The Night Has Eyes is a British film, released in 1942, and not to be confused with Cornell Woolrich's Night Has a Thousand Eyes, which was published three years later and subsequently turned into a good film starring Edward G. Robinson. The British film also had two alternative titles in the US - Terror House and Moonlight Madness. No prizes for guessing which title I prefer.
The Night Has Eyes is based on a thriller by Alan Kennington which was published in 1939. I know very little about Kennington, though apparently in later life he was friendly with the better-known (yet still under-estimated) P. M. Hubbard. The film version of his book is in some respects creaky and melodramatic, as well as fog-shrouded, but it has a number of redeeming features.
One of these is the performance of James Mason as Stephen Dermid, a composer who has suffered severe shell-shock after being wounded while fighting in the Spanish Civil War. Mason manages, not for the only time in his career, to combine the charming with the sinister. A young teacher called Marian (Joyce Howard) falls for him after travelling to the Yorkshire moors with her American chum (Tucker McGuire) to try to discover the fate of her friend Evelyn, who disappeared a year ago.
Stephen is cared for by a housekeeper, Mrs Ranger (Mary Clare, an actress of real ability who played the very different part of Mrs Pym of Scotland Yard) and an odd-job man, Jim. Unfortunately for Marian, it becomes increasingly clear that something terrible happened to Evelyn, and before long she is at risk of suffering a similar fate. Despite the presentation of Yorkshire, a county I love, as a wild blend of fog and bog, and not much else, I found the film rather entertaining.
