She never chased trends, but she did build people. That is why her roles remain endlessly rewatchable and why new audiences keep discovering her work through streaming.

Below is a deep look at the performances that define her legacy and explain why her career continues to feel both classic and current.
Moira Rose in 'Schitt’s Creek'
Moira Rose stands as one of the most original television characters of the modern era. On "Schitt’s Creek," O’Hara transformed a former soap opera star into a cultural icon without softening the character’s extremes.
Moira’s shifting accent, hyper formal vocabulary, and rotating collection of wigs were not random eccentricities. They were defensive armor. O’Hara built Moira as a woman terrified of fading into obscurity, clinging to performance as identity.
What made the role unforgettable was the emotional truth beneath the flamboyance. When Moira showed love for her family, it felt earned. The performance redefined what sitcom acting could be and earned O’Hara an Emmy while reshaping the show into a global phenomenon.
Kate McCallister in 'Home Alone'
In "Home Alone," Catherine O’Hara provided the emotional spine of a film famous for slapstick chaos. As Kate McCallister, she played panic and guilt with total sincerity. There was no irony and no exaggeration.
Her performance grounded the movie’s outrageous premise. The frantic airport runs, the desperate bargaining for plane seats, and the relentless determination to get home made the story believable. That authenticity is a major reason the film has endured as a holiday staple.
Delia Deetz in "Beetlejuice"
Delia Deetz could have easily been a flat parody. Instead, in "Beetlejuice," O’Hara turned her into a fully realized character whose seriousness made the absurdity even funnier.
Delia’s self-importance, her artistic pretensions, and her total lack of self-awareness were played with absolute conviction. O’Hara’s physical comedy and razor-sharp delivery matched the film’s surreal tone while keeping Delia oddly grounded. The performance helped turn "Beetlejuice" into a lasting cult classic and established O’Hara as a master of stylized comedy.
Mickey Crabbe in "Best in Show"
As Mickey Crabbe in "Best in Show," O’Hara delivered one of her most controlled performances. Paired with Eugene Levy, she portrayed a woman whose self-worth was tied entirely to winning.
The clipped tone, forced smiles, and barely contained hostility felt unsettlingly familiar. O’Hara’s restraint amplified the comedy.
Cookie Fleck in "A Mighty Wind"
In "A Mighty Wind," Catherine O’Hara blended comedy with genuine musical ability. Cookie Fleck was nostalgic, kind, and emotionally open.
The performance carried real tenderness. O’Hara allowed moments of stillness and reflection, showing how comedy and sincerity can coexist without undercutting each other. It is one of her most human performances.
