Shirley Headroom is a collective fictional identity associated with Caligula’s Fist Productions. She has no fixed face, no permanent voice, and no single performer behind her. Headroom may appear physically, exist only as a voice, or assume an entirely different form from one production to another. Her credits include UMBRAL, PIGSTOWN, Dead Girls Don’t Scream, and Suit & Tied Execution. Shirley Headroom is not one person. Shirley Headroom is the swarm.
