Revealing mistake: In the scene where Big and Carrie meet in their cars after Big fled the wedding you can see down the street in the distance a huge amount of SATC fans have gathered to watch the filming. (00:52:35)
Continuity mistake: When Miranda takes a sip of her latte in the restaurant scene with Steve, only half of her upper lip has foam on it. In the next shot of her it is covering the whole of her upper lip. The same happens to the foam on Steve's lip when he mimics her. (00:24:50)
Continuity mistake: When Carrie is feeling depressed in Mexico and is being fed food in bed by Samantha, there is a tea pot on the tray on the bed. The scene changes back and forth between Samantha and Carrie and each time it changes, the style of the tea pot completely changes. When it's a shot of Samantha, it's a regular tea pot with a lid, and when it's a shot of Carrie, it changes to an art deco style pot with no lid whatsoever.
Continuity mistake: In the scene where Carrie and Big are in bed (Carrie is reading the Love Letters) the library card Carrie uses as a bookmark keeps changing position. She opens the book and holds the card behind the book cover, then when you see a close-up of the text you can see the card is being held inside the book. Then it's back behind the book cover. (00:22:25)
Continuity mistake: When Carrie announces her engagement, Charlotte screams then jumps up from her chair and a white cloth napkin suddenly appears in Charlotte's left hand, only to disappear and reappear. (00:12:35)
Continuity mistake: When Charlotte, Anthony and Carrie are planning the wedding, Carrie has a pen attached to her dress strap which keeps changing positions (it doesn't disappear, we can still see its black cap) while she is sitting on the bed and when she gets her wedding dress out of the closet. (00:16:00)
Continuity mistake: Early in the movie when Carrie, Miranda and Charlotte are having lunch and Carrie is about to tell them that she and Mr.Big have decided to get married - Miranda's fork moves from one hand to another between shots whenever the camera angle changes. (00:14:00)
Continuity mistake: When Charlotte places the three Post-It notes on the doorway, their positions keep changing back and forth in the following shots. (00:31:35)
Continuity mistake: When Louise calls Carrie from the bridal salon, her little sister is visible in the mirror's reflection as she holds Louise's Louis Vuitton bag on her lap. In the reflection the back of the Louis Vuitton bag faces out, but in the sister's close-up the bag's distinctive front faces out, then in the next shot it's the back again. (02:09:30)
Continuity mistake: During Carrie's personal assistant interview with the Asian man, in the shot facing Carrie her papers and coffee cup are centered on the table in front of her, but as the camera pans down to the man's pink high heels the items are at the corner of the table.
Continuity mistake: At the Italian restaurant, when Miranda explains that she has a brief to work on at home, Magda lifts her glass of water with her left hand, but in the shot facing her she holds it in her right hand, then it's back in her left hand again. (00:23:35)
Continuity mistake: The bread lies perpendicular to the chopping board but a shot later it's parallel to it. (00:32:53)
Revealing mistake: When the girls arrive at the wedding, a group of fans on the upper left corner are gathered watching the filming.
Visible crew/equipment: After the wedding, when Big and Carrie's car cross, a big, long rectangular black structure in the middle of the road is reflected on Big's car. Most surely where the camera and team were.
Visible crew/equipment: During the Take or Toss scene, a rectangular black object is reflected on the champagne bottle, which is definitely not Carrie nor the closet. Most seemingly the filming camera. (00:31:44)
Revealing mistake: Carrie is flipping through her book's pages. In chapter 14 the lines "Upper East Side neighborhood" are repeated over and over again.
Visible crew/equipment: When the girls greet each other, a filming light is reflected on the revolving door behind them. (00:07:49)
