This is quite a Gothic tale of horror, including sundry gory bits. The castle is expectedly dark and brooding, and Corman creates an eerie atmosphere very well.
I spotted two directional errors. The handguns are revolver like, and I do not think such guns were used in Europe in the early years of the nineteenth century. Also, the servant Stefan often stands too close to the Baron, and to Lieutenant Duvalier. For reasons that become clear later, he could assume such familiarity with the Baron. However no nineteenth century officer of the French army, especially one of aristocratic lineage, would tolerate such behaviour from a minion.
Jack Nicholson said of the film, 'This is the only Hollywood film with a complete script that has absolutely no story.' This about sums it up. It should be watched for the camera-work and the ambiance.
