"Despite having only a budget of 7.5 million Euros, Iron Sky has the look and
feel of a film made with thirty times that. As with Star Wreck, Timo Vuorensola
and his producing partner Samuli Torssonen demonstrate that their forte is high
quality visual effects. The ones produced here rival the work being produced by
Industrial Light and Magic, Weta Workshop and other leaders in the field. The
scenes as we see a flotilla of swastika-emblazoned zeppelins going into Earth
orbit dragging meteors behind them and then opening up to launch hundreds of
flying saucers from their insides have a dazzling detail and clarity that makes
you gasp. The battle scenes between Nazi UFOs, fighter jets, Earth ships and
the launching of the massively armoured Gotterdammerung are spectacular. The
scenes where the Gotterdammerung fires its missiles and blows an edge of the
Moon up in a massive detonation or the final shot pulling back from the Moon
around the Earth to follow the tiny trails of nuclear missiles crossing the
curve of the Earth are stunning shots. Equally good is the production design,
most of the sets being conducted virtually and digitally inserted behind the
actors where the crew take their leaf from Sky Captain and the World of
Tomorrow

(2004) and create an exquisite retro-world based on 1930s era technology.
