Why was this film made? Because someone talked Greenaway into trying to go mainstream. By this time, he had already made some of the most adventuresome films in history. This simple confection is sandwiched between `Zed and Two Noughts' and `Drowning by Numbers,' both of which are complex, intelligent, risky, erudite.
I can only imagine that he thought he could finance his serious work with a commercial success. Some might tag this as an accessible Greenaway film, but I hardly think it is Greenaway at all. Nor is the remarkable composer Nyman present.
All that remains are some lush compositions, studies in photographing monumental architecture, and these are pleasant enough. A subtext is fascist perfidy in architecture and the film takes a critical (visual) stance on Roman architecture. See here how all the buildings are from the emperors or Mussolini. No church architecture here which must have been a conscious omission for simplicity.
Everything about the physical fabric portrayed is dehumanizing, especially as compared to the containing space of the skin. As an architect myself, I can appreciate the message. It is a clever conceit, but it pales, utterly fades away, in comparison to his best: `The Falls,' and the `book' films.
