Battle Royale - the original Hunger Games. A class of children are made to fight to the death. But unlike the Hunger Games, this film is properly violent and slightly disturbing. Controversial, but very, very good.
Amazing Grace is another movie I love. I will make movies of this quality, with the realistic sets and costumes, excellent acting, deeply moving story, and powerful message - which is even more powerful in this case, because the story is true.
