This visual essay analyzes shots from the film Shutter Island that set up themes of mystery, danger and confinement. Quick cuts between shots add confusion, while dim lighting and rain establish a dark and ominous tone. A close up of a stranger's hand leaves their identity unknown. Bars, gates and handcuffs seen in shots suggest the film will be set in a prison-like institution where people feel trapped. Red walls and a shot of a foot dragging a gun hint at danger and crime. Dark exteriors and falling snow put the audience on edge.
