Excellent Cold War political drama with star power...
“Seven Days in May” is a political thriller about an attempted military coup of the United States. Set during the nuclear age and the anxiety and fear it produced, the movie focuses on three key characters, Joint Chiefs of Staff Chairman Gen. James Mattoon Scott (Burt Lancaster), U.S. President Jordan Lyman (Fredric March), and Col. Martin “Jiggs” Casey (Kirk Douglas), the man who discovers a dangerous plot may be brewing.<br /><br />Lyman has just signed a treaty with the Soviet Union to disarm all nuclear weapons. The public is unhappy, calling the move foolish. Scott believes the President’s decision has left the country at a strategic disadvantage and has, along with several other military leaders, planned a secret plot to seize power.  Most of the movie deals with Col. Casey learning bit by bit of the complicated plot, deciding how to act, and convincing others that the plot is real.<br /><br />Director John Frankenheimer (“The Manchurian Candidate”) and writer Rod Serling have fashioned a gripping, dramatic “what if” scenario, very much a product of its time. It still packs a powerful punch, and Lancaster and Douglas are excellent. Lancaster’s Scott conveys both authority and arrogance, while Douglas’ Casey, who’s Scott’s right-hand man, runs through a range of emotions — admiration, loyalty, doubt, concern, and determination. He’s the man in the middle — the guy responsible for preserving democracy.<br /><br />A sub-plot involving blackmail features Ava Gardner, but rather than furthering the plot, it serves as an unwelcome distraction, slowing the film’s otherwise brisk pace.<br /><br />The only bonus feature on the Blu-ray release is commentary by director John Frankenheimer.

Here is a brief synopsis of the title : It happens with startling swiftness and violence. An armed cadre seizes state control. Fortunately, a coup d’état can’t happen here. Or can it? A classic of suspense directed by John Frankenheimer (The Manchurian Candidate, Ronin) and written for the screen by Rod Serling (The Twilight Zone), Seven Days in May tautly explores that possibility. At odds are a popular general and Joint Chiefs of Staff Chairman (Burt Lancaster) and an unpopular president (Fredric March) with a pacifist agenda. At stake is the survival of the Republic. A vigilant colonel (Kirk Douglas) uncovers the scheme. But are the seven fateful days ahead enough time to derail a takeover? The clock is ticking..
