John goes to see a movie – but alas! It’s in 3D, and he didn’t buy any glasses. Everything looks blurred and weird. Can you tell the genre of the film John is squinting at?
3D movies are not as recent an invention as you might think. The first demonstration of a 3D film dates as far back as 1915; during the 1950s, there was an outright 3D craze in American cinema, the likes of which has not been seen again until the release of “Avatar”.
