This horror tale in the spirit of E. T. A. Hoffmann was an outspoken revolutionary story. In it, as Janowitz indicates, he and Carl Mayer half-intentionally stigmatized the omnipotence of a state authority manifesting itself in universal conscription and declarations of war. The German war government seemed to the authors the prototype of such voracious authority.
Subjects of the Austro-Hungarian monarchy, they were in a better position than most citizens  of the Reich to penetrate the fatal tendencies inherent in the German system. The character of Caligari embodies these tendencies; he stands for an unlimited authority that idolizes power as such, and, to satisfy its lust for domination, ruthlessly violates all human rights and values. Functioning as a mere instrument, Cesare is not so much a guilty murderer as Caligari’s innocent victim. This is how the authors themselves understood him. According to the pacifist-minded Janowitz, they had created Cesare with the dim design of portraying the common man who, under the pressure of compulsory military service, is drilled to kill and to be killed.
The revolutionary meaning of the story reveals itself unmistakably at the end, with the disclosure of the psychiatrist as Caligari : reason overpowers unreasonable power, insane authority is symbolically abolished. Similar ideas were also being expressed on the contemporary stage, but the authors of CALIGARI transferred them to the screen without including any of those eulogies of the authority-freed “New Man” in which many expressionist plays indulged.
A miracle occurred: Erich Pommer, chief executive of Decla-Bioscop, accepted this unusual, if not subversive, script. Was it a miracle? Since in those early postwar days the conviction prevailed that foreign markets could only be conquered by artistic achievements, the German film industry was of course anxious to experiment in the field of aesthetically qualified entertainment. Art assured export, and export meant salvation. An ardent partisan of this doctrine, Pommer had moreover an incomparable flair for cinematic values and popular demands. Regardless of whether he grasped the significance of the strange story Mayer and Janowitz submitted to him, he certainly sensed its timely atmosphere and interesting scenic potentialities. He was a born promoter who handled screen and business affairs with equal facility, and, above all, excelled in stimulating the creative energies of directors and players.
