The medicine cabinet in Carrie's apartment was first spied by Sarah Jessica Parker at a flea market shortly before filming began on the series. She and Matthew Broderick didn't buy it, but reconsidered. When they went back, the cabinet was already sold to "some television show". When she showed up for filming, the medicine cabinet was there.
Sarah Jessica Parker had a clause in her contract for this show stipulating that she will not do any full nudity. This is why the audience never sees Carrie in anything less than underwear, whereas all the other main female characters have been filmed in much less.
"Jules & Mimi", the bi-racial sexually charged BBC series that Miranda recorded and watched religiously on her TiVo, is not a real show. Paul Lee, CEO of BBC America, quipped to Jack Myers Report, "We should commission Jules & Mimi. It would be the first time a scene in a sitcom has inspired another show."
Although Carrie says her address is 245 E. 73rd Street in Manhattan, the actual exterior of her iconic brownstone apartment is 64 Perry Street in the West Village. You can visit the apartment, but a chain blocks people from going up the steps, as it is a private residence.
From the first season up to the twelfth episode of the fourth season, in the opening credits, Sarah Jessica Parker's name was shown with the World Trade Center towers behind her name. After the terrorist attacks on the U.S. of September 11, 2001 and the collapse of the towers, her name then appeared with the Empire State Building in the background. The same thing happened with the show's main title.
The part which ultimately went to Matthew McConaughey in season three, episode thirteen, "Escape From New York",was originally written for Alec Baldwin, who declined. The producers then contacted George Clooney who, although was interested in it, couldn't do it. The script was then sent to Warren Beatty, who also declined.
Showrunner Michael Patrick King admitted that one of the main reasons behind the love story between Carrie and Aleksandr Petrovsky is that he was sick of the fans complaining of how Mr. Big was older than Carrie, so he decided to pair her up with a real older guy.
The exterior used for Carrie's apartment at 64 Perry Street, which is a four thousand square foot, five bedroom townhouse, was sold to anonymous buyers in 2012, and again in 2013 for 9.85 million dollars and 13.25 million dollars respectively.
Samantha is the only one of the four leads to never have a family member make any kind of appearance in the series. Family members of Charlotte and Miranda appeared, and Carrie's father is shown once in photographic form.
One of the guests at Lanie's baby shower in Season 1, Ep 10 (woman eating a piece of cake, describing how she used to run a company but now just yells at the gardener) also plays another/different character in Season 2, Ep. 13 - Carrie's therapist, Dr. G.
This show is often called Sex in the City. However, people may be confusing Sex and the City with another similarly titled show Caroline in the City. Both shows feature female lead characters. Both shows aired in the 90s, though Caroline in the City ended in 1999.
Michael Patrick King, during a commentary of the third season, stated the reason he did not want to bring much of the four main characters' families into the show, was to maintain the focus being centralized on the four leads. In fact, when Charlotte gets married the first time, her father's face is barely even shown as he walks her down the aisle.
