Hayley Mills excels in this understated, underrated movie juxtaposing the sordid criminal world (Alan Bates as a murderer on the run) with the innocence of children. Cleverly designed, perfectly acted (by all the children as well as the adults), pithily appropriate screenplay, believable accents (the setting is the Yorkshire moors in England), and a well-balanced, carefully planned production all combine to produce a mesmerising gem of a film. Already a star, Hayley Mills proved she was not just a pretty face and built on her impressive performance in Tiger Bay to create a moving character of budding adolescence, still trapped in childhood innocence and belief. The period of the early sixties is neatly conveyed, and Hayley Mills as Cathy creates a metaphor for the deeper layer of the film's message of the increasing social awareness and diminishing religious belief (despite the traditional Sunday School attitudes and practices) which was gradually bringing about the social change of Britain in the sixties. The story is well told, the drama is dynamic, the actors do a marvellous job and the film certainly deserves to be better known, if not least because it's an early example of Richard Attenborough's production skills.
