"In his posthumous memoir, screenwriter Charles Bennett claimed that the script was actually based on a series of strange experiences he had following World War 1. According to Bennett, he grew increasingly superstitious when the war ended and his imagination started working overtime. He began believing he could cause terrible things to happen just by being in the same room with someone after bearing witnesses to multiple tragedies that he felt personally responsible for... The personal nature of the script bolsters the film's interesting pedigree making it a unique curio that fans of classic horror and suspense should appreciate." - Kimberly Lindbergs, TCM's Movie Morlocks
