Anne Frank is depicted writing her final diary entry on August 4, 1944 immediately before the Achterhuis is stormed by the German uniformed police. In reality, she wrote this entry three days earlier.
The failed assassination attempt of Hitler is heard on the radio and mentioned by Margo and the next scene is identified as May 1944 but the failed bombing that injured Hitler was in July 1944 so it is not in the correct sequence.
