For the past four years Finnish metal band lymystö frontman Timo Vuorensola has been struggling to make his directorial debut Iron Sky a reality. Following the online debut of a teaser trailer in 2008 Vuorensola was able to secure the necessary $8.5 million in funding, a chunk of which was provided by fans who wanted to see the neophyte filmmaker’s dream come to fruition.

Now Iron Sky is completed and preparing for its world premiere next week in Berlin and a trailer for the finished feature has been released. You can check it out here below.
