St. Francis (also known as Nightmare and Dreams, as well as Saint Francis: Dreams and Nightmares) is a French 25 minute anti-war film directed by Berthold Bartosch.
Partially financed by Thorold Dickinson, Bartosch worked on it from 1933 to 1938. Very little is known about it, to the point where there are conflicting reports on whether it was in color or in black & white.
When the Nazis invaded Paris, the film was in the editing stages. Bartosch deposited the film at the Cinémathèque Française, where it was unfortunately destroyed during the Nazi occupation. Reportedly a few still images exist, though they are incredibly rare.
