After that we went inside the second part of the tour, which was more dedicated to the technical bits of filming. There were creepy masks and wax dolls, beautiful concept art, tons of very impressive sketches and paper models, as well as Diagon Alley and a model of the Hogwarts Castle. It might be silly, but the Hogwarts Castle made me really quite emotional. It was just so beautiful and surreal, and even more so because of the choice of background music.
The tour was everything that I had hoped for and more. It was simply magical. Already, I can't wait to go back again. What I've shown in this post is only a teeny tiny part of what you get to see. Even if you're not a Harry Potter-nerd, I highly recommend going as I'm sure most people would find the details of film-making very interesting!
