As a result of this I read a brilliant selection of James's stories with an introduction by Nigel Kneale and have regularly re-read them - especially late at night during the winter.
Until recently I had not realised that Night of the Demon was based on The Casting of the Runes, and after reading a brilliant blogpost by Anne Billson on films that had scared her I managed to track down a copy on DVD.

It also provided one of the samples for Kate Bush on her Hounds of Love Album, one of my all-time favourite recordings.
Here's a link to the US trailer where it was released as The Curse of the Demon:
