It's PAL, but that may not be true, either way it's amazing this is being released. This will be the first silent feature on blu, no? It claims to feature restored high deifinition versions of bothe the movietone version and the recently discovered Czech print, which looked quite spiffy in comparison to previous versions on DVD. Add tot hat the already existing features which will be included, the 68-page "booklet"(more like a book!) and rare outtakes, original trailer, commentary, etc. An incredibly exciting release, for sure.
