An outstanding RKO "Hitchcockian" like thriller it stars Dorothy McGuire, George Brent and Ethel Barrymore (along with a scene stealing Elsa Lanchester), an eerie theremin score by Roy Webb and direction by Robert Siodmak in full German Expressionism overdrive. McGuire plays a deaf mute domestic servant in a creepy Victorian mansion (that's almost a character unto itself) while a serial killer lurks about the vicinity killing women suffering from physical afflictions.
A triumph of set design, mood and atmosphere, its come to be regraded as a precursor to the Italian giallo thrillers of the 1970's (Dario Argento has mentioned it as one of his influences). Hopefully MGM will get off their collective butts and remedy this situation soon. At the very least licence it someone like Criterion, who's released in the past couple of years a growing collection of classic Hollywood films such as THE UNINVITED, I MARRIED A WITCH & SULLIVAN'S TRAVELS.
