This episode was designed to have echoes of the Original Series story "The Devil in the Dark".
	According to Maurice Hurley, just about everything that could go wrong with this episode did, and huge chunks of script had to be re-written the day before shooting.
	Walter Gotell (Mandl) played General Gogol in the James Bond movies.
	The line "bags of mostly water" is spoken in the song "My Definition of a Boombastic Jazz Style" by Dream Warriors (about 02:40 into the song).
