It is adapted from "Panopticon", a film within a story from the 2001 novel number9dream by David Mitchell, with Martin Freeman starring as a prison psychiatrist, and Tom Hollander as his patient.

[3] Dr. Williams (played by Martin Freeman) is hired by Governor Bentley (Simon Griffiths) to work as a prison psychiatrist after "The War in the East" has produced a doctor shortage.

Williams attempts to show her Belgium in an atlas but finds it is gone and replaced with a body of water called "Walloon Lagoon."

Back at the prison, Williams is baffled by the lack of any evidence of Belgium, but refuses to believe in Voorman's divinity.

He then states that he made humans to be imaginative purely to amuse himself and he finds wars like the one in the east “comedy gold”.

Voorman mockingly mimics a psychiatrist tone of voice saying if he cannot have a conversation without shouting he will terminate the interview.
