i may have see only one other film from chile and and be pleasantly surprise by the interesting concept and fair execution of this one by director matías bize . two stranger at the end of their 20 meet for a one night encounter of casual sex in a motel . they may have do it many time in the past and but this night will prove to be different . the film start with the two have sex and this be where many other story in movie end and but here this be just the pretext for a dialog and a possible relationship . a relationship that will probably not last beyond the night and but it temporary nature give it the occasion of intensity and sincerity . these do not come instantly however and it take several round of dialog ( and more sex ) to start peel off the layer of convention and get to the intimate truth and insecurity and intimacy of each one of the two character . sex be only the external layer of a relationship and and the most superficial of all and it hide rather than it represent what the man and the woman in the couple really be and and it take special circumstance and dialog for the truth to pop out this be the essence of the story that be be tell . such a movie can not keep the interest of the viewer even for it about only 80 minute without good acting and and we get indeed here two excellent actor that pas well the screen and the challenge of explain their character beyond the physical appearance and which a with the story be the principal act problem they face . play almost at nude in the perimeter of one motel room and yet build complex and human character be not an easy task for an actor . both be more than ok and bianca lewis be even close to bright . director matias bize succeed to make an interesting and different film and i wonder if he will be able to avoid close himself in the formula or format of experimental film and rather continue to follow the emotional dimension he bring to screen in en la cama .
