At the beginning of the Pop sitcom’s holiday special, family matriarch and former soap star Moira Rose (Catherine O’Hara) rolls over in bed on Christmas Eve morning and tells her husband Johnny (Eugene Levy), “Wake me when it’s over.” Ever since the Roses lost their fortune and gilded lifestyle — and fled to the crassly-titled town of the show’s title — Moira has been no fan of the holiday. Not so much for O’Hara.

“I’m sad when it’s over. The saddest thing you can probably do is put that tree out in the garbage,” O’Hara says with a laugh. “Well, I’m lucky I have a home!” In the special, Johnny dreams of his family’s past lavish holiday parties and sets out to soothe their sorrows by throwing a last-minute shindig. The cast also includes Daniel Levy (Eugene’s son) and Annie Murphy as David and Alexis, Johnny and Moira’s entitled children.

Comedy veteran O’Hara, 64, is best known for starring alongside Levy in “SCTV” sketches and a string of classic Christopher Guest films including “Best in Show,” “Waiting for Guffman” and “A Mighty Wind.” She recently spoke with The Post by phone from her LA home.

What does the episode reveal about the family?
It shows you a taste of their old life, and you see what maybe Johnny and especially Moira are missing. And I love that when Johnny does relive it in his dreams, he wonders why they miss it so much.

There are flashbacks to extravagant Rose family parties. Were those scenes shot in a real mansion?
It’s a ridiculously big house in Toronto. We did the opening scenes there for Season 1 and then just a day again there in June. I love seeing any house decorated for Christmas, but that house looked pretty wild. Overdone.
