^^^you said you went in a small movie theatre right? And someone was playing the movie off the DVD player? Well, it's not only against the law for JUST Anime movies, it's against the law for American, Italian, French, German....etc movies as well. Usually before a movie there's that big FBI WARNING and it talks about public display of the movies for commercial purposes and reproduction...it's for every movie

it's possible they may release it in select independant theatre's approved by Japan and SE
