So… Godzilla dances in Invasion of Astro-Monster. He also boxes a little. Unfortunately, the boxing part does little to liven up the last half, which is incredibly tiring. The dancing comes earlier—though not by much, but enough to “help.”
Godzilla doesn’t appear in the film until the middle mark. Instead, the film’s about astronauts Nick Adams and Takarada Akira discovering a civilization of aliens living on a previously undiscovered moon of Jupiter.
Adams and Takarada are both pretty bad, but Takarada is worse. Adams is visibly awful, but he’s trying. Takarada doesn’t try. Not even when he gets to be a scientist for a bit (being an astronauts means you’re qualified for anything).
There’s also the romance subplot. Takarada won’t let his sister marry her boyfriend. Sawai Keiko is fine as the sister, as is Kubo Akira as her boyfriend. He gets slightly better scenes than her; unfortunately, both of them finish the movie as Adams’s sidekicks.
The rest of the acting is lukewarm. Tazaki Jun is pretty good. Tsuchiya Yoshio is terrible as the villain, but it’s probably not his fault. I think his costume inspired Devo; it’s unbelievably silly looking.
But Honda’s direction (in Panavision) occasionally shows he’s fully capable of doing something amazing. His space shots in Astro-Monster, though brief, are phenomenally well composed. Even the later framing is also strong.
Ifukube Akira’s music is excellent; some of the miniature work is quite good.
But it’s an uphill battle—the script sinks the film.
