Continuity mistake: Samantha and Carrie are hanging Carrie's poster in her apartment. In one shot, the whole poster is pinned to the wall and in the next shot, the bottom left part of the poster is curling up. After another shot of Samantha, the poster is pinned perfectly to the wall again.
Revealing mistake: When Carrie bumps into Mr. Big and her purse falls, watch the people in the background carefully. Many of them are watching the couple talk and interact with each other. On a busy New York street nobody is going to pay attention to two people having a conversation. Apparently all these people were watching the shooting of the scene.
Continuity mistake: Carrie and her friends are in the City, waiting for the bus with her photo on it to drive by. When it does, there is a shocking hand-drawn image of a sexual nature near her head on the poster. In the next shot of this image, which is more of a close-up; it's a different drawing. Very similar, but obviously not the same drawing as shown the first time. (00:19:00)
Continuity mistake: Carrie is in the hotel bed from her night with the French Architect, who is just leaving for the Airport. There is a shot of the small table by the bed, with the phone sitting on it. You cannot see any envelope at all resting against the phone, or visible at all. But with the next close-up, suddenly there is a large business-size envelope with her name on it resting prominently against the front of the phone. This envelope was not there previously. (00:14:45)
Continuity mistake: After Amelita buys Carrie the shoes and Carrie turns to walk out, Amelita is standing right behind her still talking yet when the shot changes to Carrie walking out the door, although we can still hear Amelita chattering, she's no longer standing there or anywhere in sight.
Continuity mistake: During the scene when Carrie and Sam are in the changing booth at the clothing store, Carrie starts helping Sam take his shirt off. She pulls the outer plaid shirt down quite a bit, revealing his white undershirt. But in the next shot of him, Sam suddenly has the plaid shirt back up around his neck. Then in his next shot, it's back down and the white undershirt is showing again.
Continuity mistake: When Big arrives at the party Carrie is eating a snack, with a remaining one on her hand. Big sees her and she's eating another snack, which leaves her with zero food. Half a second later there's a wide shot and not only is she not chewing the previous bite, but 2 snacks have suddenly appeared on her hand.Sacha
Visible crew/equipment: When Stanford and Carrie walk backstage with the models, check the reflection on the glass and you'll see: the boom mic operator, camera and, best of all, a group of technicians crouching on the floor, failing to hide and moving around when Carrie and Stanford walk around.Sacha
Continuity mistake: Before dinner, Miranda holds the candles with her right hand. Then puts them in her left hand. A nanosecond later, from a different angle. She is leaving them on the table using her right hand. She couldn't have used her left hand for she is holding the napkins and they would've fallen down.Sacha
