Production began in early 2006, and the production team took their teaser trailer of the film to the 2008 Cannes Film Festival, seeking co-financiers. The team signed a co-production agreement with Oliver Damian's 27 Films Productions. "Iron Sky" is one of a new wave of productions, including "Artemis Eternal", "The Cosmonaut", "A Swarm of Angels", and "", produced in collaboration with an on-line community of film enthusiasts, creating participatory cinema. At Wreck-a-Movie, a collaborative film-making web site, the producers invited everyone interested to contribute ideas and resources to the project.
