The Region A US Blu-ray of R100 is 1.85:1, in 1080p and with DTS-HD MA 5.1 audio. A trailer is the only extra. The 1080p and lossless audio technically give this release the edge but R100 is not a film with vibrant colour or detail and the US audio is reported to be, like ours, front oriented, so I doubt it is worth importing. The Japanese Region A Blu-ray comes with a making of, stage event collection and trailers. The feature is advertised as having English subtitles but I am not sure about the extras.
