From James Cameron, director “Avatar,” “Titanic”:

Received Shadowplay and watched it twice.  Excellent film.  For some reason, maybe because it was animated, I resisted an emotional reaction because I knew that was expected of me.  Cried anyway.  It is a profoundly effecting piece.  I have wrestled with how to tell the story of Hiroshima for many years, and always hoped to make a film on the subject.  What you have shown, which is also true of the story of the Thousand Cranes, is that the event is too horrifying to look at directly.  You need a metaphor.  You found yours and used it brilliantly.  Bravo.  I am recommending your film to friends.
