Murderer, you killed them. You killed them all. It’s 1906. Helen is a young mute woman (Dorothy McGuire) working in a New England mansion as a domestic to bedridden Mrs Warren (Ethel Barrymore) who lives with her professor stepson Albert (gorgeous George Brent), a secretary Blanche (Rhonda Fleming) who used to be his girlfriend and is now romancing her newly returned son Steven (Gordon Oliver), verbally abused Nurse Barker (Sara Allgood), drunken housekeeper Mrs Oates (Elsa Lanchester) and her husband (Rhys Williams). A maniac is killing off people with disabilities. After Mrs Warren warns her of the danger to her personal safety she makes plans to leave the dark old house with her boyfriend Dr Parry (Kent Smith), but it is too late. The maniac is in the house, and she is his prey… Mel Dinelli made his screenwriting debut with this adaptation of Ethel Lina White’s 1933 novel Some Must Watch – the idea for the staircase came from a Mary Roberts Rinehart novel. It’s a beautifully mounted gripping Gothic suspenser with an ideal setting, atmosphere and occasional flashes of director Robert Siodmak’s Expressionist roots by DoP Nicholas Musuraca, underscoring the murderousness at its core. Spinechilling from start to finish.
