Just in time for trick-or-treating, another list (via USA Today’s Hip Clicks) brings us the 100 Greatest Horror Movie Performances. I won’t argue with placing Boris Karloff at the top; his work as Frankenstein‘s creature, finding the humanity beneath the monstrous, set the standard for all monster-movie performances that followed. However, the inclusion of a number of terrifying characters (including Anthony Hopkins’ Hannibal Lecter, Anthony Perkins’ Norman Bates, Robert Mitchum’s Harry Powell in Night of the Hunter, and Dennis Hopper’s Frank Booth in Blue Velvet) who are merely sociopathic murderers in films that don’t have supernatural or sci-fi elements inspires the question of whether serial-killer movies count as horror films. Readers, would you place any garden-variety serial killers on your list of top horror performances?
