I find that’s one of the great things about acting-you have the opportunity to stand in somebody else’s shoes. Each character faces a dilemma in her life, and as an actor you’re able to step into that character’s skin, look through her eyes. You leave transformed, a different person, because once you live a little bit of someone’s life, it changes you.
For almost every character I've played in the 43 years I've been working as a professional actor, I've found parts of myself. We are all bipolar in the tiniest essence of what it is. We are all multiple personalities, in a sense, and to be healthy mentally, I think, learning what those multiple personalities are and inviting them in your life is really important.
