The Sign of Four is a 1932 British crime film directed by Graham Cutts and starring Arthur Wontner, Ian Hunter and Graham Soutten. The film is based on Arthur Conan Doyle's second Sherlock Holmes story The Sign of the Four and was made at Ealing Studios.
The film is also known as The Sign of Four: Sherlock Holmes' Greatest Case.
A young woman needs Sherlock Holmes for protection when she's tormented by an escaped killer. However, when the woman is abducted, Holmes and Watson must infiltrate the city's criminal underworld to track down the young woman.
Jonathan Small, a prisoner serving a lengthy sentence on the Andaman Islands cuts a deal with two army officers, Major Sholto and Captain Morstan, in command of the prison. He reveals the location of a stash of loot in exchange for their help in helping him to escape from jail. The proceeds are to be split equally between the three of them.
Sholto and Morstan go to investigate the treasure which is hidden in an old Indian fortress. When they unearth the valuable trinkets behind a brick wall it sparks a violent quarrel between the two men with each wanting to take all of the treasure. After a struggle Sholto kills his accomplice and returns to England without fulfilling his pledge to help Small escape.
The Sign of Four (2001) is a Canadian television film directed by Rodney Gibbons and starring Matt Frewer and Kenneth Welsh. The movie is based on Arthur Conan Doyle's second Sherlock Holmes story.
The second of four Holmes adaptations starring Frewer as Holmes, was preceded by The Hound of the Baskervilles in 2000, and then followed by The Royal Scandal (a blend of "A Scandal in Bohemia" and "The Bruce-Partington Plans") also in 2001, and The Case of the Whitechapel Vampire (an original story) in 2002.
Frewer's portrayal of Holmes was largely criticized.
Unlike the source novel, the movie features Holmes meeting with a Scotland Yard chemist named Professor Morgan who not only identifies the poison which killed Bartholomew Sholto but creates an antidote for Holmes.
Tonga is portrayed not as the savage pygmy of the novel but instead as an Asian with facial markings.
