Check out this New York Times video about the Sex and the City premiere, in which Sarah Jessica Parker is asked, "So what do you say to all the would-be Carrie Bradshaws?"
"I'd say stop at the library on the way to get the purse."
SJP seems to take her own advice. She discussed the Victorian novel New Grub Street by George Gissing in an interview with New York magazine, and her son, James Wilkie, is named after Wilkie Collins. By the way, if you haven't read Wilkie Collins' The Moonstone (which T. S. Eliot called "the first and greatest English detective novel") I recommend it as one of those classics which is actually fun to read. It's set in the 1800s and revolves around the mysterious disappearance of a precious diamond hours after it reaches a country mansion.
