It was reported in contemporary news accounts that a sequel had been filmed in the Lake Tahoe area simultaneously with the principal photography for the first Doc Savage, but the sequel was never completed because of the poor box office for this first film.
Characters use "extinguisher globes" to put out a fire in Doc's home. In real life, glass globes filled with carbon tetrachloride or other fire suppressants were marketed in the 19th century. They have a long shelf life, and are now collectibles, but are only minimally effective against fires.
Except for the campy tone of the film, Doc Savage: The Man of Bronze was fairly faithful to the novels and characters, which included such elements as: Doc's trilling (although it sounded like bells tinkling rather than a more lifelike trilling (such as a cat purring); the bickering between Monk and Ham; Renny's signature expletive, "Holy Cow!"; Renny's love of slamming his fists through solidly constructed doors or door-panels; Monk's pet pig, Habeas Corpus; Doc's "Fortress of Solitude", the penthouse headquarters on the 86th floor of the Empire State Building; the Crime College and Doc's brain surgery techniques to remove the criminal element from crooks he had captured, making them incapable of committing further crimes; Doc's dramatic descent down a skyscraper elevator shaft; Doc's daily two-hour exercise regime; Doc standing on an automobile's running board in hot pursuit; Johnny's use of long, obscure words when simple words would suffice; Johnny's signature expletive "I'll be superamalgamated!"; a plethora of retro gadgetry such as heat detector, globes of fire-fighting chemicals (extinguisher globes), phonograph-based recording machine, remote-controlled aircraft, a ray gun disguised as a cigarette lighter, lightweight bullet-proof vests, miniaturized SCUBA-type underwater breathing gear, and the Whizzer, a prototype helicopter--all his inventions and designs.
This was to be the first in a series of films based on a popular series of pulp novels. The poor box office returns cancelled plans for any further film productions.
