A German horror-film director has caused protests and revulsion with his upcoming film about the horrors of the Holocaust.
Uwe Boll, who has been described by some as the "world's worst film director" and a "schlockmeister", said he felt it was time to show the Nazis' crimes in their "full horror" in his up-and-coming film ii Auschwitz.
His aim is to allow audiences to finally grasp the "real, everyday truth" of the Nazis' atrocities.
You can watch a showrt trailer on YouTube but users must prove they are 18 before watching the clip.
In the excerpt, the 45-year old filmmaker appears as an SS officer outside a gas chamber inside which Jewish prisoners are suffocating as they hammer in vain on the locked door.
Other scenes show prisoners being loaded into burning ovens and having their teeth pulled.
Critic Sophie Albers wrote in the German Stern magazine: "The words Auschwitz and Uwe Boll in one breath rightly leads one to fear the worst," adding that the film provoked "outrage, confusion and panic".
Boll said in an interview with Die Welt it was "high time" to make a film which showed the "real Auschwitz".
He said that audiences had for too long been softened by "special story films" about the Holocaust "like Life is Beautiful or Schindler's List".
He said such films no longer had the ability to reach young people and that it was his duty as a German to make the film as a way of confronting the past.
"Every German is obliged to ensure that the Holocaust is not forgotten," he said.
"For a director like me who is known for his explicit depictions of violence, it's my duty to use precisely this talent to show people the atrocities of the Nazis."
