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 Private Life of Sherlock Holmes
The Private Life of Sherlock Holmes is a 1970 DeLuxe Color film in Panavision written and produced by Billy Wilder and I. A. L. Diamond, and directed by Wilder. The film offers an affectionate, slightly parodic look at Sherlock Holmes, and draws a distinction between the "real" Holmes and the character portrayed by Watson in his stories for "The Strand" magazine. It stars Robert Stephens as Holmes and Colin Blakely as Doctor Watson.
