The Score Doesn't Begin Until 2/3 Through The Film
Zemeckis and his longtime composer Alan Silvestri decided not to introduce the musical score until two-thirds through the film in order to highlight Chuck's isolation. By focusing more on the silence and the natural sounds of the island, the viewer feels just as alone as Chuck does. By introducing the theme of the film during Chuck's escape scene, it reinforces a feeling of understated triumph through the simplicity of the melody.
