Sherlock Holmes squares off once again, in this 1943 film, against his diabolical nemesis Professor Moriarty (Lionel Atwill), who kidnaps the inventor of a new technologically advanced bomb site and threatens to sell the invention to the Nazis. England's fate hangs in the balance as Holmes and Watson must break a secret code of dancing men to stop the Nazis and rescue the inventor. Dennis Hoey makes his debut as Inspector Lestrade of Scotland Yard.
Between 1939 and 1945, Universal Pictures filmed 14 Sherlock Holmes mysteries starring Philip St. John Basil Rathbone as Sir Arthur Conan Doyle's legendary detective and William Nigel Bruce as his faithful sidekick Dr. Watson. All but two of the films were "updated" to World War II England and often included Axis spies or saboteurs as antagonists. Each movie has been lovingly restored by the UCLA Theatre Archives from 35 mm master copies into a digital format and may be viewed in either colorized versions or in the original black and white.
