Adaptations of Sherlock Holmes
It has been estimated that Sherlock Holmes is the most prolific screen character in the history of cinema. The first known film featuring Holmes is "Sherlock Holmes Baffled", a one-reel film running less than a minute, made by the American Mutoscope and Biograph Company in 1900. This was followed by a 1905 Vitagraph film "Adventures of Sherlock Holmes; or, Held for Ransom", with H. Kyrle Bellew and J. Barney Sherry in unlisted roles. It was long believed that the film starred Maurice Costello as Sherlock Holmes, but Leslie S. Klinger has written that the identification of Costello in the role is flawed. Klinger states that the first identification of Costello with the role was in Michael Pointer's "Public Life of Sherlock Holmes" published in 1975 but Pointer later realized his error and wrote to Klinger stating
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.
