The Killer Inside Me stars Casey Affleck as Lou Ford, a sheriff and murderous sociopath. Jessica Alba, Kate Hudson, Bill Pulman, and Liam Aiken co-star. Audiences who have seen The Killer Inside Me, based on the novel by Jim Thompson, tend to point to the film’s graphic and horrific nature. Although, you don’t get a huge sense of that from the sleek trailer. The teaser for Winterbottom’s film emphasizes the suggestion or looming threat of violence, with powerful results. The shot of a gloved hand hopelessly outstretched to a foot is haunting in its simple action.
