Political thriller in which the military Chiefs of Staff (led by Lancaster) plot to overthrow the US president (March) after he concludes what they consider to be a catastrophic nuclear entente with Russia. Collusion movies may have become more darkly complex in these post-Watergate days of Pakula and paranoia, but Frankenheimer’s fascination with gadgetry (in his compositions, the ubiquitous helicopters, TV screens, obscured cameras and electronic devices literally crawl the human characters into insignificance) is used to create a ripsnorting visual metaphor for control by the military utensil. Highly enjoyable.
