“I first took an acting class from Terry Knickerbocker more than 25 years ago. Since then I have worked with him on every film and stage role I’ve done. Nobody’s better at what he does. Terry is incredibly intuitive and full of ideas that are usually outside the box. His sense of what is truthful is like a laser. I depend on him. He’s invaluable to me and I don’t know what I’d do without him.”
