Good live theater disturbs molecules. You create an energy source around yourself and it alternates between you and the audience. Anybody who sees live theater should come out a little rearranged.
I think there are certain actors that have that kind of energy about them, that taking over a room energy.
I love the chemistry that can be created onstage between the actors and the audience. It's molecular even, the energies that can go back and forth. I started in theater and when I first went into movies I felt that my energy was going to blow out the camera.
