In the crazy world of film schedules, it's necessary to be able to turn one set into another, especially if you'll never need the first set again. So what you see here will eventually become the Queen's breakfast room and bedroom at Buckingham Palace. For now, though, it's the interior of Villa Windsor. Here, the Windsors [played by Alex Jennings and Lia Williams] host a photo shoot and party to watch the Duke's niece get crowned—the Windsors are always hosting. As so often, the trickiest thing seems the easiest: in this case, getting the right shade of blue to sit with the gold to sit with the panels. The Windsors are pretty sure about themselves, that they have the greatest taste, while the family back in England are a bunch of heartless vulgarians to be despised and pitied. The challenge is to convey all this without excess.
