Thank you, hon! I'm so glad you found this interesting, and that it accords with what you've found yourself.

I like how you describe it all as a ballet - it's certainly choreographed, even though it can look so random! The whole process is certainly a fascinating one. I think I particularly enjoy how very quickly the crew transform the modern setting into a 'medieval' one, set up the technology, and get ready for filming - and then how very quickly it gets packed up afterwards! :-)
