One of our faves from Christopher Guest’s mockumentaries, including “Waiting for Guffman,” “Best in Show” and “A Mighty Wind,” O’Hara got her start at Second City in Toronto in 1974 before becoming a series regular on “SCTV.”

A tremendous character actress, she’s also brought her touch to memorable roles in “Beetlejuice,” “Home Alone” and  ”The Nightmare Before Christmas.”

She was inducted into Canada’s Walk of Fame last year.
