‘And Just Like That’ star says show has given him financial security in his ‘third act’

And just like that … he’s in his “third act.”

Mario Cantone — who has played Anthony Marentino in the “Sex and the City” franchise for 24 years — is grateful to have a steady job late in his career.

“I’m the luckiest boy in the world,” the 64-year-old actor told Page Six Monday at the Only Make Believe’s annual gala.

He added, “I work with the best people. I feel very safe with them, it’s comfortable, joyful.”

The comedian, who referred to the HBO spin-off “And Just Like That…” as his “third act,” said working on the show has been a “gift.”

Cantone noted that he only starred in 12 episodes in the original run of “Sex and the City” before becoming a regular on the show’s reboot, which recently wrapped its third season.

He also appeared in the “Sex and the City” movies, with his wedding to Stanford Blatch (Willie Garson) opening the second film.

Cantone admitted that before signing on for the HBO Max series he worried about retirement funds but doesn’t have to now which is “really, really great.”

“We’re theater people, we go from job to job, we’re television people,” he shared, “yeah, this came at the right time.”

Catone also shared that this unexpected paycheck came at the right time because if it had come “when I was younger, I’d blow it all, blow it all! My mother used to say, ‘You can’t hold onto a dollar!'”

“The View” regular said he would have blown it “on either high-end travel or high-end hotels, that’s what I spend my money on.”

Cantone was joined by Rachel Dratch, Lena Hall, Brian Stokes Mitchell and Montego Glover at the gala Monday, which raised over $800,000 that goes towards creating interactive theatre with children in special education schools, hospitals and care facilities.
