Osmosis Jones takes the premise of Fantastic Voyage and turns it into an animated comedy. There are live-action bits, starring Bill Murray, but most of the movie takes place inside Murray's body, where there are animated red blood cell characters and animated germ characters and so forth that illustrate the body waging war against a deadly disease. The movie is a good one. What I like about it is how endlessly creative it is in its visualization of body functions. The stomach, for example, is an airport terminal, where the arrival of foods and medicines is announced over loudspeakers and monitors. And that only scratches the surface. The film's innovation, funny enough in itself, is the springboard for more amusement in the way the animated characters work with it and also in the way they interact with the unknowing outside world.
