Daniel Radcliffe's son "didn't miss" him when he was working long hours on Broadway.
The 36-year-old actor was performing eight shows a week across six days during his recent stint in one-man show Every Brilliant Thing, and while he enjoyed having more free time in the day to spend with his and partner Erin Darke's three-year-old boy - whose name hasn't been publicly disclosed - he admitted it took a toll eventually, though his child didn't feel the same.
He told E! News: "There's some ways in which theatre is great for having a kid. You get so much time during the day to be with them, but the six days a week—that gets tough eventually and like I really missed him.
"He was fine, he didn't miss me."
The Harry Potter star joked it will be a "victory" if his son grows up to enjoy any of his work.
He said: "If he likes any of them, that will feel like a victory as a parent.
"I feel like nothing your parents do is cool, so he'll probably just watch me and be like, 'What are you doing?'"
But Daniel isn't looking forward to the day when his boy is curious to see Kill Your Darlings, the 2013 movie on which he and Erin met and fell in love, particularly because of the intimate scene they share.
He said: "God forbid he ever watches the film where me and his mom met on, because it's just.. it's just going to be an awkward watch for a variety of reasons for him.
"Honestly, if I could stop him from ever knowing I was an actor or famous, I would do that.
"I'm in this beautiful phase right now where I'm just his dad to him and nothing else, and I'm gonna hang on to that for as long as possible."
Every Brilliant Thing features audience participation amid a reflection on the good things in life, and Daniel admitted his son was always on his mind during the performance.
He said: "I found doing a show that says something about the world that I really wanted to be a part of saying - my son's a real inspiration in wanting to say that.
"And when I was thinking about certain things in the show, I would think about him a lot, so he was actually quite energising."
