Peeping Tom
Loner Mark Lewis works at a film studio during the day and, at night, takes racy photographs of women. Also he's making a documentary on fear, which involves recording the reactions of victims as he murders them. He befriends Helen, the daughter of the family living in the apartment below his, and he tells her vaguely about the movie he is making.
The core experience hinges on fear, voyeuristic terror, and the killer’s disturbing acts; it is widely regarded as a psychological horror film where horror mechanisms drive the narrative and viewer reaction, not merely a crime thriller. Removing horror would fundamentally alter the work.
Best for viewers looking for a scary, atmosphere-heavy and psychological horror movie.
