Das Tagebuch der Anne Frank ("Anne Frank's diary") is a 2016 film directed by German Hans Steinbichler.
 It tells the story of Anne Frank, the Jewish girl who went into hiding with her family in Amsterdam and became a victim of the Holocaust.
 The film is based on Anne Frank's famous diary.
 The world premiere was held at February, 16 in a special presentation for young people during the 66th Berlin International Film Festival.
 It was listed as one of eight films that could be the German submission for the Best Foreign Language Film at the 89th Academy Awards, but it was not selected.
The Anne Frank tree (Dutch: Anne Frankboom or, incorrectly, "Anne Frank boom") was a horse-chestnut tree ("Aesculus hippocastanum") in the city center of Amsterdam that was featured in Anne Frank's "The Diary of a Young Girl".
 Anne Frank described the tree from The Annexe, the building where she and her family were hiding from the Nazis during World War II.
Annelies Marie "Anne" Frank (] ; ] ; 12 June 1929 – February or March 1945) was a German-born diarist.
 One of the most discussed Jewish victims of the Holocaust, she gained fame posthumously following the publication of "The Diary of a Young Girl" (originally "Het Achterhuis"; English: "The Secret Annex" ), in which she documents her life in hiding from 1942 to 1944, during the German occupation of the Netherlands in World War II.
 It is one of the world's most widely known books and has been the basis for several plays and films.
Anne Frank: The Whole Story is a two-part mini-series based on the book "" by Melissa Müller.
 The mini-series aired on ABC on May 20 and 21, 2001.
 The series starred Ben Kingsley, Brenda Blethyn, Hannah Taylor-Gordon, and Lili Taylor.
 Controversially, but in keeping with the claim made by Melissa Müller, the series asserts that the anonymous betrayer of the Frank family was the office cleaner, when in fact the betrayer's identity has never been established.
 A disagreement between the producers of the mini-series and the Anne Frank Foundation about validity of this and other details led to the withdrawal of their endorsement of the dramatization, which prevented the use of any quotations from the writings of Anne Frank appearing within the production.
 Hannah Taylor-Gordon received both Golden Globe and Emmy Award nominations for her performance as Anne Frank, while Ben Kingsley won a Screen Actors Guild Award for his performance as Otto Frank, Anne's father.
 It is revealed in the miniseries that the cleaning lady of Opekta betrayed Anne and her family.
Laatste Zeven Maanden van Anne Frank (English title: "The Last Seven Months of Anne Frank") is a 1988 Dutch television documentary directed by Willy Lindwer about the last seven months in the life of diarist Anne Frank.
 Seven different women, who were fellow prisoners of Anne Frank in the Westerbork transit camp, and the Auschwitz and Bergen-Belsen concentration camps, gave interviews about Anne's last months in this documentary.
 Among them are Hanneli Goslar, Anne's childhood friend and fellow prisoner in Bergen-Belsen, and Janny Brandes-Brilleslijper, Anne's fellow prisoner in all three camps.
 Both women, who were cell mates with Anne and Anne's sister Margot, are believed to be among the last known people to have seen Anne alive.
The Shooting Party is the ninth novel by Isabel Colegate published in 1980 that won the 1981 WH Smith Literary Award.
