Alternate Versions (3)

  • In the original theatrical version, the Mars scenes were tinted pink/red.
  • In 1978, a "Special Edition" was released by Wade Williams with new special effects scenes (shot in color in 1976). This is the version available in USA on video.
  • The Navarre DVD release (as part of a 'triple feature') does not include the new special effects sequences or the pink/red coloring. The Mars sequences are, however, tinted a pallid, sickly green.
