Leni remained unwilling to apologize for her past. She just claimed that she was misunderstood and distant during those years.
Fritz Lang could have had her job. He fled to America instead. Everyone has choices.
Leni Riefenstahl was honored by the Academy at the Oscars when they showed her picture among those who had died in the previous year.
Refenstahl is extremely influential on the way movies look. You can't avoid her. To not consider her an important film artist is to put one's head in the sand. Same with Eisenstein.
