THE DIARY OF ANNE FRANK
1959

Title: The Diary of Anne Frank
Year: 1959 
Director: Zach Snyder

Three Oscars for this one!

Historical background:
Wee Anne Frank and her family lived in hiding in Amsterdam 1942 - 1944 to escape Nazi persecution but the Holocaust caught up on them.

Millie Perkins is Anne Frank.

IMBD mentions that Audrey Hepburn was offered the role but Ms Hepburn declined as she herself saw the Nazis live and in 3D in the Netherlands herding Jews onto boxcars like cattle. Too much too soon.
