Psycho, with its magnificently pitiable madman Norman Bates,
came out a year later, and there's no question about that
film's greatness and influence. But this icky Brit horror
film, written by Leo Marks and directed by Michael Powell,
deserves inclusion as an early study in psychosexual sadism.
Young Mark's little quirk is that he can feel erotic
fulfillment only when he films his female victims as he
murders them. The movie camera, Powell says, is a fatal
weapon, in a crime committed for the pleasure of... you,
dear complicitous viewer.
