3D is a naff cinematic gimmick right? The toy du jour for dollar-eyed film execs and publicity hungry arts companies: "the first ever 3D sculpture show" and so on. It's been used, abused and discredited, a flash-in-the-pan fad like Cuban heels: enough already.
Or, maybe, it's the most artistically important development in film since Technicolor? Could it be that 3D technology will be for filmmakers, what the discovery of perspective was for the great artists of the renaissance? That is, understanding that depth of depiction opens up new possibilities for depth of expression.
Two new films, by two great German auteurs show what can be achieved with this much-maligned technology. Werner Herzog's documentary Cave of Forgotten Dreams, about the Chauvet cave paintings in the South of France and Wim Wenders's Pina, his tribute to the choreographer and dancer Pina Bausch, has changed the view of many 3D sceptics who can now see the point.
