Immediately upon the completion of Nosferatu, Werner Herzog set about filming Georg Büchner's play Woyzeck, which he had once considered as a vehicle for Bruno S. before deciding the leading role was better suited to Klaus Kinski's talents. And Kinski definitely shines as the put-upon army private who is continually berated by his captain (Wolfgang Reichmann) and subjected to a doctor's (Willy Semmelrogge) bizarre behavioral experiments. Furthermore, he has fathered a child with a prostitute (Eva Mattes) who hasn't entirely given up the profession, as evidenced by the scene where she entertains handsome drum major Josef Bierbichler (star of Heart of Glass) in her room. All in all, once poor Woyzeck starts hearing voices and having terrifying visions, it's only a matter of time before he does something that he'll regret later. Or rather, he would if he were still in his right mind. With Kinski in the role, it's easy to imagine that he was never entirely sane to begin with.
