You joke, but it's scary that it wouldn't be out of the realm of possibility these days.
While I doubt we'll be forced to sit through a lecture on how one of the original mermaids in the Sub lagoon was secretly a white-passing transgender Latina, I do think there's an opportunity to get a few of the women's names out there who got Disneyland off the ground. There's Ruth Shellhorn, the lady landscape designer who did almost all the park landscaping in 1955, for one. Also the more famous lady Imagineers; Alice Davis, Mary Blair, Harriet Burns. Any others? I'm tapped out, at least for the 1950's.
But then there's the simple fact that the majority of Imagineers in 1953-1956 were white men. I know it's unfashionable to mention that demographic, but they can't tell the story of Disneyland without showing a lot of middle aged white guys wandering around a dusty Anaheim orange grove for a year.
On the flip side, he could get some pretty good comedy in there by including Jack Lindquist and his old Cadillac convertible he bombed around Anaheim in during the mid 50's.
That said, I don't have high hopes for this movie at all. I just read Mr. Green's bio on Wikipedia and it's not hopeful. He's not a Californian, he's born and raised and educated back East and he lives in South Carolina. He directs cheesy comedies and gory horror movies that aren't big hits. Now I'm kicking myself for telling him to take the
Marceline To Magic Kingdom tour at WDW, because he probably actually will and think he's done his research. Oops!
