Didn't know there was a new Studio Ghibli movie out until I chanced upon the soundtrack on an anime review site.
It's called Gedo Senki (Tales From Earthsea), and is roughly based on U. LeGuin's Earthsea novels. It is, however, not directed or produced by Hayao Miyazaki, but rather, by his son, Goro - his first work as director of a feature film. The film's music is composed by Tamiya Terashima.
It's an enjoyable anime, as I've come to expect from Studio Ghibli. Unlike the recent Ghibli films, no (or limited) use was made of computer-generated effects. This has resulted in a far less 'flashy' film; coupled with the rather laid-back use of colours, one could be easily forgiven for thinking this was an older Ghibli film, rather than the most recent one. The animation quality is still excellent, however, as are the sound effects and the music.
