Catherine O’Hara Recalls 'Sickening' Moment She Was Nearly Separated from Her Sons à la Home Alone (Exclusive)

The ‘Schitt’s Creek’ Emmy winner recalled the incident while promoting her new action comedy ‘Argylle’

Catherine O’Hara is not one to judge Kate and Peter McAllister for leaving their son alone Home alone movies.

After famously exclaiming “Kevin!” on screen in 1990 when she realized she had gone to Paris without Macaulay Culkin, her fictional son, O’Hara, 69, and her husband, Bo Welch, had a real scare with their sons Matthew and Luke (now grown.)

“Once we were in New York; I think it was New York. Bo and I entered the subway, we turned around, the door was closing, but it wasn’t on,” she recalls. “I screamed and people screamed with me. Everyone joined in.”

Fortunately, the door opened again and the boys made it. “It makes me sick to think what could have happened,” says O’Hara, who stars in the new action comedy Argyll.

“What is happening? You are on the train, it is going to the next station. And you think, will it stay in that place? Will they be safe? Will we be back? Are they going to think, ‘Oh, I’m going to get on the next train and go there?'” says O’Hara. “We didn’t have phones.”
