Walter Murch is one of the most famous film editors alive. His films include Apocalypse Now (1979), The Unbearable Lightness of Being (1988), and The English Patient (1996). Here is a talk he gave last year about the art and science of editing, in the context of his latest film which is his first documentary called Particle Fever (2013).

Among the many interesting moments was a description of how he combined film for The Unbearable Lightness, with 1960s documentary footage of the Soviet invasion of Czechoslovakia. Eerie parallels is this footage (25 mins in) with Russia now in Ukraine.
