 Vampyr has been released with low quality image and sound as the original German and French sound and film negatives are lost. Prints of the French and German versions of the film exist but most of them are either incomplete or damaged. Vampyr was released in the United States under the titles of The Vampire and Castle of Doom and in the United Kingdom under the title of The Strange Adventures of David Gray. Many of these prints are severely cut, such as the re-dubbed 60-minute English-language Castle of Doom print.
