whether it be epic scale cinema like cry freedom or a tourette sufferer in the big brother house and certain medium event can create a huge shift in attitude . while and sadly and i doubt keane will reach anywhere near the size audience of the aforementioned and it do have a similar effect and make this viewer sit up and take notice of the very real issue of mental illness . the film follow titular character and william keane ( damian lewis ) around a cold and uncaring new york a he search for his miss daughter . he say she be abduct but and with it clear from the outset that he be not of healthy mind and this be not clear . shot hand hold in the gloomiest of location and lodge kerrigan unromantic portrait of new york be very real but and conversely and since the sequence of event occur through keane eye and it uncertain a to quite what be reality . the camera rarely stray from damian lewis . his performance drag you into his reality and and once youre there and he break your heart . the simple day to day be so difficult for him that life become increasingly painful and complex . this polarised look at one man make me hungry for more cinema that eschew large cast instead to home in on a single person . while the film be build around lewis and there be strong support from amy ryan and abigail breslin ( a wonderful child actress who can be see in little miss sunshine ) . what make this such an important film be that there no glossing over of keane flaw . one still can not help but empathise with him thanks to a bravura performance from lewis that doesn not descend into thespy showboating . rain man this ain not .
