The hit series, which starred Sarah Jessica Parker, Cynthia Nixon, Kristen Davis and Kim Cattrall, ran on HBO from 1998 to 2004 and has since spawned two feature films.
Noth, who played Parker's love interest Mr Big, told Parade: "I miss the early days before it became sort of a circus of attention, when it hadn't become this iconic thing. It was just really good writing and entertainment, and then it became something else that I still don't really get.
"It actually got to the point with the movies that we had to make up plotlines so that people wouldn't know what we were doing and expose it and it be all over the papers. That was pretty crazy. You used to be able to go under the radar and have fun."
Noth added that he has no opinion on whether or not the Sex and the City franchise will get a third film, adding: "Well, it's not really in my hands, but from what I can tell, I don't see it happening. But what do I know? I'm always pleasantly surprised if they do one, and I'm not disappointed if they don't."
Cattrall has also expressed scepticism over a third movie, admitting that she is unsure if she would reprise her role as Samantha Jones if the project came to pass.
Davis has also objected to a follow-up if the reboot were to take the form of a series prequel.
