As the son of a Jewish mother who escaped the Holocaust by moving to Switzerland ("at the very last moment!"), Dani Levy has had a lifelong fascination with the Third Reich.

As soon as he could, he moved from his home town of Basel to Berlin and launched an acting/directing career in comedies, but the 52-year-old filmmaker says that it wasn't until he was in his mid-30s that his mother could bring herself to talk about his life in Germany, and ask him how the country had changed.

"When I was growing up, the subject of Hitler and the war and the camps — all of that was strictly taboo in the household," says Levi in a recent interview. "It was strange, because there was absolutely no discussion about it. As a child, I couldn't understand why. Now, I understand that there are no amount of words that could lessen the pain of their memories."
