Hemp for Victory is a black-and-white United States government film made during World War II and released in 1942, explaining the uses of hemp, encouraging farmers to grow as much as possible. During World War II, the Marihuana Tax Act of 1937 was lifted briefly to allow for hemp fiber production to create ropes for the U.S. Navy but after the war hemp reverted to its de facto illegal status.
The film was made to encourage farmers to grow hemp for the war effort because other industrial fibers, often imported from overseas, were in short supply. The film shows a history of hemp and hemp products, how hemp is grown, and how hemp is processed into rope, cloth, cordage and other products.
Before 1989, the film was relatively unknown. The United States government denied ever having made such a film. The United States Department of Agriculture library and the Library of Congress told all interested parties that no such movie was made by the USDA or any branch of the U.S. government.
In 2008 efforts were made to make a sequel of the movie by UK-based production houses as a series of short films. It was developed as a three film series of 60 minutes each.
