On 11 February 2009 , it was announced that the film would star German actress Julia Dietze , while the Slovenian industrial music group Laibach would be recording the soundtrack . Appropriately enough for a film about Nazism , the orchestral soundtrack incorporates leitmotifs from the operatic cycle '' Der Ring des Nibelungen '' and other operas by Richard Wagner , a composer whose music was favoured by the Nazi leaders . The national anthem of the Nazis from the Moon ( " Kameraden , wir kehren Heim ! " ) has the tune of " Die Wacht am Rhein " . During the 2010 Cannes Film Festival , '' Iron Sky '' signed a co-production agreement with the Australian production company New Holland Pictures , which brought Cathy Overett and Mark Overett as co-producers of the film
