If you loved Dragon Ball: Curse of the Blood Rubies, try Dragon Ball Z: The World's Strongest
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.

Dragon Ball: Curse of the Blood Rubies

Dragon Ball Z: The World's Strongest
What they share
Both films are directed by Daisuke Nishio, and they both carry the playful mood tag, and they sit in Action / Animation / Science Fiction territory. If that's the register that drew you to Dragon Ball: Curse of the Blood Rubies, the second film will land in a comparable space — through a different lens.
What Dragon Ball Z: The World's Strongest is
You train in solitude, always striving to improve. But an old enemy returns with a vengeance, seeking the strongest body on Earth. The heroes face a bio-engineered nightmare. Nishio's film arrived at the height of Dragon Ball mania, and its villains reflect anxieties of a technology-obsessed era.
