Calling himself the "purple monster," the humanoid invader sets about gaining control of Layton's rocket project. Opposing him is Craig Foster, former Secret Service man, who episode by episode tries to thwart the monster's attempts to acquire rocket components. Will Craig ever suspect that his closest associate is really the monster? Written by Rod Crawford <puffinus@u.washington.edu>

User Reviews

Great fun for an eight year old.
25 August 2003 | by acmeronSee all my reviews

I saw this serial in 1945 at the Fox Egyptian Theater in San Diego. The scene of the Purple Monster taking off in his rocket ship in the last chapter was forever engraved into my mind. It was great fun a few years ago to see the serial again. I was amazed at how many people who were killed appeared again and again, plus that ford convertible that was crashed a few times had 9 lives.

I have seen a color poster of the Purple Monster, and the alien is dressed in a red costume with gold trim. In the black and white movie of course he is black and silver; perhaps they should have called him the Art Deco Monster.
