At the time of this writing, it is Scorsese's last feature to be shot entirely on film. Choosing the 2.35:1 aspect ratio, he uses the frame to exaggerate the interplay between the vertical and the horizontal, compressing the film's spaces until the screen is suffocated, and escalating the sense of foreboding and claustrophobia... Shutter Island sculpts its contours from the psychological and spiritual torment of its main character, creating a theater of cruelty.
