#11: Miriam Flynn as Catherine
Catherine, Eddie’s soft-spoken and endlessly patient wife, adds a gentle counterbalance to Eddie’s wild unpredictability. Her calm acceptance of their unusual lifestyle creates some of the film’s best understated jokes. Catherine’s warmth makes her instantly likable, and her quiet reactions highlight the lovable chaos the Griswolds get swept into.

When the movie was produced, Miriam Flynn was steadily building a solid comedic career. She had worked in both television and voice acting, already proving she had strong timing and versatility. Her role as Catherine helped cement her status as a dependable actress who could shine even in a busy ensemble cast.
