Film As the first Sherlock Holmes story published,
A Study in Scarlet was among the first to be adapted to the screen. In 1914, Conan Doyle authorised a British
silent film be produced by
G. B. Samuelson. In the film, titled
A Study in Scarlet, Holmes was played by James Bragington, an accountant who worked as an actor for the only time of his life. He was hired for his resemblance to Holmes, as presented in the sketches originally published with the story. As early silent films were made with film that itself was made with poor materials, and film archiving was then rare, it is now a
lost film. The film was successful enough for Samuelson to produce the 1916 film
The Valley of Fear. A two-reel short film, also titled
A Study in Scarlet, was released in the United States in 1914, a day after the British film with the same title was released. The American film starred
Francis Ford as Holmes and was not authorised by Doyle. It is also a lost film. Aside from Holmes, Watson, Mrs. Hudson, and Inspector Lestrade, the only connections to the Holmes canon are a few lifts of character names (Jabez Wilson, etc.).
Audio Edith Meiser adapted
A Study in Scarlet into a four-part serial for the radio series
The Adventures of Sherlock Holmes. The episodes aired in November and December 1931, with
Richard Gordon as Holmes and Leigh Lovell as Watson. Parts of the story were combined with "
The Adventure of Charles Augustus Milverton" for the script of "Dr Watson Meets Mr Sherlock Holmes", one of multiple radio adaptations featuring
John Gielgud as Holmes and
Ralph Richardson as Watson. The episode first aired on the
BBC Light Programme on 5 October 1954 and also aired on
NBC Radio on 2 January 1955. The story was adapted for the
1952–1969 BBC radio series in 1962 by
Michael Hardwick, with
Carleton Hobbs as Holmes and
Norman Shelley as Watson. It aired on the
BBC Home Service. Another British radio version of the story adapted by Hardwick aired on 25 December 1974, with
Robert Powell as Holmes and
Dinsdale Landen as Watson. The cast also included
Frederick Treves as Gregson,
John Hollis as Lestrade, and
Don Fellows as Jefferson Hope. A radio dramatisation of the story aired on
CBS Radio Mystery Theater during its
1977 season, with
Kevin McCarthy as Holmes and Court Benson as Watson.
A Study in Scarlet was adapted as the first two episodes of the BBC's complete Sherlock Holmes
1989–1998 radio series. The two-part adaptation aired on
Radio 4 in 1989, dramatised by
Bert Coules and starring
Clive Merrison as Holmes,
Michael Williams as Watson, Donald Gee as Inspector Lestrade, and
John Moffatt as Inspector Gregson. It was adapted as a 2007 episode of the American radio series
The Classic Adventures of Sherlock Holmes, with
John Patrick Lowrie as Holmes, Lawrence Albert as Watson,
Rick May as Lestrade, and John Murray as Gregson. In 2023, the podcast
Sherlock&Co adapted the beginning of the story in its first episode, "Mr Sherlock Holmes", but only alluded to the mystery itself at the very end and in the following episode. It starred Paul Waggot as Watson and Harry Attwell as Sherlock.
Television The
1954–1955 television series (with
Ronald Howard as Holmes and
H. Marion Crawford as Watson) used only the first section of the book as the basis for the episode "The Case of the Cunningham Heritage". The book was adapted into an episode broadcast on 23 September 1968 in the second season of the BBC television series
Sherlock Holmes, with
Peter Cushing in the lead role and
Nigel Stock as Dr Watson. It was adapted as the second episode of the 1979
Soviet television film,
Sherlock Holmes and Dr. Watson (the first episode combines the story of their meeting with "The Adventure of the Speckled Band"; the second episode adapts the actual Jefferson Hope case). A 1983 animated television film adaptation was produced by Burbank Films Australia, with
Peter O'Toole voicing Holmes. In both the 1968 television adaptation featuring Peter Cushing and the 1983 animated version featuring Peter O'Toole, the story is changed so that Holmes and Watson already know each other and have been living at 221B Baker Street for some time.
A Study in Scarlet is one of several stories not adapted for
the television series starring
Jeremy Brett between 1984 and 1994.
Steven Moffat loosely adapted
A Study in Scarlet into "
A Study in Pink" as the first episode of the 2010 BBC television series
Sherlock featuring
Benedict Cumberbatch as a 21st-century Sherlock Holmes, and
Martin Freeman as Dr Watson. The adaptation retains many individual elements from the story, such as the scribbled "RACHE" and the two pills, and the killer's potentially fatal
aneurysm (although it is located in his brain rather than his aorta), as well as their profession at the time of the killings. However, the entire backstory set in America is omitted, and the motivation of the killer is completely different. It also features
Moriarty's presence. The first meeting of Holmes and Watson is adapted again in the Victorian setting in the special "The Abominable Bride". "The Deductionist", an episode of
Elementary, contains many elements of Hope's case, including the motivation of revenge. The story was more closely adapted in the season 4 episode, "A Study in Charlotte". "The First Adventure", the first episode of the 2014
NHK puppetry series
Sherlock Holmes, is loosely based on
A Study in Scarlet and "
The Adventure of the Six Napoleons". In it, Holmes, Watson and Lestrade are pupils at a fictional boarding school called
Beeton School. They find out that a pupil called Jefferson Hope has taken revenge on Enoch Drebber and Joseph Stangerson for stealing his watch. "Scarlet Story", the series' opening theme tune, is named after the novel. The name of "Beeton School" is partially inspired by ''
Beeton's Christmas Annual''. "A Study in S", the eighth and ninth episodes of Japanese Anime "Moriarty the Patriot" was loosely based on the novel, sharing names and motives with much of it, but changing the crime's characters' nationality to fit the setting and remove all references to Mormonism.
Other media A Study in Scarlet was illustrated by Seymour Moskowitz for
Classics Illustrated comics in 1953. It was also adapted to graphic novel form by
Innovation Publishing in 1969 by James Stenstrum and illustrated by Noly Panaligan, by
Sterling Publishing in 2010 by
Ian Edginton and illustrated by
I. N. J. Culbard, and by Hakon Holm Publishing in 2013 illustrated by Nis Jessen. In 2014,

Southwark Playhouse in London in March 2014. In February 2019, a new adaptation of
A Study in Scarlet was staged at DM Performance Works at the Factory in
Nuremberg, Pennsylvania. It was adapted by Bill Amos under the title
Sherlock Holmes and the Scarlet Avenger. In August 2025, the play was produced a second time by The Pennsylvania Theater of Performing Arts in
Hazleton, Pennsylvania. In June 2022,
Pitlochry Festival Theatre produced a new adaptation by playwright and actor Lesley Hart,
Sherlock Holmes: A Study in Lipstick, Ketchup and Blood performed in an outdoor amphitheater by two performers. The production uses
A Study in Scarlet as a play within a play set in a post-apocalyptic future. ==Allusions in other works==
