If you loved Godzilla vs. Gigan, try Godzilla vs. Megalon
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 Jun Fukuda, and they both carry the playful mood tag, and they sit in Action / Adventure / Science Fiction territory. If that's the register that drew you to Godzilla vs. Gigan, the second film will land in a comparable space — through a different lens.

What Godzilla vs. Megalon is
You're an inventor whose robot is hijacked by a vengeful underwater kingdom. They unleash a monster to destroy the surface world, using your creation to guide it. The fate of humankind hangs in the balance. Fukuda’s film is pure kaiju energy, a Saturday-afternoon special with heroes good and evil.
