Sarah Jessica Parker wants to play Carrie Bradshaw in a possible 'Sex And The City' prequel.

The 45-year-old actress insists advances in video technology would make it possible to play the journalist as a teenager, as depicted in creator Candace Bushnell's latest book 'The Carrie Diaries'.

She told E! Online: "Who do I want to play teenage Carrie? I don't know.

"Maybe they should use old footage of me. And in this new age of 'Avatar', what about a new 17-year-old S.J.?"

In the early 80s, Sarah Jessica was starring as Patty Greene in US TV series 'Square Pegs' and insists the character was a good representative of the early Carrie.

She joked: "That might have been Carrie in high school."

The actress - who has seven-year-old son James Wilkie and 11-month-old twins Marion and Tabitha with husband Matthew Broderick - recently admitted she plans to take her eldest child to see 'Sex and the City 2', but will take him out of the cinema during the raunchier moments.

She said: "If I can manage to take him out for popcorn for two certain moments, I think he's ready for it. He has too many questions, and he's too clever for us to keep it from him.

"I wouldn't say this movie is for seven-year-olds, but we'll find a way of figuring it out."
