I am very aware that playwrights, particularly good ones, have a intention for everything they write. Language and punctuation is used specifically, and most of the time actors can find wonderful clues about character in the rhythm and cadence of the language used.
For me to have the opportunity to stay with one character for, God willing, a long period of time, is really exciting.
The (Sir Arthur Conan Doyle) stories were great, for one. The thing that makes him a remarkable character is how he can withstand all of these different interpretations and different styles and, that's what makes a classic character a classic character; they keep coming back and you see them in a new way every time.
With big, emotional roles it's very easy, especially if you've grown up in the American school of acting, to exploit your own pain. You have to be careful about that, because 9 times out of 10, your pain is not appropriate to the character.
