Over the course of her career, Betty Buckley has managed to slip between stage and the silver screen and the small screen with deceptively graceful ease.

On TV, she played the stepmom in "Eight is Enough," starting a string of roles on very different shows, including HBO's "The Leftovers" and "Oz."

On film, she portrayed the kindly gym teacher in the movie version of "Carrie" (and, much later, she was the crazy mom in the stage musical adaptation of the same story). Buckley's latest movie, M. Night Shyamalan's "Split" with James McAvoy, comes out in January 2017.

But stage is where Buckley shines the brightest. As Grizabella in "Cats," she turned "Memory" into a spine-tingling showstopper — and won a Tony award for the performance. She got into the "All right, Mr. DeMille, I'm ready for my close-up" delusions of fading movie star Norma Desmond in the musical version of "Sunset Boulevard" in London and on Broadway.

Knowing all that, it's clear that seeing a performer of Buckley's caliber in concert at a venue as intimate as the Katharine Hepburn Cultural Arts Center is bound to be An Experience. She will, in fact, be there Saturday night, when you can hear the woman who was called "The Voice of Broadway" by New York magazine.

Betty Buckley, 8 p.m. Saturday, Katharine Hepburn Cultural Arts Center, 300 Main St., Old Saybrook; $67-$75; 1-877-503-1286.
