At The Witching Hour, Peg surveys some lists of best Halloween films.
For pagan-themed horror films, or those including witches, at any rate, you can’t beat The Wicker Man, The Craft, Practical Magic (Griffin Dunne, 1998), The Exorcist (William Friedkin, 1973), Rosemary’s Baby (Roman Polanski, 1968), The Devil Rides Out (Terence Fisher, 1968), and The Dunwich Horror (Daniel Haller, 1970).
I would not exactly call Rosemary’s Baby Pagan-with-a-capital-P, but it is still wonderfully chilling as it moves from innocence to realization.
And what about The Call of Cthulhu?
I was very impressed with the Call of Cthulhu, and look forward to The Whisperer in Darkness. (Their “Shoggoth on the Roof” is also brilliant, if you like parody…)
