Oh Swp... you have fantastic taste in literature. Oh and I heard they're making Call of Cthulu into a movie... but then I saw the trailer and don't want to see it.
Glad to know there's another horror buff in here.
(ever read Neil Gaiman? not necessarily horror, but definitely fantastical)
A silent film of Call of Cthulu was made in 2005 I believe. I have it on my Netflix. Apparantly its very good.
