This last weekend I watched the director’s cut of Dark City—“a shadowy sci-fi masterpiece,” according to the blurb on the Netflix folder. I didn’t remember the original well enough to notice the difference(s), but this time I was much more interested in how the movie plays with the notions of memory and reality. But it only plays with them. Still, documents have a small role—and artifacts a large one—and there is a character named Mr. Book.
