I just hope that this movie won't too ridiculous. I quite liked "Return to Castle Wolfenstein" because of all the fictive elements it had without being too silly about them.

Of course I don't believe in Nazis on the Moon, because I know that they travelled to Aldebaran instead. That's what Iron Sky 2 will certainly be about: The now adult Siegfried and Brunhilde escaped to Aldebaran and beget many children which are transformed into overhuman soldiers due to space radiation. They then run out of subhumans to heat up their houses and need to return to Earth to get new supplies... Something like that maybe.
