The Matrix Trilogy is definitely on my list of Top Ten Web Search Movies. The basic premise? A futuristic war of the worlds pitting folks in the real world against those who are not - and the only way to get into the "imaginary" world by the people in the "real" world is to log on via a Web-like interface. Have I confused you enough? It's a great set of movies, despite how confusing they may sound.
