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.
I had only that one picture, Hitler, the Beast of Berlin, in which I had a part big enough to impress anyone. I tried for better roles over and over again.
There really isn't any limit to the number of people who want a piece of you, and it's all important stuff.
