This black comedy, a co-production between Germany, Australia and Finland, centres on the notion of a Nazi colony established on the dark side of the moon in 1945 and planning a 2018 invasion of an America where Sarah Palin is president. Udo Kier brings a characteristic nastiness to the Nazi leader of the Fourth Reich, and the retro technology is amusing. But the jokes are spasmodic, as satirically weightless as playing golf on the moon.
