Good question! I have no idea, but I would love to watch it in English as well. So hopefully somebody will answer soon! :-)
It is such a shame that so many movies here are dubbed in German. I have nothing against the German language and I understand it well enough to understand a movie in, but I believe every movie should be shown in the original language(s) with subtitles. Also, it seriously decreases our options as foreigners living in Frankfurt. Anyway, thanks for sharing your opinion about the movie :-) Did you read the book, by the way?
