When I first saw the news, I actually didn't believe it was true, like some early April Fools Joke.
But a quick check to The SANDS of FIRE Blog (link)

This movie production was started back when Battlefield 2 first came out, so it has been a long time in the works.
Part 1 was just released, and it comes in at a huge 2gigs, so it will take a while to download. I'm getting it through the torrent right now, and am almost done after 2hours and 45 mins. There are some trialers so you can get an idea of what to expect, but the most recent one is from 2008.

Also, they are planning to put up a streaming version, like on Youtube, but it isn't out yet. And the download is a MKV file, which Windows Media Player can't handle. They suggest getting VLC, as do I of course. While your at it, go ahead and make VLC your default media player instead of WMP. You'll be glad you did. If you don't like the plain gray interface, there are a lot of other ones to choose from.
