Continuity mistake: In the scene where Carrie and Miranda are eating cakes outside the shop, talking about Miranda having to be supportive to Steve about his basketball competition, keep an eye on Miranda's cake. She takes bites out of the cake and then when it is down to the last bite, the camera shows Carrie, then shows Miranda again with the cake suddenly full.
Continuity mistake: The episode 'Attack of the 5 foot 10 woman' in season three, when Charlotte is afraid of the sauna. She is running into the sauna with a towel wrapped around her waist. The towel comes loose and is nearly falling off - but in the next shot it is neatly tied around her waist.
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: When Carrie and Shaun are laying on the floor of her bedroom, she has her left hand resting on her chest. But in the very next shot; her left arm is laying across her stomach, and her left hand is curved around her right waist. No time has passed in between these shots. (00:12:25)
Continuity mistake: During this scene when Samantha is confronting her new assistant, the office set-up is completely different than before, when Nina G. was working for her. The assistant office space is much larger, glass desk, different angle, next to small conference room instead of Samantha's office, etc.; obviously not the same office set as previously used. Yet Samantha has not changed offices at all during this time period, as it wasn't too long ago when she fired Nina G. Something as major as changing offices would definitely have been mentioned in the plot (as changing apartments always is); and there hasn't been enough time since she fired Nina G. (00:13:45)
Continuity mistake: When Carrie is in Big's kitchen, and hears Natasha come home, she tries to leave in a hurry. She puts on her blue levi jacket, so it's about halfway on with her left arm in the sleeve. But in the next shot of her, Carrie is suddenly wearing only her pink bra and carrying the blue jacket. As she unlocks the door and starts running down the stairs, she throws on the blue levi jacket for the second time. (00:25:15)
Continuity mistake: When Carrie is lying on her bed, she is wearing yellow pants over a green top. The top portion of her pants is unbuttoned/unzipped as she moves. But after she picks up the phone to call Big, she is sitting up on her bed, and her pants are suddenly buttoned/zipped completely up. There was no opportunity in this sequence for her to have closed her pants. (00:12:15)
