City of Gold is a 1957 Canadian documentary film by Colin Low and Wolf Koenig, chronicling Dawson City during the Klondike Gold Rush. It made innovative use of archival photos and camera movements to animate still images, while also combining narration and music to bring drama to the whole. Its innovative use of still photography in this manner has been cited by Ken Burns as the source of inspiration for his so-called Ken Burns effect, a type of panning and zooming effect used in video production to animate still images.
