Literary adaptation
Works of literature have been adapted for film from the dawn of the industry. Some of the earliest examples come from the work of Georges Méliès, who pioneered many film techniques. In 1899, he released two adaptations — "Cinderella" based on the Brothers Grimm story of the same name and "King John", the first known film to be based on the works of Shakespeare. The 1900 film "Sherlock Holmes Baffled", directed by Arthur Marvin featured Arthur Conan Doyle's detective character Sherlock Holmes intruding upon a pseudo-supernatural burglary. The film, considered the first detective movie, ran for only 30 seconds and was originally intended to be shown in hand-cranked Mutoscope machines.
Sherlock Holmes (Stoll film series)
From 1921 to 1923, Stoll Pictures produced a series of silent black-and-white films based on Sir Arthur Conan Doyle's Sherlock Holmes stories. Forty-five short films and two feature-length films were produced featuring Eille Norwood in the role of Holmes and Hubert Willis cast as Dr. Watson with the exception of the final film, "The Sign of Four", where Willis was replaced with Arthur Cullin. Consequently, Norwood holds the record for most appearances as Sherlock Holmes in film.
