There are Things that Highlight this Low-Budget Spy Drama based on a True Account.
Ernest Borgnine in a Rather Restrained Performance that doesn't quite Capture the Suspense and Intrigue Needed to Fully Flesh Out the Super-Serious Story.
But it has some Intrigue with Agents on Both Sides Everywhere except Under the Bed.
Gadgets Galore Proliferate Scenes with Tape Recorders, Cameras, and a Myriad of Privacy Penetrating Hardware Showcased Regularly Through this Detailed Drama.
It Depicts the Soviets in Full Force Plotting Their way to World Domination.
The Second Half Kicks-In after a Slow and Talky Start.
There are Interesting Plot Devices as Director De Toth Builds Suspense with Odd Scenes of Behind the Scenes at KGB.
Above Average and Definitely Worth a Watch for Anyone Attracted to Cold-War Espionage Films.
And this was Before the James Bond Films made all of this Big-Box-Office.
