All Sisyphus' silent joy is contained therein. His fate belongs to him. His rock is his thing. Likewise, the absurd man, when he contemplates his torment, silences all the idols. In the universe suddenly restored to silence, the myriad wondering little voices of the earth rise up. Unconscious, secret calls, invitations from all the faces, they are the necessary reverse and price of victory. there is no sun without shadow, and it is essential to know the night. The absurd man says yes and his effort will henceforth be unceasing. If there is a personal fate, there is no higher destiny, or at least there is but one which he concludes is inevitable and despicable. For the rest, he knows himself to be the master of his days. At that subtle moment when man glances backward over his life, Sisyphus returning toward his rock, in that silent pivoting he contemplates that series of unrelated actions which becomes his fate, created by him, combined under his memory's eye and soon sealed by his death. Thus, convinced of the wholly human origin of all that is human, a blind man eager to see who knows that the night has no end, he is still on the go. The rock is still rolling.
Lang's most seminal film was M (1931, Germ.) - his first sound feature (bridging the gap between silents and talkies). It was an expressionistic psychological thriller about a child molester serial killer. The pedophile-psychopath was identified as Hans Beckert (Peter Lorre) - his coat back was marked in chalk with the letter "M." He was caught hiding in an attic, and taken to a large abandoned brewery building to stand trial, where he was questioned by a panel of underworld boss-leaders.
