The costumes in the film opening are based on research of costumes from other post-apocalyptic films like The Book of Eli to represent people struggling in a new world. The film opening challenges typical post-apocalyptic film ideologies by not including zombies and using natural disasters instead of zombies as the cause of the post-apocalyptic setting. Wide long shots of open space are used to reinforce the idea of natural disasters and show the desertedness of the world.
