 John Lydon's Post-punk group Public Image Ltd ("PiL") was supposed to score the soundtrack for the film and worked on the material with his band mates Keith Levene and Martin Atkins (over the phone, by long distance).In early November 1982 PiL announced the imminent release of a new single, "Blue Water", and a six-track mini album, "You Are Now Entering A Commercial Zone", on their new label, which was supposed to release the unused music for "Copkiller".This did not happen, with the band instead continuing to record a full-length album at South Park Studios.
