Signal Corps Photographic Center was a crossroads for many films and filmmakers from World War II to 1970.  Even when the assignments and productions were in other studios, other units, other theaters and other services, much of the footage and many of the films resided at SCPC.  It became part of the library and distribution system of the Army Motion Picture Depository.
