1908 - Sidney Olcott's Dr. Jekyll and Mr. Hyde

 While generally, Turner's adaptation is given the titles of the first film adaptation of Strange Case of Dr. Jekyll and Mr. Hyde and first American horror film, some debate does remain on if Olcott's version more accurately holds that title. The film starred Frank Oakes Rose in the roles of Dr. Jekyll and Mr. Hyde. The film was a one-reeler, and was produced by the Kalem Company. Less information exists regarding this film as it was less thoroughly documented, and thus with it having become lost media, information on the film is difficult to scavenge.
