US astronauts disturb a Nazi moonbase, and the Nazis launch an expedition to earth to pick up a computer tablet to power their final invasion using a super-fuel mined from the moon.
Hectic spoof sci-fi that's totally illogical, full of plot holes, and yet turns into a good satire. Effects are done really well, plenty of other movies referred to (including the music), and closest in spirit probably to Flash Gordon from 1980.
It does hurry itself along, so the pace is good but at the expense I think of decent character based gags. The acting was good, particularly the females - the lead was very charming, and the president and her sidekick were mean and brisk.
A final plus is that some US reviewers don't like fun being poked at their awful political system.
Overall not great, but it was refreshing.
