Daniel Radcliffe isn't just grateful for the applause on Broadway—he's absorbed in the things his 3-year-old son says and does every day.

The Harry Potter actor, currently nominated for a Tony Award for his performance in Every Brilliant Thing, opened up to E! Online about how fatherhood has reshaped what he finds meaningful. "My list of brilliant things is entirely comprised of things my son says or does right now," he told the outlet in May.

The playwrights even joked about it. Radcliffe revealed that he and the creative team "agreed that if there was a sequel to this play, it would be because the character had children and just thousands of more brilliant things happen when you're with them."

His son's accent is the real draw. The toddler, born to Radcliffe and partner Erin Darke in 2023, is caught between two worlds—English dad, American everything else—and the result is pure comedy.

"My son's weird accent, I'd say, is a brilliant thing," Radcliffe explained, "because he's obviously pulled between me—English—and the rest of who he knows, which is American. And so he's just got this great, weird little voice. You can never predict how he's going to say a word."

Case in point: someone gifted the kid a toy Lamborghini. He's now permanently renamed it "zucchini." Radcliffe refuses to correct him. "I will never correct because it's brilliant," he said on a March episode of The Late Show With Stephen Colbert.

His son has no idea who Harry Potter is. When a DVD showed up on their kitchen table, Radcliffe casually asked the toddler who was on the cover. "He didn't recognize me, which was great," Radcliffe told The New York Times. For now, he's savoring being "just his dad" before the Potter fame catches up.

"It's frankly terrifying to have a human being in the world that I care this much about," Radcliffe admitted to E! News in October 2023. "But it's awesome, and he's the best thing that's ever happened."
