Stephen Brockmann argues the fact that "Caligari" was filmed entirely in a studio enhances the madness portrayed by the film's visuals because "there is no access to a natural world beyond the realm of the tortured human psyche". The sets occasionally feature circular images that reflect the chaos of the film, presenting patterns of movement that seem to be going nowhere, such as the merry-go-round at the fair, moving at a titled angle that makes it appear at risk of collapsing. Other elements of the film convey the same visual motifs as the sets, including the costumes and make-up design for Caligari and Cesare, both of which are highly exaggerated and grotesque. Even the hair of the characters is an Expressionistic design element, especially Cesare's black, spiky, jagged locks. They are the only two characters in the film with Expressionistic make-up and costumes, making them appear as if they are the only ones who truly belong in this distorted world. Despite their apparent normalcy, however, Francis and the other characters never appear disturbed by the madness around them reflected in the sets; they instead react as if they are parts of a normal background.
