Iron Sky

In the last moments of World War II, a secret Nazi space program evaded destruction by fleeing to the Dark Side of the Moon. During 70 years of utter secrecy, the Nazis construct a gigantic space fortress with a massive armada of flying saucers. In 2018, an American crewed mission lands on the Moon and encounters the descendants of Nazis who escaped to the Moon in 1945. The Nazis plan to invade Earth and establish their Fourth Reich, but their plans are foiled by an unlikely hero, James Washington, an African-American astronaut who is taken captive and later helps to stop their evil plans. The film features action-packed scenes of space battles, explosions, and invasions, along with a healthy dose of humor and satire.
