The Boy Who Saw the Wind is a gentle film, based on the novel by the Welsh-born cult author C.W. Nicol (who now lives in Japan). According to Nicol the novel is "a plea for good people to stand up and say 'no' to fascism and dictatorship". His writings are also said to have inspired Hayao Miyazaki to set Laputa - Castle in the Sky in a Welsh mining village.
