Слово встречается в следующем контексте:

‘The funny thing about it is: like all science fiction films, it’s not actually about ‘then’, it’sabout ‘now’. And what you do is – by way of a cautionary tale – you say to people: Now look, if we allow things to continue the way they’re going now, it will get this bad. So it is about ‘today’, and it digs in, it really does address those issues on a big scale – it’s not just a chase movie. I mean it is mainly a chase movie! Because the whole thing moves forward like a shark! It’s like it has to keep going forward in order to live.’
So Nigel Floyd says Children of Men is a cautionary tale – it’s a warning.
