Trivia / Dragon Ball Z: Lord Slug

• Acting for Two: Kenji Utsumi voiced Shen Long again and also voiced Slug in his elderly state. He was not credited as the latter however.
  • Naoki Tatsuta once again voices both Oolong and Hire Dragon with the two sharing a small amount of screen time together.
  • In English, Christopher Sabat voices both Piccolo and Shenron plus provided the vocals for Icarus.
  • James T. Fields voices both the cowardly stammering Gyoshu and the raspy vicious Kakuja.
  • Brad Jackson reprises Oolong and briefly voices the ill-fated henchmen of Slug's, Zeeun.
  • Mike McFarland again voices Master Roshi and Yajirobe for their brief appearances in the movie.
• Dueling Dubs:
  • Speedy Video had released an English dub around 1999 on VCD in Malaysia as "Super Saiya, Songoku," with a voice cast that could barely speak English.
  • AB Groupe produced a dub in 2001 as "Super Saiyan, Goku" with English-speaking voice actors in France for the European market. This dub was based off the French dub.
  • Funimation dubbed the film in 2001 at their in-house studio in Dallas featuring a localized script and a replacement musical score by Bruce Faulconer with Evan Jones, and many licensed songs from bands like Deftones, Finger Eleven, Disturbed, American Pearl, and Breaking Point. It was released to VHS and DVD in both edited and uncut versions. An alternate version of this dub was released in 2008 on DVD and Blu-ray with the original score.
• Early Draft Tie-In: The entire concept of the film was to showcase Super Saiyan, releasing a scant ten days before its first manga appearance and being in development when the transformation was only ever implied to exist. Consequently, the filmmakers had no idea what it might look like, and the result in the film is more or less their idea of what it would be, based on Toriyama's vague suggestions.
• The Nth Doctor: After Slug has his wish for eternal youth granted, in Japanese, his voice changes from Kenji Utsumi to Yusaku Yara.
• Recycled Script: Not only is Lord Slug a carbon copy of Demon King Piccolo, but the movie itself takes some cues from Dragon Ball Z: The Tree of Might, with a space pirate coming to Earth and, due to how beautiful the place is, changing it completely (Turles having the Tree of Might suck the life energy of the planet; Slug terrafreezing the planet for his people).
