Iron Sky 1 & 2

Double bill of sci-fi comedies directed by Timo Vuorensola.

In 'Iron Sky' (2012) a group of German scientists send a fleet of Nazi spaceships to the far side of the Moon to set up the Schwarze Sonne military base during the final days of WWII.

Years later, with the base fully complete and having developed a powerful army, the Moon Nazis launch an attack on Earth hoping to conquer the human population.

In the sequel, 'Iron Sky: The Coming Race' (2019), after Earth is destroyed by nuclear war a sparse population of human survivors take up temporary residence on the dark side of the Moon.

When rumours surface about a hidden city in the hollow core of the Earth a small crew of humans go to investigate if it will be possible to reside there permanently.

However, once they arrive they find that the city is populated by the Moon Nazis led by Adolf Hitler (Udo Kier).

If they wish to save mankind they must first defeat Hitler and his army of evil reptilian creatures before it's too late.
