The photos below depict perhaps two of the most horrifying faces to ever grace the big screen. The first one is the face of Satan that flashed briefly on the screen during the 1973 horror classic, "The Exorcist." The second one is of the horrifying witch that came back from the dead for revenge in the 1963 cult classic "Black Sabbath." I remember watching "Black Sabbath" on WPIX Channel 11's "Chiller Theater" on a Saturday night when I was a kid back in the 1970s. Needless to say, every time I closed my eyes that night to try and fall asleep, I saw that horrible face. With that in mind, I wouldn't stare at these two faces for too long. They might give you nightmares.
By the way, speaking of Chiller Theater, if you would like to refresh your memory on the scary opening titles used for that program, the youtube link is below for your viewing pleasure.
