Wolf D Prix has form in cutting-edge cinematic kitsch – his Decon cinema in Dresden is a crazily leaning crystal eructation that at least has an appropriately dramatic dynamism. The film-festival cinema in the South Korean city of Busan is in a more parametric vein, and boasts ‘the world’s largest cantilevered roof’ – a nice bit of 1920s-style gigantism, but what a roof. According to the architects, ‘The team drew inspiration from the Renaissance and Baroque era cupola, the roof of Oscar Niemeyer’s house in Rio de Janeiro as well as the sculptural roof of Le Corbusier’s Unité d’Habitation’: a dog’s dinner of influences that – perhaps thankfully – never makes it to the table. No doubt it was meant to swoop and hover but instead it looms, a football-pitch-sized lump blotting out the sky. Catwalks hang from it in swoops that add unnecessary distance between the elements, and the whole is clad in metal panels that give it the air of a metastatised out-of-town multiplex. The building houses a 1,000-seat theatre, three indoor screens and an outdoor screen that can accommodate 4,000 viewers.
