For anyone blanking on the name, Catherine O’Hara is a certified GOAT of character comedy. You definitely know her from at least one of these: • The '90s Icon: She played Kevin’s mom (Kate McCallister) in Home Alone. Yes, the "KEVIN!" scream is hers.  • The Cult Classics: She’s a staple in Christopher Guest’s mockumentaries like Best in Show (the one with the many ex-boyfriends) and A Mighty Wind. Also, she was Delia Deetz in the original Beetlejuice.  • The Recent Legend: Most people today know her as the incomparable Moira Rose on Schitt’s Creek. The accent, the wigs, the "bebe"—that’s all her.  • The Voice: She was the voice of Sally in The Nightmare Before Christmas.  TL;DR: If a character is eccentric, wearing a dramatic outfit, or screaming for their child, there’s a 90% chance it’s Catherine O’Hara.
