I'll give you a few examples:
Jurassic Park - "When Disneyland opened in 1956, nothing worked."
Big Bang Theory - Penny: "We're riding the Matterhorn in Disneyland?"
Leonard: "Think farther"
Penny: "We're riding the Matterhorn in Disney World?"
Roseanne - Somehow we are given the idea that Dan can just run from Magic Kingdom to Epcot just that easily. Even the monorail ride takes a few minutes in between parks.
Family Guy - The episode where they are in Disney World. There is the Indiana Jones ride which doesn't exist there, only in Disneyland. Sort of the same inconsistency as the Big Bang Theory episode.
So do you just laugh these things off? I do normally. However I wonder if this is done purposely or not. Do they just assume that the majority of people wouldn't have gone to any of the parks? Or both especially? It is a petty mistake in a film/show which falls on the shoulders of the directors for not fact checking but shouldn't show business people know this stuff a little better?
