Kieran Culkin Could Rule Oscar Season. He’d Rather Be at Home. Kieran Culkin Could Rule Oscar Season. He’d Rather Be at Home.

The “Succession” actor is an awards front-runner for “A Real Pain,” but his actual priority is being a dad: “That’s the whole point of life.”

One of the many eccentricities of a modern-day awards campaign is that it can last much longer than the film shoot that put you in contention in the first place. In 2010, I spoke with Mark Ruffalo partway through a monthslong awards campaign for “The Kids Are All Right” and he said, with some astonishment, “Kyle, I spent six days on this movie.”

Still, most actors are happy to decamp to Los Angeles and stump for their film for several months. (It worked out pretty well for Ruffalo and his movie, since both were Oscar-nominated.) And that’s why I’ve recently seen a lot of Kieran Culkin, who’s considered the supporting actor front-runner for “A Real Pain”: To tout the movie, he wooed film critics at an intimate dinner at Spago, worked the ballroom at the starry Governors Awards and, on a recent evening in November, met me for coffee at the Sunset Tower bar in West Hollywood.

All of this appears as easy as breathing for Culkin, who is chatty and clever and charming — gifts that were put to good use during his Emmy-winning run on the HBO series “Succession,” which concluded last spring. But on the day I met up with the 42-year-old actor, he was nevertheless frustrated: His most recent press tour meant that he would have to miss a parent-teacher conference back home in New York.

“My wife was like, ‘We can postpone it and do it over Zoom,’ and I was like, ‘No, no, do it the right way, when they scheduled it. Go,’” he said. “I want to be the one that can go off for a weekend and do work but also be the parent-teacher guy. But I think I’m getting to the place of having to accept that I can’t always get home.”

Family is important to Culkin, who grew up in New York with seven siblings (including his brother Macaulay, of “Home Alone” fame) and now lives there with his wife, Jazz Charton, and their two children. He readily confesses that he tried to pull out of “A Real Pain” when its shooting dates were changed, since the revised schedule meant that his wife and children would be able to visit only at the beginning of the Poland-set production, leaving him without them for nearly a month.

“I was like, ‘I can’t be away from the family for that long,’ and I had a flip-out,” he said.
