This film is the perfect definition of a masterpiece. A good story (not so different from others of the same period) perfectly developed by Lang, restless, intense, beautifully played by the characters, with a memorable end.
I will always remember the image of Henry Fonda (outstanding as ever!) blaming of his fate to Sylvia Sydney just by looking at her and framed by the little window of the visiting room of the prison; it reminded me to the speechless films of Lang where all the dialogues were replaced by the looking of the characters. No words and so much being told: pure art.
