Via MeFi here is an interesting (I think) annotation of a scene from The Matrix Reloaded, in which Neo talks to someone called the Architect. I haven't seen the movie yet -- The Matrix is, for me, a wait-for-video venture -- but this scene, although it sounds a bit spoilerish, didn't spoil much for me at all. At least, I don't think it did. It's a lot of the "You don't understand your true nature" stuff that filled the first movie. But fans might find the annotations interesting.
