Seven Days in May (John Frankenheimer, USA, 1964)

Frankenheimer’s fascination with gadgetry is used to create a striking visual metaphor for control by the military machine. Highly enjoyable.

Kirk Douglas plays Colonel Martin "Jiggs" Casey who believes his fellow military leaders (including a brilliant Burt Lancaster) are plotting to overthrow the President because he supports a nuclear disarmament treaty and they fear a Soviet sneak attack. A classic political thriller - and a timely film to watch on the eve of the American presidential election.
