It’s a boom time for Kathryn Hahn who stars in Hulu’s “Tiny Beautiful Things” Friday.

After decades of steady, often surprising work, she scored an Emmy nomination as centuries-old witch Agatha Harkness in the Disney+ “WandaVision” (2021).  She’s a regular on “Central Park” the AppleTV+ animated musical series. Now in “Tiny Beautiful,” adapted from the same-named book by best-selling author Cheryl Strayed (“Wild”), Hahn is a very troubled Clare.

Her husband and daughter have ejected her from the house. Yet things change when she becomes an advice columnist. “I did not see her life as a ‘wreck’ but when we meet her, she’s not at a great point in her life,” Hahn, 49, allowed during a Zoom interview.

“Honestly, at this age if you just scratch beneath the surface, most people you find are not totally satisfied with exactly what is going on in their lives at that particular moment.

“To me, this particular age is a time of reckoning. A time of like, Whoa, where am I? Is this what I want? Is this where I’m supposed to be? Am I happy?”

Clare is offered a new path: “To take on an anonymous non-paying advice column from an old friend of hers. This awakened something in her that had long been dormant. It starts a torrent of feelings that she’s able to pour into this advice column. She begins to find her voice again. And so I found her very, very relatable.”

“Tiny” boasts two mighty producers: Reese Witherspoon and Laura Dern. What kind of difference do they make?

“I respect them both. You immediately know you’re in good creative hands. But I didn’t see them during the making of this. I saw Reese for like two seconds, which was lovely.”

It’s been three years since Hahn played Agatha Harkness. Did she have any clue it would lead to the spin-off “Agatha: House of Harkness”?

“I love it but No!” she exclaimed, “I certainly had no idea. I took the job just as the job and had zero idea that this could possibly be more.”
