[Meela]

I had a few images in my head before the films were released. In particular, Bilbo and Gollum, who have been stuck in my head for a long time.

I don't find that the films have changed the way I imagine things in the book. When I read, I find I still have a set of separate images that I can call upon, as well as the images from the films.
In particular, I had very specific ideas as to how Minas Tirith looked. The images of it in the film came as such a surprise, as they were rather contrasting to my own images, so I prefer to revert to my own ideas when reading.
