This is what it all boils down to: do you own it? Are you truly the owner of what you’re saying? Too many actors borrow their ideas, never really owning them. You need to own what you say. Appreciate the subtle difference between borrowing an idea and actually owning that idea.
Let’s say, tomorrow morning someone who works for Greenpeace talks to you about their organization. You didn’t really know much about Greenpeace, but upon hearing about their latest endeavor it strikes a chord. You feel yourself well-up with emotion about their cause, and the more you listen, the more it affects you. Suddenly, you have taken on a new point of view; their newest crusade has become very important to you. You now own that point of view. Now, when you share your thoughts on Greenpeace with someone else, you’ll naturally be more persuasive than an actor who is pretending to care.
Identify your character’s point of view and make it your own. Allow it to be important to you the same way you would in real life. Own it. Don’t act like it’s important to you. Don’t pretend to care by trying to make it sound like you do. That’s how phony people behave. As an actor, you must never “borrow” your character’s point of view. You must always “own it”.
