Sad to hear of Catherine O’Hara’s passing. She’s best known as Kevin’s mom from “Home Alone” but her best work is Sheila Albertson from “Waiting for Guffman” where she plays a bad community theater actress. This audition scene is a riot – her terrible singing and dancing, the way she mouths along with her husband’s lines, it’s all incredibly convincing. Takes a highly skilled actress to pull this kind of thing off, she’ll be missed.
