Continuity mistake: When Carrie meets the doctor there's a couch right behind them, plus a table next to him and another couch behind Carrie. A shot later they're surrounded by people despite the place being packed with stuff a second ago.Sacha
Revealing mistake: Just after Big has left NY for good, Carrie leaves his apartment and is walking down the street. A leaf (that another mistake pointed out was digital as it was falling to the ground) is lying on the sidewalk. Carrie picks it up, but it is obviously an artificial one made from plastic and fabric.raywest
Visible crew/equipment: When Charlotte leaves her apartment building on the way to the party, she puts on large sunglasses. You can see what appears to be camera equipment, in the reflection of the plastic lenses. There are two white squares, which look like a camera light and filter screen. (00:22:20)
Continuity mistake: When the horse drawn buggy is pulling over to the curb in front of the hospital, you can see it dodging traffic and cars. But after Carrie leaves and the buggy pulls away with only Mr. Big, suddenly there are no cars or traffic in sight. The entire street from that direction appears to be completely empty. (00:22:50)
Character mistake: Miranda, Charlotte and Carrie are sitting in the cafe waiting for Samantha, when she runs in late, armed with her photos. Just before she'd arrived, a waitress had come to take their order - Carrie ordered a drink but nobody ordered food, but when Samantha offers the photos to look at Miranda says something like "But only till the food arrives." They didn't order any food.
