Iron Sky is a science fiction comedy being produced by several film makers collaborating from around the world(for more info click here).
Plot(from the official site):
Towards the end of World War II the staff of SS officer Hans Kammler 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, the Nazi invasion is on its way and the world is goose-stepping towards its doom.
