Last night I happened to watch the interview Kim Cattrall gave to Piers Morgan in October 2017. He cleverly saved the SJ Parker controversy for (near) the ending, and Kim was quite expressive in both ways. She indeed assured they were never friends but colleagues (not even in the first 2 years, though some people blame Darren Starr leaving for the initial problems), and explained everything concerning the show and its two movie sequels.
When they changed the subject (eventually), I got the impression that it was Kim who was resented for the lack of contact from her SATC pals previously to the rumors about this third (and canceled) movie, as if saying,"well you b*tches only call me when you have a SATC project in works but don´t even call me for wishing me a Merry Christmas". I think it might have been a case of wrong PR because it seemed that people (producers?) had contacted her to ask her ONLY about this third reunion.
I must say that I had never seen or heard the actress being interviewed (aside from some shallow SATC promos) and it was a nice surprise, not only because of her honesty when she talked about her humble origins but also because of her accent and her overall coherent talk.
Maybe she is a truly amazing actress (I haven´t seen much of her out of SATC) but I almost believed her (99%). What I can´t assure is if Kim herself wrote those Instagram messages because it doesn´t sound as the same Kim of the PM show. Not to deny that, at some point, he tried to get "a bit more" re SJ Parker, but he failed. Kim´s smile was priceless though.
In reality it all sums up to that quote: "Now I´m 61 years old, I want to be the one who decides what to do with my life". I though that was an amazing thought.
