Continuity mistake: When Samantha is in the waiting room to get her results for the AIDS test; the wide shot shows two women seated in the orange chairs on the left. One of them has a pony tail and glasses. A man with dark hair is also seated in the chairs on the right. But when we see the waiting room again right before Samantha faints; only one woman is seated in the orange chairs on the left, and the woman with the pony tail and glasses has moved down, and over to the far yellow chairs on the left. There is also a second man in a blue shirt seated closer to Samantha, in the chairs on the right. This entire scene occurred in seconds; and there was no time for anyone to have gotten up, sat down or moved locations. (00:18:50)
Revealing mistake: When Samantha and her partner are using the 'swing,' you can tell from the long shot that Kim Cattrall is actually wearing some sort of prosthetic around her hips, to simulate her rear area. It is larger, and sticks out prominently in an unnatural manner. This was probably done to ensure modesty for the actress. (00:22:30)
Revealing mistake: When the gardener hands Charlotte the rose, he is supposedly picking it out of some rose bushes he is in the process of planting. He even makes a motion as if 'picking' it from the bunch. But when he hands the single long stem rose to Charlotte; it's obvious that this rose has already been cut, and is missing the lower leaves. (00:16:05)
Continuity mistake: When Carrie and Mr. Big are having their affair in the 3rd hotel; it is located on 56th & 8th, and is described as being a 'seedy location'. When you see the inside of the hotel room, it is obviously a very cheap, tacky hotel. But later in the episode when Carrie and Mr. Big are in the lobby of this same hotel on 56th & 8th (verified in voice over); it is obviously the lobby of a much nicer, elegant, more expensive hotel. (00:02:05 - 00:19:30)
Continuity mistake: When Carrie and Aiden are arguing out on the street in front of her apartment, there is a shot of her holding the leash for Pete the dog in both hands. But suddenly as she is yelling at Aiden, you can see her throw both her hands up in the air and touch her head. She is not holding the leash at all. Then seconds later; there is a shot of her legs as Pete is running off, dragging the leash from her body and waist as if she is still holding it. (00:24:30)
Character mistake: When Carrie is describing the younger guy she is dating, she claims he is the creator of an Internet magazine 'that she still wasn't able to find on her computer'; meaning she had searched the Internet for it. But as we learn later in the series, right before she gets back together with Aidan for the second time; she doesn't have the Internet on her computer until then. The girls talk her into getting it, in order to email Aidan. So there was no way she could have searched for the other guy's Internet magazine on her computer, as it was an older Mac laptop and not likely to have search engines without Internet access. She was only using the hard drive at that time.
