Question: don't be afraid of the dark creatures origin
Answer: Del Toro has attributed the idea of giving the creatures in the film a fairy origin to the work of the writer Arthur Machen , saying in an interview : `` I love the Welsh author Arthur Machen and his idea that fairy lore comes from a dark place , that it 's derived from little , pre-human creatures who are really , really nasty vermin but are magical in a way , living as they do for hundreds of years .
