Here's an interesting documentary for all you Cthulhu cultists and lovers of "unutterable horrors" out there, a biography of HP Lovecraft with analysis of his work. The music's a bit over the top, but it has a fairly well-chosen panel of talking heads, including Neil Gaiman, Peter Straub, Guillermo Del Toro and John Carpenter. Enjoy!
Oh and just a thought, but does anybody else wish someone would make a creepy animated film based on the Cthulhu mythos? I could just imagine an animated version of Shadow over Innsmouth... that would be awesome...
