"Let's see when she becomes governor, we can talk about how all that will work," Star said. "You know, don't governors get hiatuses or something?... Sort of take a break from governing the great state of New York and do a movie? You never know!"
As for the option of recasting Cattrall's role, Star claims that "It's nothing I've thought about right now seriously."
"I mean, for right now, it's like, I loved the series and those first two movies," he said.
Since the show went off the air in 2004 and its two subsequent film sequels in 2008 and 2010, there's been no shortage of off-screen drama between the cast, which also includes Sarah Jessica Parker and Kristin Davis.

'Sex and the City' Turns 20! (Flashback)
In November 2017, Cattrall, 61, told Piers Morgan that "[The cast has] never been friends. We‘ve been colleagues and in some ways, it’s a very healthy place to be because then you have a clear line between your professional life and relationship and your personal."
Parker, 53, confirmed to ET that a third movie was off the table in January. "I struggle with it because it's a bit sad, but I think one must keep these things in perspective. I have a lot of incredible memories, singular memories, that are shared among those four women, and I'm incredibly grateful for the experience... I forever love having had that time with those women," she said at the time.
"I found it very upsetting because that’s not the way I recall our experience. It’s sad, but I always think that what ties us together was this singular experience," Parker told host Andy Cohen. "It was a professional experience but it became personal because it was years and years of our lives, so I hope that that eclipses anything that’s been recently spoken.”
After Nixon announced her gubernatorial bid in March, ET caught up with the 52-year-old to talk about the third film's cancellation and how it affected her decision to run.
"Not at all," Nixon replied when ET asked if SATC 3 getting shelved was "the final" push to encourage her to run. "... This is a decision that has been a long time coming. People have actually been asking me to do this for nine years."
