The document discusses the soundtracks of four post-apocalyptic films and how they establish tone and atmosphere. It notes that the soundtrack of "I Am Legend" is slow-paced to highlight isolation. "The Walking Dead" opening has an eerie but not too fast soundtrack to create intrigue. "The Hunger Games" soundtrack has a similar pace to "The Walking Dead," indicating a fight for survival. The soundtrack of "The Road" is also very slow-paced to enhance feelings of isolation in that film. Studying these soundtracks helped inform the choice of soundtrack for the author's own post-apocalyptic film opening.
