If you loved Heavy Metal 2000, try Hui Buh: The Castle Ghost
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.
What they share
Theysit in Adventure / Animation / Fantasy territory. If that's the register that drew you to Heavy Metal 2000, the second film will land in a comparable space — through a different lens.
What Hui Buh: The Castle Ghost is
Apparently ghosts need licenses too. Hui Buh is a castle ghost who loses his scaring privileges. Now he must get recertified to haunt again.
