Actress Catherine O’Hara, who played his mother in both 1990s films, honored him at the event, reported.

In an emotional speech, O’Hara recalled how Culkin became a global star when he was just 10 years old.

“Home Alone was, is, and always will be a beloved global sensation,” she said. “The reason families around the world can’t go a year without watching and loving Home Alone together is Macaulay Culkin.”

Home Alone was a huge box office success when it was released in 1990, grossing $476.7 million (approximately €437 million). Culkin and O’Hara returned for the sequel to Home Alone 2, set in New York in 1992. Both have since become cult films and, for many, Christmas staples.

“Yes, he had a great script and a great director,” O’Hara added, giving credit, “but it’s Macaulay’s pitch-perfect performance as Kevin McCallister that gives us this little boy on an extraordinary adventure every time.”

Addressing Culkin, she said, “I know you worked hard, but you made acting seem like the most natural thing in the world. It was like we set up a trap for a real little boy named Kevin to make a movie and he just agreed to do it for fun.”

They then hugged, Culkin wiping away tears and O’Hara thanking him for bringing “your fake mom who left you home alone not once, but twice” to the ceremony.

Natasha Lyonne, who co-starred with Culkin in the 2003 movie “Evening Monster,” also performed at the ceremony. “Mac, I’m so proud of you,” she said.

“I remember our first date in a bar on the Lower East Side. It was on some stairs at the back, in some place, nameless, unimportant. We were about to start shooting a true crime film about Michael Elig’s crimes in the New York underground rave scene of the 90s. You played Michael Elig, I played Brooke, someone from your inner circle. We met, and I remember thinking, “He’s my friend.” And I really was.”

Other attendees included Culkin’s partner Brenda Song and their two children, his brothers Rory and Quinn, his “Party Monster” co-star Seth Green and his sister-in-law Paris Jackson.
