Shocked that her Scottish fiancée Gerald MacTeam ('50s sci-fi regular Richard Carlson) would unexpectedly call off their engagement shortly after becoming Baronet of Castle Craven, Kitty Murray (Veronica Hurst) and her aunt Edith (Katherine Emery) travel to the dismal chateau, only to find an abrupt and inhospitable Gerald living alone with a pair of cryptic servants and apparently harbouring a dark secret. This is a strange little film, with an effectively creepy build (with all the requisite 'haunted castle' tropes) and a completely off-the-wall (and admittedly unexpected) denouement. You will either laugh incredulously or feel a sense of melancholy as the dark secret o' the Clan MacTeam falls into place. William Cameron Menzies does a nice job setting the mood in this budget sci-fi/horror and the often high-contrast black and white cinematography is quite effective. Carlson, who has been threatened by everything from stranded aliens to Amazonian gill-men, is not very creditable as a Scottish heir but Hurst is fine, albeit in a pretty standard role. Fun and novel in an odd way. If you haven't seen it, try to avoid spoilers (not that there is some brilliant 'twist ending', but the sheer oddness of the climax is best experienced naïvely). Note: made in 3D but I watched a 'flat' version.
