The new trailer for “The Carrie Diaries,” starring AnnaSophia Robb as the young Carrie Bradshaw, is out and it’s the fun froth you would expect. You’ve got to hand it to the “Sex & The City” franchise: they sure are dedicated to fantasy! We’re not sure how many suburban girls fresh off the boat from Connecticut get scooped up immediately by the fashion editor at Interview magazine, who sends Carrie free clothes and trots her out to the hottest club. The ’80s fashion is fun, though, and AnnaSophia really has got Sarah Jessica Parker’s facial movements down. Clearly I will be watching this (although I’d never admit it) when it debuts in January.
