I thought I’d move past linking to more Gone Girl articles, but here we are; it’s that strong of a film. DP Jeff Cronenweth talks about Fincher’s preferred visual style:
I think that, for the most part, the camera is never in a position that would be a typical shot. There are no shots that are ever taken for granted. There’s a purpose behind everything — without getting crazy; obviously certain situations allow you a lot more freedom than other situations, but it always intrigues me that it’s slightly not normal, or not traditional, rather. The camera tends to stay lower; we’re always looking at people in an observational way that allows you, really, to study them and give them an opportunity to express whatever turmoil’s going on in their heads that then reflects in their performances. The camera has movement but nothing is ever moving for the sake of movement, you know? There’s purpose for everything, as opposed to filling in a void in content or our energy by deciding to make some interesting camera moves. The camera moves have a reason.
