Leni Riefenstahl: New film tackles the complicated history of the Nazi filmmaker 

Leni Riefenstahl used her considerable talent to create propaganda films for Hitler, but always claimed she didn't know about the Holocaust and lived until 101. She went on photograph Mick Jagger, and get a birthday card from Michael Jackson 

Leni Riefenstahl with Adolf Hitler, for whom she created propaganda films such as Triumph Of The Will. 

Leni Riefenstahl, director of the notorious Nazi propaganda films, Triumph of the Will and Olympia, and one of the most controversial women of the twentieth century, died in 2003. She was 101. In the mid 1960s, Horst Kettner became her assistant, and later her lover. He was 40 years younger than Riefenstahl. They remained a couple until her death.

When Kettner died in 2016, their household in Bavaria was dissolved. Two years later, the filmmaker Andres Veiel got access to Riefenstahl’s estate, over 700 boxes of previously unseen materials, including letters, diaries, private films, outtakes and drafts of her memoirs. It was the start of a magnificent obsession.
