Lionel Atwill, who plays Professor Moriarty in the film, earlier played James Mortimer in The Hound of the Baskervilles (1939).See more »
Continuity: In the shots of Dr. Tobel peering through his bombsight, the bomb-release switch is clearly shown as being a black Bakelite line-cord rocker switch, mounted inline on the bombsight's electrical trip-wire. Yet in the last bomb-drop shot, Dr. Tobel uses a large round push-button switch to release the bomb, and it appears to be mounted on the end of a trip-wire, not inline on the wire.See more »

Middling effort., 8 March 2004
Author: Robert J. Maxwell ( from Deming, New Mexico, USA

The first two Rathbone/Bruce movies were pretty good. Not just because they were in period but because their production values were good and because some effort went into the script. Only the first, "The Hound of the Baskervilles", was based on a Conan-Doyle novella. The second was a pastiche made famous on the stage by Gillette.

Then the franchise was moved to Universal Studios and a series of mostly declining quality was established. This was an early example. It's not terrible, not embarrassingly bad, it just loses something in being updated to the 1940s and in not having the atmosphere Conan-Doyle managed to inject into his characters and into the atmosphere itself. Not to mention some of Conan-Doyle's sometimes unwittingly delicious bon mots -- "The wind sobbed like a child in the chimney."

"The Secret Weapon" doesn't tell us much we don't already know about Holmes and Watson. There is a variation on Conan-Doyle's "Dancing Men" but not really much else that's too interesting. I never cared much for Lionel Atwill as an actor, and he looks especially clunky as Moriarty. Moriarty should be a reptilian ectomorph with an oscillating head.

Still, this is okay for fans of the series. Homes wears his hair combed from back to front on the sides, which is a little different. I wish the code had allowed him to do some cocaine once in a while. The best of the Universal films was unquestionably "The Scarlet Claw," so if you have to choose, choose that one to watch.
