Watch FMovies. Using only archive film and a new musical score by the band Mogwai, Mark Cousins presents an impressionistic kaleidoscope of our nuclear times – protest marches, Cold War sabre-rattling, Chernobyl and Fukishima – but also the sublime beauty of the atomic world, and how x-rays and MRI scans have improved human lives. The nuclear age has been a nightmare, but dreamlike too.
