I resaw Vampyr (1932) which was directed by Carl Dreyer. The version I saw was the restored 72 minute version rather than the 62 minute version previously available on tape. It's a strange almost dreamlike film full of shadows. The film was financed by Baron Nicolas de Gunzburg. He agreed to provide the finance provided he appeared in the film. He played the lead role of Allan Gray under the name Julian West. Not a professional actor and a somewhat wooden performance.
I thought the earlier scenes were more effective than the later scenes. The original film seems to have been slightly longer suggesting that the restored version is incomplete.
There are two sisters in the film Leone and Giselle. The IMDB synopsis has Giselle as the vampire's victim but the book with my DVD has Leone as the victim.
