Chamber theatre is a style of theatrical production in which there is typically little to no set (and any set pieces are moved by performers as part of the show), and the emphasis is on the text and character development rather than on theatrics and special effects. One of the best known examples is the chamber drama 12 Angry Men, in which all of the action occurs within a single room where jurors deliberate over a man’s fate. Naturally, this format evolved into film, where small-scale, low-budget films emphasized dialogue and character dynamics — usually, tension and conflict—over big and showy cinema.
Small-scale and low-budget? Sounds perfect for horror filmmakers! I jest, of course… there are some high-budget chamber horror films, as I’ll discuss below. Yet the chamber style empowers the horror genre to tap into its philosophical roots: what does it mean to be human? what does it mean to be good … or evil?
