The series originated from a script for a third Sex and the City film that had been approved, but Sarah Jessica Parker confirmed in 2017 that the movie would not happen despite it being described as 'beautiful, funny, heartbreaking, joyful, very relatable.'

The shelved third film's script was later redeveloped into the miniseries revival that became And Just Like That..., with Kim Cattrall's Samantha excluded in line with her earlier statements that she did not want to return to the franchise.

It was reported that the abandoned third film would have involved killing off Mr. Big and had Samantha receiving sexting and nude pictures from Miranda's 14-year-old son Brady, storylines Kim Cattrall reportedly disagreed with.

Long-time Sex and the City costume designer Patricia Field did not return for the revival, but she recommended her friend and colleague Molly Rogers to consult on the costumes.

Willie Garson, reprising his role as Stanford Blatch, died on September 21, 2021, only three months after joining the cast and after filming his scenes for the first three episodes; the show explained his character's absence through a letter to Carrie in episode four.

Despite Mr. Big dying in the first episode, Chris Noth had been set to appear in a fantasy sequence in the season finale, but his scenes were edited out after sexual assault allegations were brought against him.

Kim Cattrall returned as Samantha Jones for a brief cameo in the season 2 finale despite her long-running public feud with Sarah Jessica Parker.

To mislead speculation about the major plot twist of his character's death, Chris Noth arrived on set on the very day his character's funeral scene was being filmed.

After the peloton bike workout scene leading to Mr. Big's death aired, Peloton's stock dropped significantly, prompting the company to issue a statement clarifying it had agreed to product placement but was unaware of how the scene would use it, and pointing to the character's cigars and steak consumption as contributing factors instead.

Three days after the death episode aired, Peloton released an ad featuring Chris Noth and narrated by Ryan Reynolds ending with the line 'He's alive,' but the ad was pulled four days later after sexual assault allegations against Noth were reported.
