soul of the first one." Noonan also claimed to be "relaxed" and enjoying himself on set, where "everyone was incredibly nice," and found Kershner able to adapt with many location and script changes during shooting. Effects Phil Tippett returned from the first RoboCop to do the visual effects for the sequel, this time leading all the effects units. RoboCop 2 was Tippett and Kershner's second collaboration, after Tippett worked at Industrial Light & Magic for The Empire Strikes Back. Most of the RoboCop 2 design was done while Hunter was signed as director. RoboCop suit designer Rob Bottin, although not overseeing the process like in the first film, returned to produce a new suit for the second film. The first suit was dark chrome using metal flake and various green, purple, and gold colors to create a look made iridescent and steel-like by Jost Vacano's fluorescent lighting; however, since Mark Irwin replaced Vacano for cinematographer and used conventional lighting, the second film suit (although using a black base like the other suit) looked light-bluer, so iridescent colors were more directly applied with powder. Thanks to a bigger budget, the effects team had more time to paint and polish the suit, which led to Bottin's desired "show car" look he couldn't achieve in the first. With a lot of planning and fastener hunting, Bottin also built all parts of the suit to come on and off quickly so that it couldn't decay from the actor having it on too long, which was the case of the first film. Stop-motion and computer animation was used for the final showdown between the RoboCop and RoboCop 2 characters. Music The film score was composed and conducted by Leonard Rosenman, who did not use any of Basil Poledouris's themes from the first film, instead composing entirely new themes and leitmotifs. The soundtrack album was released by Varèse Sarabande. The glam metal group Babylon A.D. released a song called "The Kid Goes Wild", written by members Derek Davis, Vic Pepe, and Jack Ponti. The song is played in the background in the middle part of the film, and it was also used to promote the film. The group created a music video featuring RoboCop targeting the band and having a shootout with some bad guys (footage of the film was also used). Release Marketing To promote the film, RoboCop made a guest appearance at WCW's pay-per-view
