The Canadian National Film Board's release on China in the war is the story of the rise of a new nation from the land of the oldest civilization in the world. It is the story, also, of the aggressor whose ruthless execution of long cherished plans made the transformation possible. The subject is a picturesque and inspiring one, and the commentary, as written by Stuart Legg and spoken by Lome Greene, is calculated to point up the dramatic qualities of the pictures. The spirit of China and its new leaders is presented graphically, while the cause of her fight - ten years longer than ours- becomes identified with our own. The material is not new, but the presentation is the pointed, intelligent work, characteristic of the "World in Action."
