Brad Pitt wants the music for "World War Z" to be much more than a footnote.
Pitt says that while making the zombie flick, out on June 21, he wanted the film's soundtrack to have songs reminiscent of those made for "The Exorcist."
Enter Muse, which recorded the instrumental track "Isolated System" for the movie.
Pitt says the pairing of the British band with the film was "nice kismet." He says the band members were actually reading the "World War Z" book when they were recording their latest album, "The 2nd Law."
Muse was at the London premiere of the film on Sunday, performing a special outdoor concert at Horse Guards Parade park for the occasion.
