ALL THAT AND AN IKEA JOKE: I love David Fincher. I loved Fight Club, liked Panic Room, loved Social Network, know I will love Zodiac once I see it (Adam, why didn't you tell me this was any good?), love his signature touches (the dim taupe palette, the heroic credit sequences), and love his furtive sense of humor. Example: In Fight Club, Tyler Durden tells a possibly fabricated story about how he used to work in a theater and splice single frames of male anatomy into the movies so that the audience would receive them subliminally, and then, as Fight Club reaches its climax, Fincher does the same thing. It's just about a frame, barely enough to notice; not enough to interrupt the narrative; plenty enough to insinuate himself, and maybe you, into Durden's japery.
Spacewoman and I have decided, therefore, that Fincher was sharing a little in-joke with readers of his source material when, in The Girl with the Dragon Tattoo, the first thing Mikael Blomkvist does is order a sandwich. The sandwiches! This is an exceedingly violent movie, but there probably are more sandwiches than guns. Well played, David Fincher.
