The United States release of this film includes a written introduction that other cuts of the film do not have. It contains more information regarding the keys and bomb. This can be viewed on the Vestron Video release and the Laserdisc that followed it. The German DVD contains the only Widescreen cut of the film. As a special feature; this intro is included.
The Japanese laserdisc is an alternate cut of the film in many ways. Being 10 minutes longer, the film focuses less on finding their fathers (while having an adventure) but more on the adventure itself and finding women. With more narrations by Phillip, this is more of an adventure-noir film. The film has many different and alternate scenes including the death of Rusty, the removal of the sewer monster, less of the Disco Punks and alternate ending.
