Corrected entry: When arriving to Mexico, Carrie is lying on the bed with the light streaming in the window and Samantha comments "It's going to be a gorgeous sunset." Next day morning Miranda wakes her up with word "Morning" and the sun is still shining on the bed from the same side. (00:56:40 - 00:57:25)
Corrected entry: When Charlotte leaves the house in Mexico to go to the gym, she is wearing black work-out pants and a pink tube top. When she leaves the spa, she's wearing pink pants and a dark purple top. The blue bag she's carrying isn't bulky enough to be full of a change of clothes, as you can see when she rushes past the girls back at the house.
Corrected entry: In the last season of the show, Samantha declares she is 45. In the movie, which is set three years later, she celebrates her 50th birthday, and the story of the movie spans a year; she should have been celebrating her 49th birthday.
Corrected entry: Carrie dyes her hair a deep brown colour after leaving Big, but towards the end of the movie, she is back to her original multi-coloured, unkempt hair, which is the same as the start of the movie. It is almost impossible to go back after a dye job to a previous colour, especially one like Carrie's.
Corrected entry: In the first half of the movie, Carrie had blonde highlights with some roots showing. When Carrie comes back from her "honeymoon" with the girls she dyes her hair a dark brown. Then, toward the end of the movie, Carrie visits Charlotte in the hospital after she has her baby she has highlighted hair with some roots as she did in the first half of the movie.
Corrected entry: Charlotte's water breaks when she is standing on the sidewalk; for one thing, there is no sound of water hitting the ground and secondly, there is no wet patch on the ground when the shot zooms out moments later.
Corrected entry: Throughout the entirety of the film, at least eight boom mikes appear during the course of it.
Corrected entry: Right after the wedding fiasco, Samantha tries to cancel Carrie's honeymoon trip for her. She tells Carrie, Charlotte, and Miranda that she couldn't get Carrie a refund, but she instead got them all in (meaning the girls are now going to Mexico), and she has booked three more seats. However, there were already two seats booked (for Carrie and Big), so Samantha would only need to book two additional seats to accommodate all four of the girls.
