The film "How Green Was My Valley" is a 1941 American drama directed by John Ford, adapted from the 1939 novel by Richard Llewellyn. It tells the story of the Morgan family, a hardworking Welsh mining family, through the eyes of the youngest son, Huw, set in a South Wales coal mining valley during the late Victorian era. The narrative follows the family's life, the hardships they endure, and the decline of their once-green valley into an industrialized, desolate environment. The film was acclaimed for its emotional depth, storytelling, and aesthetics, winning five Academy Awards including Best Picture and Best Director in 1942, notably beating "Citizen Kane." It is especially noted for its portrayal of social justice themes, labor struggles, family bonds, and environmental changes as the valley transforms from a pastoral paradise into a coal mining region scarred by industry. The movie is remembered as an important cultural work, preserved in the US National Film Registry for its historical and artistic significance.
