Iron Sky was made with several film producing companies investing n it about 6,5 million euros. In addition to that one million of financing came from the crowdfunding sources, that is fans of the film.
That means: there are several financing organisations involved in the production expecting it to be profitable and wanting to get some interest to their money.
Thus, you see, Iron Sky is no more a shoelace budget movie of Energia production.
The distribution goes therefore on the traditional commercial ways: people must buy tickets to movie theaters to see it. Later I hope there will be an opportunity for me to buy me a DVD or blue-ray copy of the film. The rights to show the film are sold for about 70 countries at the moment. The companies that bought the rights to show the film are also expecting the film distribution to be profitable.
Therefore it is not available free on the Internet.
If the film is successful also financially and that means it is sucessful in the box office, that means we have in the future opportunity to see more productions from these guys who made Star Wreck and Iron Sky. Best way to support the guys at the moment is to see that wonderful Iron Sky in theaters! I have seen it and my recommendations: it is an excellent movie.
Here is a map, where you can see the countries that have distributors of the film confirmed:http://www.ironsky.net/site/film/releasedates/
