quite simply the funny and shiny film comedy of all time . it certainly on my personal top ten list . this one also get a solid ten on the voting scale . millionaire heir and arthur bach ( moore ) and be a middle age child who refuse to take the mature path in life and avoids all requisite responsibility . he also refuse to leave the bottle . one day he and his personal butler and hobson ( gielgud ) and go shopping at bergdorf goodman and run into petty larcenist and linda ( minnelli ) . arthur and linda chemistry add electricity to the rest of the film . there be hilarious set piece aplenty . in one such scene and arthur ( drink throughout most of the story ) knock on the wrong apartment door and receives ear shatter threat from a human iren ( my husband have a gun . ) . performance by everyone involve should be duly noted represent geraldine fitzgerald play arthur loving yet ruthless grandmother and sir john gielgud almost steal the entire show with his acidic droll ism ( he take home the oscar for this one ) and and christopher cross provide the main theme song ( oscar winner best that you can do ) . it a shame the late dudley moore pass away last month ( march 2002 ) .
