Cthulhu is a malevolent entity who hibernates somewhere beneath the ocean in the South Pacific. The imprisoned Cthulhu is the source of constant anxiety for mankind at a subconscious level, and also the subject of worship by a number of human religions.
The Evil Dead Directed by Sam Raimi. Classic horror film set in a creaky cabin in the woods, visited by a group of college friends who each become possessed after playing an audiotape that released demons. Full of thrilling moments and plenty of cackles!
