I love the Fleischer Superman cartoons. The animation is smooth and fluid with vivid colors. The distinct art-deco style, vintage science fiction imagery, and use of noirish shadows gave them a look unlike any other cartoons. The music and voicework is superb. They're fun, accessible, enduring animation classics. While this is a cartoon from Fleischer Studios' successor, Famous Studios, it still tries to maintain the Fleischer style.

Thirteenth in the series starts off with a cool-looking sequence of an arm sinking into a marsh as a car speeds away. A night watchman at a munitions plant has been murdered, so Lois & Clark go undercover to find out what happened. Turns out some of the plant workers are saboteurs. Lois overhears their plot but is discovered. They shove her into a torpedo that will explode when tested. The torpedo is sent to the firing range and Superman must race to save Lois in time.

The best part is when the saboteurs are chasing Lois, as well as the intriguing opening scene. Other than that, this is another straightforward WW2 saboteur story.
