While Catherine O'Hara is best known for her iconic roles on beloved films and TV shows like Home Alone, Best in Show, Schitt's Creek and Beetlejuice, the late actress was also a former Saturday Night Live cast member - for a week, that is. "I got asked to be on Saturday Night Live. And of course I said yes," O'Hara told People back in 2024 of her short-lived time on the sixth season of the hit sketch comedy show. "Who doesn't want to do that?" At the time, O'Hara was also a cast member on the hit Canadian comedy sketch show SCTV.
