I know the film isn't released in english. But the original story, the novel was published two times. As The Satanic Mill and The Curse of the Darkling Mill by Otfried Preußler. You have to read the book. It's fantastic.
The Film had world premiere at Toronto International Film Festival 2008.
And I found an english dubbed version of the trailer -> http://www.bavaria-film-international.de/htmls/bfi/index.php?site=program_trailer&id=254&tr=vid5
For anyone who doesn't know the story of this film. Here it is:
The Thirty Years´ War brought much death and destruction to central Europe, and left 14-year-old Krabat an orphan. Lost and devastated, Krabat’s keen survival instincts lead him to a remote valley, where he finds a mysterious mill run by an ominous figure known as the Master. The lure of a safe haven, hot meals and an apprenticeship under the Master is hard to resist... but gradually Krabat uncovers a horrifying secret: the mill is in fact a school of black magic and the Master is in league with satanic powers.
While Krabat and his young colleagues revel in the teachings of the Master, they realize there is a price to pay: complete submission to the Master and even death. After Krabat witnesses Tonda, his closest friend at the mill, perish at the Master’s hands, the fires of rebellion starts raging within the young boy. He realizes that the only way out is to defeat the Master in a duel. In the face of such adversity, Krabat is able to find strength through the lovely Kantorka.
Armed with nothing but courage and their love, the young couple brave the Master and the arsenal of magical powers that make him nearly invincible. But is the power of love alone enough to defeat the power of black magic?
