Bill Murray has reached a point in his career where he has that something called screen presence without actually having to act. He dozes on a couch, he shifts his gaze a centimeter or two, in an extreme moment he may actually roll his eyes. And the audience watches raptly and chuckles appreciatively. As he tries maturity on as a persona, that clown from Caddyshack and Ghostbusters has acquired something on screen that approaches real gravity. He’s been making interesting films, and maybe he has it in him to do something really audacious, like Buster Keaton in Film, but less obtuse. I hope so.
