I was reading books about the Nazi presence not only in Argentina, but all over Latin America, and time and after time this information would come up.

When I wrote Wakolda at first I wasn't conscious that I was writing about something so close to or that had so many similar elements with XXY. It was just after I was done writing that I noticed it. I think both teenagers in each film have many similarities, and Mengele is the extreme version of the plastic surgeon in XXY. Both stories definitely have several ideas connecting them.

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.

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.

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.

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.

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.
