I love rehearsing because in rehearsals there are no mistakes, nothing is wrong, some things apply or lead you to focus on the character and the things that don't apply are equally valuable because they lead you to towards what does.
Now, the language that had grown up and formed itself on those principles is what one is dealing with, and the problem is to bring a work of art in that medium into another medium formed on different principles and heard and understood in a different way.
