In general, even if I'm dealing with a historical subject, I begin with invention rather than investigation, because I need to understand what is going to be the voice or the tone of the story.

Wakolda or The German Doctor is a very intimate story. It is the story of a teenage girl and the way she falls in love with a monster. It is the story of a hunt and of a seduction.

When I started writing the script I thought that maybe someone else would direct it, but then I started to fall for it so much that I left the other project and I put all my time on The German Doctor.

Doctor Mengele is such a powerful character historically, as powerful as Nazism itself, so these subjects always tend to be the protagonists. What I think is that despite this historical references, Wakolda or The German Doctor is a very intimate story.

The Mapuche are our indigenous people from the south, the Patagonia. They are a vey wise and luminous ancient cavitation, which is completely opposite to where Nazism was headed. In the novel [Wakolda], the theme of racial purity and the Nazi obsession with it was much more developed.
