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.

I'm completely surrounded, not only my father, but also my three brothers, and Sergio, my husband, all four of them work in film. Some are writers, or directors, or cinematographers, all of them. I'm surrounded by men that make films, so much that at some point I felt there was no more room in the family for another filmmaker.For many years I was only working as novelist or writing screenplays for others to direct.

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 What I think is that despite this historical references, Wakolda or The German Doctor is a very intimate story.

In terms of my father, if you have 4 children that work in film, then there certainly was a happy, positive influence from him because none us became an accountant.

In the case of my second film The Fish Child (El Niño Pez), I had written the novel about 5 years before I made into a film. In the case of The German Doctor I had published the novel a year before I started writing the script, I even had another project to shoot. But I had this idea of the powerful cinematic language from the novel that I couldn't let go of.

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.
