Neeson said it took him about a week to process what had happened.
“It was horrible, horrible, when I think back, that I did that,” he said. “And I’ve never admitted that, and I’m saying it to a journalist. God forbid.”
“Holy s***,” said Tom Bateman, his co-star, who was reportedly sitting next to Neeson during the interview.
“It’s awful,” Neeson continued. “But I did learn a lesson from it, when I eventually thought, ‘What the f*** are you doing’, you know?”
CNN has not been able to independently authenticate the audio. A rep for Neeson has not responded to a request for comment.
Neeson, 66, added that growing up around violence in Northern Ireland taught him that revenge ultimately doesn’t work.
“I come from a society — I grew up in Northern Ireland in the Troubles — and, you know, I knew a couple of guys that died on hunger strike, and I had acquaintances who were very caught up in the Troubles, and I understand that need for revenge, but it just leads to more revenge, to more killing and more killing, and Northern Ireland’s proof of that. All this stuff that’s happening in the world, the violence, is proof of that, you know. But that primal need, I understand.”
