Like her Canadian compatriots, O'Hara got her start in Toronto's Second City, where she learned how to perfect improvisation. This talent for spontaneous humor and dialogue has informed many of her roles over the years. This list testifies to O'Hara's abilities as an actor, showing she's worked with some of the most creative comedic forces in the industry.

Sheila Albertson In Waiting for Guffman (1996) - 7.5

O'Hara has acted in almost every Christopher Guest ensemble mockumentary, which includes other actors like Eugene Levy, Fred Willard, and Parkey Posey. In each of these films, Guest focuses his lens on the quirky lives of people invested in creative pursuits ranging from small-town theatre to national dog shows to folk music.

In Waiting for Guffman, Guest's first feature, O'Hara plays Sheila Albertson who, along with her husband Ron, is an amateur actor who makes a living as a travel agent. Ron and Sheila like to wear matching outfits, and they get cast as the leads in Corky St. Clair's play, which will be a sweeping historical review of Blaine, Missouri, the focus of the film.

Delia In Beetlejuice (1988) - 7.5

Tim Burton's cult classic wouldn't be the same without O'Hara's iconic portrayal of Lydia Deetz's stepmother Delia, a temperamental sculptor.

Delia guts the Maitlands's beloved home, turning it into a post-modern labyrinth that mimics the harshness of her art.

Things get really interesting when they realize Lydia, played by Winona Rider, can see them.

Kate In Home Alone (1990) - 7.6

O'Hara does an amazing job acting out any parent's worst nightmare: realizing you left one of your children behind on your way spend Christmas in Paris.

Moira Rose In Schitt's Creek (2015 - 2020) - 8.3

O'Hara is brilliant as the former soap opera star turned slumming long-term hotel guest Moira Rose on Schitt's Creek. After the fortune she shares with her husband leaves the country with their thieving accountant, the Roses have no choice but to relate to the town father Johnny, played by Eugene Levy, bought for his son David as a joke.

Moira has more wigs and breakdowns than any character in television history, and adjusting to life in Schitt's Creek takes its toll on her. Fortunately, she was able to save enough of her high-end couture to maintain her very unique, and very iconic, look.
