This presentation features 68 motion pictures produced between 1898 and 1901 of the Spanish-American War and the subsequent Philippine Revolution. The Spanish-American War was the first U.S. war in which the motion picture camera played a role. These films were made by the Edison Manufacturing Company and the American Mutoscope & Biograph Company and consist of actualities filmed in the U.S., Cuba, and the Philippines, showing troops, ships, notable figures, and parades, as well as reenactments of battles and other war-time events. The Special Presentation presents the motion pictures in chronological order together with brief essays that provide a historical context for their filming.
