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.
The Hound of the Baskervilles (1939 film)
"The Hound of the Baskervilles" marks the first of the fourteen "Sherlock Holmes" films starring Rathbone and Bruce as Holmes and Watson, respectively. It is also notable as the earliest known "Sherlock Holmes" film to be set in the Victorian period of the original stories; all known previous "Holmes" films, up to and including the 1930s British film series starring Arthur Wontner as Holmes, had been updated to a setting contemporaneous with the films' release. It is also the only film in the series to be a strict adaptation of its source material, while subsequent installments would feature original titles and incorporate various elements of different stories.
