To match the careful costume design, Anderson also tends to set his movies in large multi-room buildings (or vehicles) that suggest the dreamy reality of a theatrical set. His most famous creation in this regard is probably the Belafonte, Steve Zissou's boat, which contains a research library, a laboratory, a sauna (with a Swedish masseuse!), and an editing room: It could be suggestive of Zissou's fractured brain, or it could be a visual allegory for the process of making a movie, or it could just be really cool-looking.
It's a spiritual sibling to the Tenenbaum house, to the titular train in The Darjeeling Limited, and the titular Grand Budapest Hotel, which is rendered in several different time periods that microcosmically suggest the protagonist's coming of age across the transformative 20th century.
