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.
Adaptations of Sherlock Holmes
Carleton Hobbs portrayed Holmes in a series of BBC radio broadcasts that ran from 1952 to 1969, with Norman Shelley playing Watson. Many of these were broadcast on Children's Hour. Of the many actors who have portrayed Holmes and Watson for the BBC, the Hobbs and Shelley duo is the longest running.
