Fantastic Four

In January 2015, Marco Beltrami was hired to compose the film's score. Philip Glass was also hired to work on the score with Beltrami. Additionally, American hip-hop recording artist El-P scored the end credits of the film. To promote the film, Kim Nam-joon, known as Rap Monster of the Kpop group Bangtan Boys, and American recording artist Mandy Ventrice, worked on the digital single "Fantastic", which was released alongside the South Korean run of the film. In July 2015, Beltrami attended the 2015 San Diego Comic-Con International to discuss scoring the film. Beltrami described the score as "eerie" and "mysterious", landing it in a "musical territory leaning towards fantasy." The film score was released on August 14, 2015 by Sony Classical Records.
