I grew up in Kentucky, a border state, meaning it was a slave state that did not secede with the Confederacy. In school we had textbooks produced for nationwide use that addressed slavery as the main reason for the secession. But teachers made it clear that if we wanted to pass the test, the reason for the war was "state's rights." Still, we knew better. It was an early lesson in political disconnect from reality.
You know, we talk about how audiences were scared by mediocre effects (by today's standards) and attribute it to suspension of disbelief and the fact that we didn't have anything better. But then there's TV. On a black-and-white cathode ray tube, the creature was as clear as any other actor (meaning not all that much) and was perfectly believable.
I've read about the World War II Evacuee Girl costume in years past. The reasons it survives is because schools in Britain use it for re-enactments of the children's evacuation when they study World War II. Costume manufacturers/advertisers made a huge mistake in labeling it as Anne Frank.
When I was a Girl Scout, we never had slumber parties. But the non-Scout slumber parties we had always involved boys.
