The film's music coordinator and sound designer Bones Howe began working with musician Michael Boddicker on the film's theme music and sound effects, as they had worked together on the soundtrack for Get Crazy. Boddicker was Howe's first choice to write and perform the film's score. Boddicker had just won a Grammy Award for his song "Imagination" on the Flashdance soundtrack. In addition to composing the score, Boddicker also produced the alien sound effects, while Alan Howarth was hired to create the sounds of the 8th Dimension.
