Unfortunately, many of those who knew Hitler during his youth like to give examples of how Hitler's thinking or actions at that time would later contribute to his later climb to power. Hanisch, although usually honest and forthright (he remained in Austria even after Hitler's armies marched in years later), is one of them. Hanisch claimed that Hitler went to see "The Tunnel," a motion picture about a political agitator who rises to become a popular leader. According to Hanisch, the "movie" greatly impressed Hitler and he "told me [Hanisch] the story."1 However, Bernhard Kellermann's book, Der Tunnel, was not published till 1913. By the time the movie was made and released (1915),2 Hitler had left for Germany. Hitler, however, may have read the book (he later stated that Der Tunnel was one of the "major reading experiences of his youth,"3) before he left Vienna. Hanisch may of known of Hitler's enthusiasm for the book and confused it with the movie.
