Though the horror film was not officially born until Universal Pictures released Frankenstein in 1931, there were many silent films that contained terrifying scenes and horrific elements. Many of the early horror soundies drew much of their inspiration for visual design and thematic development from the silents. This filmography includes all silent films that were horrific in nature, containing one or more of the stock horror movie elements, e.g., haunted houses, ghosts, witches, monsters, the occult or hypnotism. Each entry includes release date, running time, cast and credit information, contemporary review quotes when available, and in the case of foreign films, the original title and country of origin.
