"No one has it coming," says the protagonist of "The Killer Inside Me," and "That's why no one can see it coming." That nihilistic vision of a meaninglessly vicious universe is the backdrop to Michael Winterbottom's film version of the 1952 pulp novel by Jim Thompson. Casey Affleck chillingly plays deputy sheriff Lou Ford, a quiet, polite young man in a small West Texas town who is a sadist and a psychopath.
In Winterbottom's presentation, Ford is not a split personality or a Jekyll and Hyde character, those favorite movie types. Rather, he is both polite and brutal, gentlemanly and sadistic at the same time. He apologizes when he kills, murmurs endearments as he tortures, and seems totally sincere. Affleck has the boyish good looks and the calm, contained, almost blank quality needed to make his Lou Ford totally plausible.
There Ford, the educated son of the town doctor, is a protégé of the alcoholic sheriff. Sent out to encourage the local prostitute to move on, he falls into a sadomasochistic love affair with Joyce, played by a kittenish Jessica Alba, who soon suggests they run a con on the town's big shot, Chester Conway (Ned Beatty), whose son is one of her devoted clients. Ford has his own reasons for wanting to punish Chester and he comes up with another plan, one that differs from Joyce‘s in a significant detail.
Ford is a serial killer, but interestingly his male victims are dispatched neatly with a shot to the head or they die off screen. Only the women are tormented in front of the camera, so one has to ask, Why? What's Winterbottom's point? Yes, Ford is a sexual sadist, but that's made clear in those bedroom scenes. What more do we learn about him by watching him brutalize the two women at length? Nothing, which brings this film very close to pornography.
