Conversely, the removal or distortion of dual audio work signals imminent threat and the collapse of Neville’s control. A key example occurs during the scene where Neville chases his dog Sam into a dark, infested building. Here, Lawrence and the sound designers strip away nearly all diegetic sound except for Neville’s panicked breathing and the skittering of the Darkseekers. The non-diegetic score becomes sparse, replaced by amplified foley effects (the crunch of glass, the creak of a door). This reduction to near-monotrack audio creates a sensory deprivation effect for the viewer. More significantly, when Neville is forced to kill Sam—the last vestige of his human past—the audio shifts again. Sam’s growls (animal sound) mix with Neville’s sobs (human sound) over a silent, high-pitched tonal drone (non-diegetic). This dual layer of animalistic violence and human grief collapses the distinction between Neville and his enemies, visually and aurally preparing the audience for his later transformation into a vengeful “legend” from the monsters’ perspective.
