In Blitze, Dietmar Brehm generates a sordid Kuleshov effect, where the face of the voyeur is transformed by what he watches and what he watches is transformed by being watched. The impact of the gaze is marked by lightning bolts as the voyeur opens his eyes to a series of images, illicitly watching people in their beds. See the Schwartzer Garten (Black Garden) series in Programme Two for more Dietmar Brehm.
