How Long Is “Keep My Grave Open”?

This unsettling but moody low-budget psycho-thriller -- a drive-in version of Repulsion with a Southern Gothic flavor -- stars the eerie-looking Camilla Carr as a demented young recluse who believes herself to be possessed by the spirit of her long-lost brother (who is presumed dead), and slays any man who makes sexual advances toward her -- usually running them through with a sword. Her dementia intensifies, leading her to take her own life by chewing on broken glass (a particularly unsettling scene). The chief plot twist and subsequent dramatic punchline -- involving the brother's true identity and whereabouts -- is a long time coming, but fairly satisfying nonetheless.
