Catherine O'Hara missed “Home Alone” costar John Candy's wedding because she was sleeping

"Why am I admitting this?" the actress wondered on Julia Louis-Dreyfus' podcast.

Catherine O'Hara really enjoys getting a good night's sleep — and maybe even a few extra hours on top of that.

On a recent episode of fellow actress Julia Louis-Dreyfus' Wiser Than Me podcast, O'Hara revealed that she she slept right through the wedding of her friend and Home Alone costar John Candy.

The subject came up when Louis-Dreyfus asked if there was anything O'Hara wished she had spent less time on in her life. The answer was sleeping.

"Maybe I missed some things," the Beetlejuice Beetlejuice star mused. "I missed John Candy's wedding. I was asleep."

Laughing, O'Hara asked aloud, "Why am I admitting this?"

Candy and O'Hara were longtime friends, having worked together since the '70s, when both were members of the Second City comedy troupe in Toronto. They later costarred on SCTV, which aired from 1976 to 1979, and in the 1990 holiday classic Home Alone.

In Home Alone, O'Hara famously played Kate McCallister, the suburban mom desperate to get back to her mischievous 8-year-old son, Kevin (Macaulay Culkin), after he's accidentally left behind when the family takes a trip to Paris.

Candy had a small but memorable role as Gus Polinski, who fancies himself the "Polka King of the Midwest." He and his band, the Kenosha Kickers — known for such "fairly big hits" as "Polka Polka Polka" and "Polka Twist" — give Mrs. McCallister a ride on the last leg of her trip to reunite with Kevin.

Candy's wedding took place in 1979, when he married Rosemary Margaret Hobor. She was with him until he died in March 1994 after suffering a heart attack at 43.

O'Hara spoke fondly of the late star of such movies as Spaceballs, Uncle Buck, and The Great Outdoors earlier this year, when she told PEOPLE she had "such a crush" on him. But she was well aware that he was taken.

"I wouldn't claim he was interested in me that way," O'Hara said. "But he was always really lovely to me in Second City Theater."

She added that she never shies away from telling others about her experiences with him.

"It's so nice to be able to not have to make up any bull, because people loved him," she said. "And when people ask, 'What was he like?' they want to hear what they think he'd be like. And it's so lovely to be able to validate their guesses about what he would be like in person."

Candy would have turned 74 this year. Listen to O'Hara on Wiser Than Me above.
