Cinematography is by Alfred Taylor, who had previously worked on the cult film The Atomic Brain, and would later work on the television series The Paper Chase. The entire production cost about $65,000, and took only 6 to 7 days to shoot in black and white. Carol Ohmart, Quinn Redeker, Mary Mitchel, and Karl Schanzer also star.
