Kim Cattrall -

It's no secret that there has always been bad blood between Kim Cattrall and her 'Sex and the City' co-star, Sarah Jessica Parker. The two worked together for decades despite their contentious relationship, portraying the best of friends on our screens, but when it came time for the reboot, Kim Cattrall said no. In fact, she had already said no to any further 'Sex and the City' projects back in 2017. A third SATC movie was set to be made, but production was reportedly canceled due to Kim Cattrall pulling out. 

With the release of the SATC sequel 'And Just Like That...' fans wondered if Cattrall would make an appearance. It seems like she got her wish to be written out of the show, as the first episode explains that Samantha moved to London after a dispute with Carrie, played by Sarah Jessica Parker. This seemed to tie up Samantha's storyline, but she reappears in the form of a text exchange with Carrie in episode five. The two have a witty exchange, but when Carrie says "I miss you," Samantha doesn't reply... The writers really seem to be mirroring the feelings of their fans!

This spooky repetition of history is, however, without the whispers of drama on set, and Mantock called her time on the show "an immense privilege" in a statement, and added that it was a "difficult decision to leave," People reports.
