 Let There Be Light (1946 film)

Let There Be Light (1946) — known to the U.S. Army as PMF 5019 — is a documentary film directed by American filmmaker John Huston (1906–1987).It was the last in a series of four films directed by Huston while serving in the U.S. Army Signal Corps during World War II.Intended to educate the public about posttraumatic stress disorder and its treatment among returning veterans, the film's unscripted presentation of mental disability led to "Let There Be Light" being suppressed by the U.S. government; it was not released until the 1980s.
