I think I mentioned it already, but as a refresher, it's about an agent for the Department of Agriculture who travels to a tiny town to find out why no-one's responding to telegrams. It initially started as a clear 'Bad Day At Black Rock' style paranoid thriller but rapidly turned into a short, sharp environmental horror. Yeah, I think I can call it that. Oh, and it's set in the heart of the Dust Bowl in the late 1930's! Wait that's right I did talk about it before because I linked to this awesome documentary that I used as my primary research source: http://www.pbs.org/wgbh/americanexperience/films/dustbowl/
Seriously, if you have an hour spare check it out - you can see how something like this is ripe for horror writing!
Watched In The Mouth of Madness again tonight. Man, I fucking love that film. Pardon the swearing but I fucking love it. I'd marry it if such a thing was possible. Marry it and fuck its brains out!
Screw it, I'm going to do a post soon that's just a massive love letter to it.
