Visible crew/equipment: Number 6 enters the room with the huge globe, and we "follow" him around a map table. As the camera passes the table, it films its own shadow falling across the map.

Chosen answer: 1) It's never made entirely clear, but it seems that the government, Six's employers, are involved. 2) Because they wanted to know why he resigned. 3) It's never revealed, although many fans assume that Six is really John Drake, McGoohan's character from the prior show Danger Man. McGoohan has, however, denied that this was the intent and there are some notable differences between the characters. 4) It's never revealed, although, as, in the final episode, Six and his companions are able to drive to London, it must logically be located within the British Isles. 5) No details are ever given as to who has ultimate authority over the Village.
