But things such as 'Harry Potter', all I can do is shape my character, seek the director's approval on that, and basically take it from there. Professor Flitwick in 'Harry Potter', I kind of defined how I saw him from reading the book, and luckily that matched up with the director's vision.
After years of practice, I can walk into a bookstore and understand its layout in a few seconds. I can glance at the spine of a book and make a good guess at its content from a number of signs.
