The 10th track of American Beauty/American Psycho, “Immortals” first appeared on the soundtrack for the 2014 Disney animated comedy superhero film Big Hero 6. Fall Out Boy was asked to create the song after learning about the movie’s plot in which a young boy loses his older brother to a super-villain. He recovers from his grief by assembling a team of super-heroes, including a robot created by his deceased brother, to apprehend the villain.
