Can World War II film long hidden by the Army aid today's veterans?

"The guns are quiet now," is the first line in John Huston's 1946 short film, "Let There Be Light," which focuses on World War II veterans dealing with what we'd today call post-traumatic stress disorder.

Quiet, perhaps. But the echoes of those guns were still ringing in the minds of many returning soldiers -- much as they still are with modern veterans.

Huston, himself a veteran and director of such films as "The Maltese Falcon" and "Treasure of the Sierra Madre," filmed soldiers being treated at Long Island's Mason General Hospital for what at the time was called shell shock.
