If you're in the mood for theory cinema, you'll find just about every argument posited by the best of the eighties feminist thinkers exacted upon 20 years prior in Michael Powell's Peeping Tom. Max is a cinematographer and porn photographer who kills women with a rather ingeniously original method of employment. It is a film which delves directly into just what it is to play voyeur. It is one I highly recommend - especially the Criterion version, whose supplemental features are quite enthralling.
