If you loved OVERLORD: The Sacred Kingdom, try Overlord: The Undead King
A bridge between a film you've already seen and one most people haven't. Overlord: The Undead King has roughly 4.6× fewer votes than OVERLORD: The Sacred Kingdom — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Naoyuki Ito, and they both carry the epic, foreign gem mood tags, and they sit in Action / Adventure / Animation / Fantasy territory. If that's the register that drew you to OVERLORD: The Sacred Kingdom, the second film will land in a comparable space — through a different lens.
What Overlord: The Undead King is
You wake to find yourself undead in a world that won’t log out. The NPCs ache with feelings you never coded. Now a skeletal sorcerer, you rule allied creatures by sheer will. The simulation fraying, you hunt the truth behind the shutdown. The game keeps changing, monsters kneel, people scream.
