Catherine Anne O'Hara (born March 4, 1954) is a Canadian-American Emmy and Gemini Award-winning actress and comedienne. She is well known for her comedy work on SCTV and for her film roles as Delia Deetz in Beetlejuice, Kate McCallister in Home Alone, Sally in The Nightmare Before Christmas and the series of mockumentary films written and directed by Christopher Guest. Career O'Hara was born and raised in Toronto, Ontario to a large Irish Catholic family. She started her acting career in 1974 as a cast member of The Second City in Toronto.

She was an understudy for Gilda Radner until she left for Saturday Night Live. Two years later, this theatre troupe created the television series SCTV, on which she became a regular performer. Memorable O'Hara characterizations on the show included Las Vegas scorcher (I wanna bear your children!) Lola Heatherton, buzzer-happy game show contestant Margaret Meehan, raunchy nightclub comedian Dusty Towne, soap opera seductress Sue Ellen and stage actress Sue Bopper Simpson. In the late 1970s, she did various voice-overs for a number of cartoons, which would continue throughout her career.

During a short time in the early 80's when SCTV was in between network deals, she was hired to replace Ann Risley when Saturday Night Live was being retooled in 1981. However, she quit the show without ever having made an appearance on it, choosing to go back to SCTV when the show signed on with NBC and was back on the air. Her SNL position was then given to fellow Canadian Robin Duke, who had also replaced O'Hara for a season on SCTV. She had roles in many films over the years, including Martin Scorsese's After Hours in 1985, as well as parts in two Tim Burton films, Beetlejuice and The Nightmare Before Christmas. ...show less
