On the DVD: disc one includes an interesting, if a little flat, director?s commentary. Better is the isolated score with a superb and fascinating commentary from composer Elliot Goldenthal. Other options allow you to access more information about the film. The menus are clear and feature full CGI effects and specially created sequences. Disc two is where you will find the real meat, with literally hours of documentaries and technical promos to plough through covering every aspect of the filmmaking process, along with music videos and an alternative opening sequence. You can re-edit a short sequence from the film and there?s also a wealth of DVD-ROM material offering the complete screenplay and an interesting tour of Square Pictures, makers of the film. Features like the FHM-style photo shoot of CGI heroine Aki give an indication of the target audience for this movie. Add all this extra material to the superb picture quality--which almost leaves you convinced that you are watching a live action movie--and crystal sharp sound and you have one of the most technically impressive discs to hit the market so far. Any DVD buff will need this just to prove that the format is a worthwhile investment.--Jon Weir
