Pop Culture Isolation / Film

• Fear of a Black Hat, contrasted with This is Spın̈al Tap (which can also fit)
• Discussed in Smokey and the Bandit, when Carrie mentions that Bandit doesn't know much about the theater or any of the things she's interested in and Bandit comes back by saying that she doesn't know anything about people like Richard Petty or Waylon Jennings. "When you tell somebody somethin', it depends on what part of the United States you're standin' in as to just how dumb you are."
• Priyanka Chopra is one of the top actresses in Bollywood and Miss World 2000. In the US, she's probably best known as the singer of the NFL Thursday Night Football theme song, "In My City" or as the star of Quantico.
• Many of the adult actors in the Harry Potter films are known to younger non-UK/Irish audiences only for their roles in the series. Examples include Richard Harris, Michael Gambon, Robbie Coltrane, Richard Griffiths, Fiona Shaw, Timothy Spall, Imelda Staunton, Jason Isaacs, Zoë Wanamaker, David Thewlis, Brendan Gleeson, Jim Broadbent, Ian Hart, Julie Walters, Mark Williams, Miranda Richardson, Adrian Rawlins, Geraldine Somerville, and Robert Hardy, who work as prolific stars back home often pale in popularity compared to Potter. The ones who avert this include Alan Rickman (somewhat), Emma Thompson, Kenneth Branagh, Warwick Davis, Gary Oldman, Ralph Fiennes, Helena Bonham Carter, and Bill Nighy. And then you have "two-hit wonders" like Maggie Smith (Downton Abbey) and David Bradley (Game of Thrones), or actors now known for a different role entirely, like David Tennant (Doctor Who) and Michelle Fairley (Game of Thrones).
• Nosferatu is much less known nowadays for being a German Expressionist horror classic than it is for the ending gag in the SpongeBob SquarePants episode "Graveyard Shift".
• In-universe example: In the movie A Mighty Wind, the folk singer groups throughout the making of the documentary are fawning all over their common producer, Irving Steinbloom. During the ending, after the audience has spent almost two hours caring about the participants, you see how the rest of the world treats Folk Music singers: mild interest and relegation to playing background music at medical supply conventions.
• Lana Clarkson is much less known nowadays as being among the stars of cult classic sword-and-sorcery films such as Deathstalker and Barbarian Queen than she is for being the woman Phil Spector was convicted of murdering inside his home in 2003.
• In-universe example: In Turning Red, the boyband 4*Town is popular enough among teens for over 30,000 of them to pack Toronto's SkyDome for one of their concerts with a ticket price of $200 yet Mei's mother, Ming, only seems to become aware of their existence after a TV ad for said concert. Amusingly, in contrast, Ming is familiar with Céline Dion who as described on the Real Life page, was also subject to this among English-speaking Canadians.
