Keiller’s latest sees his shadowy researcher Robinson embark on another tour of England. Keen to cure the world of ‘a great malady’ (symptoms include the banking crisis, global warming, war in Afghanistan and Iraq), Robinson sought – or so we’re told by an ex-lover (Vanessa Redgrave) of the now deceased narrator of the first two films – to communicate with ‘non-human intelligences’ determined to preserve life on Earth. Keiller’s witty, revealing script weaves together philosophy, the arts, history, politics, economics, science, agriculture, architecture and much else, even as surreal, mysterious and beautiful images, imbued with a deep love of the natural world, remind us of what’s at risk. Timely indeed. (Geoff Andrew)
