Watch The First Four Minutes Of 'Iron Sky'

Iron Sky, the jokey movie in which Earth is invaded by a Nazi colony that hid for decades on the dark side fo the moon, is finally out in the wild. Or in nature preserves, at least: it premiered at the Berlin Film festival, and then played SXSW in the past week. Reviews haven't been great so far, with The Guardian delivering a real blow: "not terrible, by any means: just not nearly as funny or cruel as its killer premise suggests." For a film based on an outrageous premise and with the promise of real lunacy, that's not a good note.

We've seen trailers and small clips, and now the first four minutes have been released online. The scenes show how a lunar expedition stumbles across a Nazi mining effort on the moon, and leads into the introduction of the massive Nazi base. Check out the clip below to get a better idea of what the movie looks like.

Iron Sky has US distribution, but no date has yet been set.

Towards the end of World War II the Nazi scientists made a significant breakthrough in anti-gravity. From a secret base built in the Antarctic, the first Nazi spaceships were launched in late '45 to found the military base Schwarze Sonne (Black Sun) on the dark side of the Moon. This base was to build a powerful invasion fleet and return to take over the Earth once the time was right.

Now it's 2018, and it's the time for the first American Moon landing since the 70?s. Meanwhile the Nazi invasion, that has been over 70 years in the making, is on its way, and the world is goose-stepping towards its doom. The three main characters of the story are Renate Richter (Julia Dietze), Klaus Adler (Götz Otto), and James Washington (Christopher Kirby).
