Seen playing on a television screen in this episode is the BBC's production of A Christmas Carol (1977), featuring Sir Michael Hordern as Scrooge and John Le Mesurier as Marley's Ghost. Shot in color, on videotape, the footage appears to be 'broadcast' in black and white. Even more bizarrely, the voices of Hordern and le Mesurier (both English actors, speaking English) have been overdubbed in English by other actors.
Noh's full name is given as "Demetri Fordice Noh". His birthday is February 17th, 1977.
The stairs behind the Persian restaurant in Hong Kong is the same set that was used in episode 2.1 of Castle (2009).
