In his day, Director Jean Yarborough worked with all the big names in bad movies (Abbott & Costello, The Bowery Boys, Rondo Hatton and Bela Lugosi.) He even did an unacknowledged adventure series with Mantan Moreland battling Nazis in the tropics (KING OF THE ZOMBIES, LAW OF THE JUNGLE.)Capping off his film career with the ignominious twilight of performers like Carradine, Rathbone and Chaney Jr. seems like a destiny chosen for him by the gods of the B-Movies. Is there something of Greek tragedy in this ending, or is it merely poetic justice? At any rate, it was good to see three actors who had all seen much better days putting in one more turn as despicable villains, and it was a fitting coda for a director whose career was always more remarkable for determination than artistry.
