The Book of Eli is post-apocalyptic sci-fi with a drifting hero (with an initial undisclosed purpose) travelling west, and he is embodied by none other than Denzel Washington as the title character. This is a violent and graphic film, with gray skies and brown deserts, desaturated from realistic colors to the point that some of the visuals look black & white. In an early deadly encounter as Eli faces off some homicidal scavengers underneath a bridge, it is filmed in high contrast so the actors are pitch-black while the desolate landscape serves as backdrop.
