I will definitely do my next fictional film in 3-D, and I would also like to develop of documentary in 3-D because Pina is a strange, amphibian thing because it had a documentary approach and of course it is a documentary, but what you are filming is in itself fiction—choreography itself is fiction. It’s a strange beast. I would like to use 3-D in a much more conventional documentary and subject, just going on a little more and make something. Werner [Herzog] did that with [Cave Of Forgotten Dreams], but he also was just a rudimentary beginning of what you can do with 3-D. I think it will definitely lift the documentary genre to a whole new level as soon as it can be used economically. But the technology is there now, and you can shoot with cheap cameras. You need an additional person in your crew. You need a stereographer because it is a science in itself, and a DP is completely… I mean lighting a film and operating a camera and taking care of the 3-D architecture is just too much. You need an additional man in your crew, and that’s about it. I think the cost is maybe a few percent more, but that’s not what should prevent people from doing it. I have students now who have started doing it.
