Deliberate mistake: The second time they show Samantha having sex on her 'rolling bed', you can see that the guy is too far above her to actually be having sex with her. They are too far apart, probably to make it less awkward for the actors. (00:12:05)
Sex and the City (1998)
4 mistakes in Frenemies - chronological order
Starring: Sarah Jessica Parker, Kim Cattrall, Kristin Davis, Cynthia Nixon
Samantha: There isn't enough wall space in New York City to hang all of my exes. Let me tell you, a lot of them were hung.
Trivia: Carrie is the only main character who never appears nude (she is either dressed or covered by something). Sarah Jessica Parker had a strict "no nudity" clause in her contract.
Question: During the first few seasons (pretty obviously in season 3), Carrie often wears the same ring on her right or left hand on her middle finger. Is this Sarah Jessica Parker's wedding ring?
Answer: Yes, it is.
