Erm, well, in all honesty, this British Pathé film from 1931 makes it far more mysterious than I ever thought possible.
I think this is a film about sex, but it gets there via a circuitous route involving mould (‘mould is most particular about whom it marries…’), sticklebacks and an alarming amount of spiders (arachnophobes be warned).
Any footage actually involving human beings is strangely rapey. But on the whole, it’s worth it for the quote: ‘It’s fatal to allow anything female to become bored.’
Those pesky ovaries again, eh?
