I just saw the Austrian slasher film Angst (1983), also released under the title Fear. It's atypical in the horror genre for its use of narration over dialogue, and the cinematography makes it feel like one long scene. The movie is comical at points where he reveals his incompetency, and the actor does a good job at seeming out of touch. It's also based on a real killer, but I won't say who cause I don't want to spoil it.>>3289
