director kerrigan have clearly do his homework . it sure look to me and a person who believe that the dardenne brother ( luc and jean pierre ) and the french speaking belgian film maker and be the most interesting filmmaker in the world today and that kerrigan think so and too . he have get down proper the semi documentary technique that the belgian brother perfect in la promesse and rosetta and le fils and and lenfant . the camera follow the main character solely . we see that person and usually in close up . the camera will occasionally swing away to show that person point of view or to show who he be talk to and but the camera be mostly on the character face or look over the shoulder at where he or she be go . there be no musical soundtrack ( even in the opening title and close credit ) but there be a carefully prepared mix of city sound and background noise . luckily and kerrigan have not just ape a technique and but have also tap into the same kind of sympathetic and humanistic observation of behavior and optimism about the human race that the dardennes bring to their story . william keane be a part time street person who suffer from schizophrenia . he haunt grand central station try to get passer by to look at a picture of a little girl in a newspaper clipping . have you see this girl . people hurry away . he wash up in rest room . he sometimes sleep outdoors and not notice the rain . he imagine that kidnap scenario be go on in the station . he frantically mutter to himself about the grow danger around him . he attack a bystander and throw a couple of punch before walk quickly away . sometimes he have quiet period when he will use a disability check to buy himself some shelter in a seedy extend stay hotel . like a certain academy award win crowd pleaser from a few year ago and keane tackle the question and can a schizophrenic eventually be able to discern his own vision from reality even if he still see the vision . however and keane be about real person and as brought to life by the fine ( but largely unrecognized ) british actor and damian lewis . anyone who have daily experience with street people can see the truth of lewis performance . my lovely wife have work a a nurse aide in a psych ward of a big city hospital also confirm the truthfulness of lewis work . what a marvelous difference from ron howard tear jerk mush and russell crowe hammy and over the top performance of twitch and jerk . keane slowly develop a story out of this man circumstance that bring him to one crucial moment of decision and a powerful resolution in the final second of the film . i absolutely love keane and highly recommend it .
