Amongst the items on the props sheet for the episode Dance of the Dead called for, are flags of all nations. I've checked the film, they never used any flag of any nation. The flags used, and waved by citizens of The Village are either plain blue, red, or orange. I wonder why it was thought that flags of all nations would be called for, when to the majority of the citizens of The Village, the outside world doesn't exist!
Be seeing you
