“I have had a massive meander in my life,” Jessie Buckley says. The Irish actress, 28, is sitting in a booth at the Ace Hotel here, preparing to head to the set of “Judy,” which she’s shooting alongside Renée Zellweger. “I quite enjoy the meander,” she adds. “There’s so much that’s there to explore and have an adventure with.”

Buckley got her start in theater, doing everything from musicals to Shakespeare, and had a jazz singing career for several years in London before being cast as Marya Bolkonskaya in the 2016 miniseries “War & Peace.” Since then, the actress appeared in FX’s “Taboo” and shot several upcoming TV series and films, including a BBC adaptation of “The Woman In White” and “The Voyage of Doctor Dolittle” (in which she portrays Queen Victoria opposite Robert Downey Jr. as the title character) [ . . . ]
