If you loved Battle in Outer Space, try The Mysterians
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
Both films are directed by Ishirō Honda, and they sit in Action / Science Fiction territory. If that's the register that drew you to Battle in Outer Space, the second film will land in a comparable space — through a different lens.
What The Mysterians is
Japanese village. Autumn cicadas. A vanished people. Aliens arrive, seeking land and wives after vaporizing a swatch of Earth. A colossal robot erupts, incinerating what's left. Humanity faces a choice: annihilation or subjugation. Honda's paranoid, post-Hiroshima nightmare gets a vivid, widescreen treatment.
