Iron Sky is a 2012 Finnish-Australian-German comic science fiction action film [first in franchise].
The United Nations assembles to discuss the extraterrestrial Nazi threat...becouse Nazi space lords are keen to eradicate "Untermensch".
To add a spin into plot, there is the presence of large tanks of helium-3 on the Moon, of which the Presidents of Earth nations are immediately trying to claim from Nazis, into their possession, in order to ensure a millennium-long supply of energy.
Most of the names in the movie have a symbolic and often ironic meaning. The plot is referring to several motifs that originate in post-war Esoteric Nazism, such as the symbol of the Black Sun or Nazi UFOs.
