Kim Cattrall Discusses the Possibility of 'Sex and the City 3'

Kim Cattrall opens up about becoming Samantha Jones again.

— -- Kim Cattrall looks back on her time as Samantha Jones on "Sex and the City" as "a Valentine experience."

So, the opportunity to step back into the character's stilettos for a third movie would be an opportunity she'd welcome.

"Occasionally I’m at someone’s house or I'm flipping through the channels and I come upon the scene [in the show] and it makes me feel so good. I think the show stands up and I'm so proud of it," she told ABC News. "I'd love to come back, but it’s a very high bar and we’d need to get everybody back there and scheduling is difficult for people’s lives but always! I revisit it all the time."

So much so that Samantha, a take-charge woman for whom no topic was off-limits, inspired Cattrall in part to be a voice for women too. So, the actress, 58, has partnered with Pfizer for a new campaign, Tune In To Menopause, and is encouraging women to "tune in" to their bodies and embrace the changes that occur as a result of menopause.

Kim Cattrall: What Happened to Sex and the City's Samantha Jones?

"This is nothing to be ashamed of," she said. "This is something to look at and realize, 'I'm lucky enough to go through this because I'm still alive!' Life is really about change.'"

For Cattrall, that change occurred a few years ago, when she first felt a hot flash. It was, she said, "like someone put me in a vat of boiling water." Disoriented, she immediately called her gynecologist.

"Everybody's menopause is different and everybody needs to investigate [hers] with a physician because it's challenging," she said. "[My doctor] said what I was going through was normal and started a journey for me... to make my menopause manageable."

Now, it is, leaving Cattrall to focus on other aspects of living well. The actress, who will appear in a documentary series, "My Shakespeare," on PBS later this year, said that she sticks to a healthy diet and gets plenty of exercise in an effort to stay in shape.

"It really starts with caring about myself," she said. "I'm choosing work that I really want to do and I think that shows too. It's not just skin-deep! I'm happy."
