Expressionist visuals akin to German cinema were allied to the latest sound effects to produce what became known as the `Old Dark House' thriller. The atmosphere is eerie and thrilling which permeates throughout this unsettling chiller. It also reminds me of the Giallo genre, containing many of the elements, yet it was produced decades prior. The first "true" giallo film is usually considered to be Mario Bava's The Girl Who Knew Too Much (1963)
