A behind-the-scenes video has appeared from
Harry Potter and the Order of the Phoenix where David Yates (Director) and Stuart Craig (Set Designer) talk about how they came to design the set for the Ministry of Magic. They even talk about how they visited the muggle equivalent to contrast them.
Quote:
We thought it would be fun to place it beneath the muggle ministries, so we went to Whitehall and the Ministry of Defence.
The video can be seen
