I got a wonderful book for Christmas this year- Beating the Devil, which is all about the making of one of the best horror/monster movies ever made.
it's written by Tony Earnshaw, and until they have a seance and call up the artists who have passed away, there will be no finer source about this book. ever.
it has everything you would want to know about the movie. some people would like to have this sort of thing on the DVD, but I'm one of those luddites who would rather read a book than read material off a tv or computer screen. much more leisurely and much less eyestrain.
it's really well written and contains tons of interviews and archival history from the movie and from England as well. it also makes me want to read the source material for the movie, the short story "Casting the Runes" (which made Dana Andrews eat prunes, I've heard tell).
