The Awful Dr. Orloff (1962)
The Awful Dr. Orloff is a 1962 Spanish–French horror film directed by Jesús Franco. It stars Howard Vernon as the mad Dr. Orloff (or sometimes Orlof) who wants to repair his disfigured daughter's face with skin grafts from others, with the aid of a slavish blind henchman named Morpho. The film is considered to be the earliest Spanish horror film. Howard Vernon continued to appear in a number of Franco's horror films up until his death. Franco would later feature a number of blind or disfigured henchmen named Morpho in many of his later horror films, such as Vampyos Lesbos and Revenge in the House of Usher.
