at face value la moustache appear to be an exercise in far fetch and existential conceit . the trailer certainly doesn not allow a prospective viewer any more information than it premise represent a man shave off his moustache in an effort to change his image . his girlfriend doesn not notice . a a matter of fact . no one do . he begin to get increasingly disturb that no one would notice something as elemental a facial hair . and then thing suddenly spiral out of control . certainly it would make anyone think represent come on and now . a thriller about a man lose his mind because no one have notice he shave his moustache off . isn not this take it a little too far . the truth of the matter be and it not la moustache be merely a set up in the most elusive of way and creep up on the viewer like the best of the polanski apartment thriller ( where nothing be a it seem ) and it send the hapless marc ( vincent lindon ) into a world that double in on itself one fold and two fold and while seem chillingly normal . maybe it a commentary on the danger of be too wealthy ( because have we have a struggle couple and something as banal a a moustache wouldn not even enter the picture ) . marc and agnes ( emmanuelle devos ) live what can be call a life in the lap of luxury in a sleek loft apartment . they seem to be elementally happy and until one minor and laughably trivial incident throw them into an increasingly jarring descent into marital alienation of the like of the unhappy couple in george cukor gaslight with the gender switch and which grow creepy a marc suddenly become suspicious of everything around him and wonder if event in his life have even occur . because as simple a that and from the denial of a moustache existence and now his own be in peril . and from here on and the story manage to go into uncharted territory and and give more detail about it would be essentially spoil the fun that this very suppressed and very elegant thriller be . la moustache be an intriguing puzzle in some way akin to the puzzle of cache and where another couple happiness become ensnare in an intrigue that may or may not be happen . sparse and deliberate while not be too slow ( yet not reveal too much too soon ) and this be a high concept thriller that should be see .
