I love it when actors call their body their instrument. Their bodies do amazing things, and we get to watch. Steve Zahn as Wayne Wayne Wayne Jr. in Happy, Texas , letting a realization gradually dawn. Christopher Plummer as Mike Wallace in The Insider , giving it to us straight from the shoulder. Christine Baranski as the thespian in Bowfinger , raising her face skyward in earnest self-absorption.
Actors do it with their bodies.
They are their bodies. Form and content means mind-body duality for those of us lucky enough to be raised Catholic, and therefore in touch with most of the major neuroses of the Western world. Mind-body duality doesn't work for even the most cerebral among us, let alone for actors. Their form is their content. So when Janeane Garofalo says she had breast-reduction surgery for professional reasons, the way that someone in another line of work would try for an A in a key course, or dress for success, or serve on a program committee, I buy it.
