This her advice to a actress:
It will all start with the audition. Make SURE you know your script, nobody wants an awkward person standing up there, mouth open with no words coming out. Make sure your emotion reaches every corner of the room. Remember, you are not yourself. You forget everything you are and be who the character is. It's not you playing the character, it's you speaking. Immerse yourself in the character. You are gone, you don't exist.
