Liam Neeson can point to plenty of roles that changed the course of his career, but becoming a father altered something much more fundamental.
The 74-year-old actor told PEOPLE that raising his sons Micheál and Daniel affected his acting, his outlook and even the most ordinary parts of his day. “Everything, even tying my bootlaces” changed after he became a father, Neeson said.
Neeson shares Micheál, 31, and Daniel, 30, with his late wife, Natasha Richardson, who died in 2009. Although both sons are now adults, he said that has not changed how he thinks about them. “They’re always your kids, always,” he said.
The subject came up while Neeson and Zachary Levi were discussing their new thriller The Fix. Levi plays a former CIA operative struggling with an estranged wife and young son while Neeson portrays his former handler and mentor, giving the conversation about parenthood a direct connection to the film.
Fatherhood Changed More Than Neeson’s Acting
Neeson said he believes becoming a father improved his acting, but the change went far beyond his work. Even routine actions somehow felt different once he had children, although three decades later he still struggles to explain exactly why.
He traced that feeling back to a conversation with longtime friend Gabriel Byrne before Neeson was married or had children. Neeson remembered watching Byrne’s young son Jack running around a swimming pool and asking what fatherhood was like.
Byrne told him that when his son was born, he suddenly understood his place in the world. Neeson said that description stayed with him until he eventually experienced the same shift after the births of Micheál and Daniel.
“Something just changed for me, in a great way,” Neeson told PEOPLE, describing the feeling as almost impossible to define. He added that he is still thinking about it roughly 30 years later.
He Was Describing the Same Change More Than a Decade Ago
Neeson’s newest comments closely resemble what he said while promoting Run All Night in 2015. That film also dealt heavily with fatherhood, following a damaged father trying to protect his estranged son.
“As a parent your life is changed forever,” Neeson told IrishCentral at the time. He said parenthood followed him into his acting and remained present in everyday moments such as crossing a road or sitting down in a restaurant.
Neeson also told the same Gabriel Byrne story during that interview, remembering Byrne saying that the birth of his son made his place in the universe suddenly make sense. When Neeson later became a father himself, he said, “Everything just aligned in some way.”
The consistency between the interviews spans more than a decade. Neeson has changed roles, moved deeper into action films and watched both of his sons reach adulthood, but he continues describing fatherhood as something that permanently changed how he experiences ordinary life.
His Sons Followed Different Paths as Adults
Micheál followed his parents into acting and has worked with Neeson more than once. His credits include Cold Pursuit and Made in Italy, and PEOPLE reports that he most recently appeared in the 2026 film Trauma or, Monsters All.
Daniel took a different route after playing sports while growing up. He now operates the De Nada tequila brand and became engaged to his college sweetheart, Natalie Ackerman, in September 2025.
Their adulthood has not eliminated the worry Neeson associates with being their father. In a 2022 AARP interview, he described the familiar parental reaction of realizing a child should already be home and immediately wondering whether something had happened.
That same interview brought him back to the moment Micheál was still an infant. Meryl Streep visited Neeson and Richardson when Micheál was about six months old, looked at the sleeping baby and then gave the new parents her own warning about what they had signed up for.
“You both realize you’re hostages for the rest of your life, right?” Streep told them.
Neeson said she was “absolutely correct.”
