"La Guerre est Finie" aka The War is Over (1966) from French master Alain Resnais, is a taut intellectual yet very much visual thriller. Yves Montand is in his mature prime, and Ingrid Thulin so quietly sensual, while Geneviève Bujold gave an impressive debut performance. Resnais' creative cinematic approach in rich visual play mixed with voice-over narration, aptly intensified the suspense. We're literally inside Montand's character Diego's head - thinking with him, seeing through his eyes, having memory tracking along with him in either flash back or flash forward. We feel Thulin's subtle moves as Marianne - a slight turn of her head, gentle extension of her neck, every movement so delicately modest yet sensual in volumes. Bujold's Nadine has such delicious youthful verve befitting the character - she is the exciting accent. Thulin and Bujold each has an intimate segment opposite Montand delivered in Resnais' unique and refreshing points of view. It is cinematic nuance truly savory and appreciation optimal.
Cinematography in black and white by Sacha Vierny is poignantly appropriate - suspense would probably be lessen if delivered in color. Music score by Giovanni Fusco further ensured the distinctive quality of this film. You can tell this is no Hollywood thriller formula. In fact, the film can very well be a character study of Diego or a visual journey through the interplay of character relationships, yet it's suspenseful nonetheless. The beginning segment with veteran actor Michel Piccoli as the shrewd custom inspector questioning Montand's Diego certainly is tense as any other spy thriller yarn.
The war in the title can very well be within Diego: to decide whether to continue this life of 'professional revolutionary' or to start anew a 'normal' life with Marianne. The dilemma also carries over to Marianne: to decide to stay in Paris or love conquers all in pursuit after Diego (to the point of being a matter of life and death, indeed). "The War is Over" may seem complex, but it's actually an easier to follow film than other Resnais endeavors. Give it a try. It's available on DVD. Caution: do ignore the dubbed in English alternative - it would not be the real thing, definitely non-flavorful. Experience the film in French with English subtitles.
