Iron Sky (Blu-ray release 2012-10-2) says Nazis went to the moon to hide in 1945, built a lot of spaceships that look like UFO, and return to invade Earth in 2018.  I’m ok with this concept, but there are too many problems in the script.  Comparing the virus nonsense in Independence Day ID4 (1996) to this movie, ID4 made much more sense.  To make things worse, this movie is incoherent.  However, I like the political satires, and the space battle – there exists too few movies with space battles.
