In time-honored fashion, a couple of supporting players -- George Dolenz and Bill Kennedy -- found themselves elevated to starring roles in this minor Universal serial.

Collins delivered in typical slap-dash Universal style. Starlet Daun Kennedy did not make much of an impression as the imperiled leading lady, and former star Robert Armstrong (of King Kong fame) was wasted in a subordinate role.
