Continuity mistake: When Carrie is startled by the squirrel and tosses the pie crust onto the counter, the camera cuts to her clasping her legs where she burnt them. In the next shot of the counter the pie crust has vanished; then in the next shot of it, the crust has returned. Also, the tray and tea towels change positions.
Continuity mistake: In the episode where Big returns from Paris, Carrie meets him at his apartment with a beret and 2 McDonalds bags. She says she got a Big Mac and a Filet O'Fish. She asks him which one he wants, holding the Big Mac in her left hand and the Filet O'Fish in her right. Instantly the sandwiches switch hands in the next shot as Big walks to the right.
Other mistake: When Carrie, Samantha and Miranda step outside of the hotel so Carrie can have a cigarette, she takes a couple of draws then throws it down on the step. She tries to stub it out with her shoe by twisting her foot on it but she (the actress) accidentally kicks the cigarette down the step, so she has to just pretend to still be stubbing it out.
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.
The big time - S3-E8
Continuity mistake: In the scene where Miranda is woken up by the dog barking and finds that Steve hasn't come back to the apartment that night, the puppy she picks up is older than the puppy Steve picks up when he comes back to the apartment the next morning.
Continuity mistake: At the bar "Trade" Charlotte is having tape on her upper body in one shot, but it disappears a second later when she sees Anthony. She has no time to take it off. (00:03:45)
Audio problem: When Samantha and Carrie are in their room on the train, Samantha starts to pour herself a glass of champagne. We hear it pouring for a few seconds until it sounds like the glass is full but when she puts the bottle down, there's barely anything in her glass.
Continuity mistake: In the restaurant with Big and Carrie, Big's either holding the stem of his wine glass, or holding it above the stem between shots. There isn't any time for him to switch the position of his hand between shots.
Attack of the five foot ten woman - S3-E3
Continuity mistake: When Magda opens Miranda's 'goody drawer' Miranda quickly slams it shut it with her hip. In the next shot, it is still open a little way.
An american girl in paris (part deux) - S6-E20
Continuity mistake: While in the salon's changing room, Samantha takes off her black 'cape' twice.
Don't ask, don't tell - S3-E12
Factual error: I live in Edinburgh and Caleb's accent is way off. Nobody from Scotland speaks like that, especially not Edinburgh where the accent is mild.
Continuity mistake: When Charlotte and Carrie are sitting at a table outside, there is a woman with a long brown leather coat walking by. Shortly afterwards the same woman with the long brown leather coat walks by again. (00:08:20)
Cover girl - S5-E4
Revealing mistake: When Samantha walks in on Marcus 'servicing' Stanford, the positioning is all wrong. Marcus' head is too high up to be realistic for what is happening. His head is almost up to the level of Stanford's chest. (00:21:20)
Continuity mistake: When Samantha and her date are in the health food restaurant, she orders wheatgrass shots. The waiter pours them, filling the cups to the brim and then sets one on the table in front of each of them and we see again in a close up that they are both full up. Yet when Samantha picks up hers to drink, the liquid level has gone down a little way.
Continuity mistake: There's a scene that opens with Carrie and her boyfriend in his apartment, and he's sitting with baby Brady on his lap. The camera cuts to another angle, and it's very obviously a different baby.
Continuity mistake: When Carrie knocks the vase of carnations off the table, the flowers scatter all over the room, but in the close up shot of the table, there are still a bunch on the table, and on the floor around the base.
Ghost town - S4-E5
Continuity mistake: Carrie, Samantha and Miranda are at the opening of Steve and Aidan's bar. Carrie lifts her hair off her neck with her right arm, but then in the next shot, she is lowering her left arm.
Continuity mistake: At the end of the show, when Carrie visits Jeremy at the psychiatric facility, they are sitting outside having a picnic. As they are talking, notice Carrie's necklace. It is a bolero-type necklace and the red stones on the end move up the necklace to near the clasp and then back down into her cleavage. Then they go back up again.
Cover girl - S5-E4
Continuity mistake: Carrie goes inside the changing booth to try on the pink outfit. Then after Stanford and Marcus arrive, Carrie suddenly whips the curtain open to reveal herself completely changed into the new outfit including shoes, after only 21 seconds. These events happen in real time; and there is no logical way that Carrie could have changed from one complete outfit to another in that time. (00:17:45)
Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
