Dialogue takes place exclusively in the characters' minds, narrated by the actors. This makes it possible for the viewer to witness the characters' deepest emotions that are not spoken aloud. The decoupling of sound and image strengthens the impression of mental isolation experienced by the characters.
Nudity is ever-present in the movie, expressing the sincerity and vulnerability of the characters. It is not used in an erotic manner and makes the characters more palpable to the viewer.
The film was shot with a very modest budget using a standard digital camera. This creates an atmosphere of realism, supporting its writer's intention to connect fact and fiction in a crude yet sentimental way.
