I wish I had time to go through this thread, but I know TX Chainsaw Massacre has been mentioned. I'll try to contribute something else:
BEGOTTEN. That is a silent film with pretty much constant insect simulation and disembowelment.
I also have to say that Art Zoyd's alternate score for "Nosferatu" is pretty amazing.
I'll also second Gil Melle's "Andromeda Strain", the guy who did the theme to Night Gallery. Early versions of the record came in a fold out hexagonal sleeve that I may be able to afford some time.
As for Morricone, I have to say my favorite is "The Thing" as Carpenter's influence on his work is extremely rewarding to me, but also, this compilation of "Experimental Morricone" has some great stuff on it, especially "La Citta".
