Davis' character, confirmed a script was being written by Sex and the City screenwriter, director and executive producer, Michael Patrick King.

"There's nothing definitive yet," Cantone told AAP.

"I know the script is being written and I know it will be brilliant because Michael Patrick King is writing it.

"I know that I'm in it. I have a nice part in it, I'm told.

"If it happens, we should film it in the early fall I think, but I hope it stays on course because I would love to do it."

The success of last year's female friendly The Devil Wears Prada, which earned $US320 million ($A412.98 million) at the international box office, renewed interest in the Sex and the City movie.

"I think there's an audience for it," Cantone, a Tony Award-nominated Broadway star and regular on the US TV talkshow, The View, said.

"There are girls who come up to me in the street in tears and say: 'When's the Sex and the City movie happening?'.

"If you look at The Devil Wears Prada, it was such a big success, this would do even better.

"Sex and the City has the audience and I think it's a good time to do it now because enough time has passed since the TV series ended."

Australian Sex and the City fans can win a $US10,000 ($A13,000) trip to New York and live the lifestyle of Carrie Bradshaw by watching episodes of the show on Foxtel's W channel.

At 8pm each day until March 2, the W channel is screening "the most romantic" Sex and the City episodes. Viewers can win the trip by playing an interactive trivia game with their Foxtel remote control.

The winners of the New York trip will receive two return flights from Australia, seven nights in a Manhattan hotel and $A2,000 spending money.
