Histoire du soldat inconnu (1932) is made up of footage from 1928, when an anti-war treaty had been signed. The filmmaker uses intellectual montage to make the point that militarism and the institutions that support it are clearly going to make mincemeat of the treaty’s ideals. The approach is pretty simple, juxtaposing marching soldiers with religious processions. At that point in film history, it was probably still a pretty novel idea that one could cut from a pompous politician speaking to a small dog yapping.
