“We don’t [know],” Parker laughed in reference to when a third big-screen production of SATC might hit theaters. “But if you do, please do let me know!”

MTV After Hours host Josh Horowitz then introduced “leaked” pages from the top secret script, asking Kinnear to play a man named Rex and Parker to play Carrie, while he read for Kim Cattrall’s Samantha.

The faux script sees pals Miranda and Charlotte caught in a “time vortex,” which brings them to the old west. While Parker seemed to find the pages hilarious, Kinnear appeared less than thrilled to partake in the group’s shenanigans.

The CW recently green-lit a highly publicized SATC prequel, titled The Carrie Diaries. Back in May, Parker gave a tentative stamp of approval on the still-rumored project.

“I think it always comes down to story and what is the story people want to tell,” she told MTV. “Obviously I feel proprietary in the best possible way about that entire franchise as it were, but I think there are lots of talented storytellers and obviously lots of talented actors who might be a part of it. I think, like anything, you base your opinion on material and content, and I think that would be the only way for any of us to have an opinion. “

HBO owns the rights to the series, with corporate cousin the CW hearing the pitch Friday, Sept. 9, and committing to the project immediately afterward. If it goes to series, the project would fit into a CW lineup that already includes such young- and female-skewing fare as The Vampire Diaries, Gossip Girl and 90210.

The project hails from Warner Bros. Television and Josh Schwartz and Stephanie Savage’s Fake Empire, with former Sex and the City scribe/co-producer Amy B. Harris attached to adapt and serve as showrunner. Fake Empire's Len Goldstein also is attached as an executive producer.

The first book in Candace Bushnell’s origin story was published last year and, like Sex and the City, is told from Carrie’s point of view. It follows the aspiring writer through her relationship with Sebastian Kydd and rivalry with popular girl Donna LaDonna during her senior year of high school in the early 1980s.
