This is definitely one to watch without reading Doyle first. This jingoistic outpouring must have seemed fair at the time but is now a little transparent. Rathbone has played a much more subtle Holmes who is intelligent without being a Hollywood style super-hero. Any more and he would be flying. Bruce is also a bit hammy, he plays so dumb you wonder how he made it through medical school. Good but I preferred Rathbone's earlier portrayals.
The premise of Sherlock Holmes plopped into WWII sounded as if this wartime thriller would be worth a watch, but it was just a string of bland B-movie tropes. This is the most incompetent Watson you’ve ever seen.
The first of Universal Pictures' 12 contemporary updates of the immortal sleuth, also begins an informal trilogy, with Sherlock Holmes now taking on the Nazis. They retain Basil Rathbone as Sherlock Holmes and Nigel Bruce as Dr. Watson from the two period adventures released by Fox in 1939. But there's almost nothing left of Arthur Conan Doyle's credited story, His Last Bow.
In fact there's just the famous patriotic speech at the end. There isn't much narrative and little deduction. This is intended to be pro-British propaganda. There's a fairly horrifying portrayal of the blitz, but reassurance that with the great detective, the nation will prevail. He investigates the link between a Nazi broadcaster and industrial sabotage. And a planned invasion.
Presumably the voice of terror refers to Lord Haw Haw's pro-Axis radio transmissions. The mystery is, who in the British security council is a traitor? There's a relishable support cast, including Henry Daniell as the prime suspect and Evelyn Ankers as the leader of the cor-blimey Cockney criminals doing their bit for the country.
Great to see Thomas Gomez on his screen debut, as a cold-hearted killer. The main positives are the rich, noirish photography and the wonderful orchestral score written for the series. Minor director John Rawlins creates little suspense, but it still entertains because whatever else is uncertain, the characters of Holmes and Watson will never let you down.
