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.
Young Sherlock Holmes
Young Sherlock Holmes (also known with the title card name of "Pyramid of Fear") is a 1985 American mystery adventure film directed by Barry Levinson and written by Chris Columbus, based on the characters created by Sir Arthur Conan Doyle. The film depicts a young Sherlock Holmes and John Watson meeting and solving a mystery together at a boarding school.
