Well, you never know. Probably not since it's a demo, but even so, Square Enix games always have Japanese subtitles that are easier to translate than Japanese speech, even though it would still take a long time for me! But it's not really necessary to know what their saying; I mean I'll be so excited to get to play it after hearing about this game for years.

Oh, if you're talking about the movie having english subtitles, I believe it does.
