Third in a series about WWII leaders from Russian director Sokurov, who also did Russian Ark (though I haven't seen either of the previous works in this sequence), about the renunciation of divinity by Hirohito after the defeat. Within the palace, all the ritual continues unabated, in complete contrast to what we saw earlier in the year in Downfall.
All the dialog is in the appropriate language, with the Japanese and American as appropriate, and the print I saw was subtitled in English.
Amusingly, having caught the Sunday lunchtime showing, this was, in effect, a private performance.
