Werner Herzog has made some incredible films and this exercise in a kind of allegorical mysticism earned its reputation not merely on its merits but because he had the cast hypnotised. We are in eighteenth century Bavaria. The village glassmaker has died and the formula has been lost; the local baron is literally losing his mind because he has come to believe that the ruby glass has magical properties. Everyone else seems to fall into a sympathetic trance-like state. The local seer predicts the destruction of the factory by fire. Some of Herzog’s finest moments are within the first few minutes, with Popol Vuh’s music accompanying beautiful Super 8 landscape imagery; while the last sequence proves that there is a connection between Star Wars and this most interesting of filmmakers – I’m referring of course to Skellig Michael, off Ireland’s west coast, the furthest point in Europe before you get to the US. Herzog adapted Herbert Achternbusch’s story and Joerg Schmidt-Reitwein’s cinematography is splendid. Like most everything, better seen than written about.
