With his fair hair, pale skin and faint voice, Truman Capote cast somewhat of a ghostly appearance. So does the stark winter countryside portrayed in “Capote,” the 2005 film that examines the creation of the novel “In Cold Blood.” The spectral nature makes sense, since the novel, and the film, deals with a quadruple homicide. As Capote becomes infatuated with the murderers, the rural Kansas setting, painted in long-distance shots and moments of ambient sound, harbors the ghosts of the murdered, so that we don’t become too infatuated ourselves. It’s a brilliant device, moments of art within a creepy story.
