You’ve seen her face. You’ve definitely heard her voice. Honestly, Miriam Flynn is one of those "hey, it's that lady!" actors who has quietly built a career so massive it makes your favorite A-lister’s resume look like a sticky note. Most people know her as the sweet, slightly frazzled Cousin Catherine from the National Lampoon’s Vacation series. But that’s just the tip of the iceberg.
She’s been in everything. Really.
From the stages of Second City in Chicago to the recording booths of your favorite childhood cartoons, Flynn is a master of the "neighbor next door" energy that Hollywood can’t get enough of. She doesn't just play characters; she inhabits them with a specific kind of Midwestern warmth that feels like a hug from an aunt you actually like.
The Griswold Connection: Why Cousin Catherine Stuck
If we’re talking about Miriam Flynn movies and tv shows, we have to start with the chicken. Or, more accurately, the way Catherine prepares it. Flynn first appeared as Catherine Johnson in the 1983 classic National Lampoon's Vacation. She was the perfect foil to the high-strung Griswolds—living in a Kansas farmhouse with Randy Quaid’s Cousin Eddie, serving up questionable meals with a smile that suggested everything was totally fine, even when it clearly wasn't.

Most actors might have been overshadowed by Randy Quaid’s... well, everything. Not Miriam. She played Catherine with a grounded sincerity that made the duo work. She returned for the sequels, including the legendary Christmas Vacation (1989) and Vegas Vacation (1997). She even popped up in the 2003 TV movie Cousin Eddie's Island Adventure. While the sequels varied in quality, Flynn’s performance remained the glue. She made us believe that someone as kind as Catherine would actually stay married to a guy who empties a chemical toilet into the sewer.
That Voice You Hear Everywhere
Here is a fun fact to drop at your next trivia night: Miriam Flynn is basically the voice of your childhood. After the tragic passing of Linda Gary in 1995, Flynn stepped in to voice Grandma Longneck in The Land Before Time franchise. She didn't just do it once; she voiced the character across nearly a dozen direct-to-video sequels and the TV series.
Her voice acting credits are a "who's who" of animation:

- Poil in The Spooktacular New Adventures of Casper.
- Jean Tasmanian Devil (Taz's mom) in Taz-Mania.
It’s a rare talent to be able to jump from a prehistoric Apatosaurus to a cartoon devil’s mother without missing a beat. Flynn has a vocal range that manages to be both soothing and comedically sharp, which is probably why she’s been a staple in the voice booth for over four decades.
The Queen of the "One-Off" Guest Spot
Beyond the big franchises, Flynn is a legend of the sitcom guest star circuit. If a show was popular in the 80s, 90s, or 2000s, there is a 90% chance she was in it. She’s popped up in Cheers as Phyllis Henshaw, the Petersons' neighbor. She’s been in Family Ties, Murphy Brown, and The Simpsons (voicing Miss Barr in the classic episode "Moaning Lisa").
She had a recurring role as Sister Helen on Grounded for Life, where she played the strictly-but-hilarious nun with perfect timing. More recently, she’s been seen in modern hits like Shrinking, 9-1-1, and The Lincoln Lawyer. She even appeared in the 2023 film Self Reliance.

Why Miriam Flynn Matters
In an industry that often tosses character actors aside as they age, Flynn has remained remarkably consistent. She’s a product of that legendary Second City improv era, training alongside greats like Shelley Long, George Wendt, and Catherine O’Hara. That improv background is evident in her work—she has a way of reacting to the chaos around her that feels spontaneous and real.
She represents a specific type of Hollywood success. She isn't a tabloid fixture. She isn't chasing Oscars. She’s a working actor who has mastered the art of being indispensable. Whether she's playing a mother, a grandmother, a neighbor, or a literal sheep, she brings a level of professionalism and heart that makes every project she touches just a little bit better.
If you want to dive deeper into her filmography, don't just stick to the Griswolds. Look for her early work in the short-lived sitcom Maggie (1981), which was her first big starring vehicle. It’s a great example of her leading-lady potential that the industry eventually traded for her "all-star" character actor status.
