he Stars Look Down is based on A. J. Cronin's 1935 novel of the same name, about injustices in a mining community in North East England. While the novel follows the development of three young men in the small mining town, the film focuses on just one of them; the smart David Fenwick who gets a scholarship to university, meets a girl who only marries him because her former boyfriend has abandoned her, and eventually returns to the mine town as a teacher and takes part in a futile rescue effort when the mine is flooded, trapping both his father and his younger brother.
