The official release date of Gun Cargo is 1949, but the cast and the quality of production suggests that it was filmed much, much earlier. A crooked shipowner gets rid of his able-bodied crew when they begin to complain about salary and working conditions. The crew's replacements consist of the scum of the earth. In no time at all (a good thing, too, since the film runs only 49 minutes) the crew begins rumbling about mutiny ("rumble rumble rumble...mutiny mutiny mutiny"). The cast includes former cowboy stars Rex Lease and Smith Ballew and silent film veterans William Farnum and Gibson Gowland. Gun Cargo was lensed in a decidedly economical color process. ~ Hal Erickson, All Movie Guide
