Slack forties serial.
9 October 2017 | by MozjoukineSee all my reviews

In those long gone nineteen forties children's matinees it was clear that this one was a down sizing of the adventure serials that the kids prized. The fantastic elements which made them memorable had been replaced by guys in suits slugging it out and the occasional model shot crash.

The cast played it all straight faced. The studio, that had produced FLASH GORDON, rolled it out without any hint of guilt for abandoning us to the inanities of Sam Katzman at the rival supplier. I still recall the worm turns turn by Byron Foulger however.
