The Fighting Generation

The Fighting Generation is a 1944 short film, a public service announcement produced by David O. Selznick and directed by an uncredited Alfred Hitchcock to promote war bond sales during the Sixth War Loan Drive. Jennifer Jones stars as a nurse's aide.
The film was shot in a single day, on October 9, 1944. Rhonda Fleming and actors Steve Dunhill and Tony Devlin were to appear in the scene, according to a call sheet, but in the end, only Jones appears on-screen.
The film survives in the Academy [Film Archive] and was preserved in 2008. The film is part of the Academy War Film Collection, one of the largest collections of World War II-era short films held outside government archives.
