I love how people think that only movies are what make an actor. Murray is trained in the theater, and yes he has had the fortune to perform in film and television as well. Has even won an academy award. However his career has not fizzled away. He performs throughout the world in theater and film. If you live in NYC you know what I mean. People constantly wonder "what happened to so and so?" and here we are seeing them on billboards and reading thier reviews in the NY Times. They are acting. Just because it isn't on celluloid doesn't mean that they have fizzled. He isn't going to be in film after film because he is not merchandise, like many of the other "hollywood" actors are.
