UPDATE: The director has pulled access to the trailer. He apparently didn't realize it was public and didn't mean for it to be. He told me he should have more information about the movie soon.
This is absolutely some of the most stunning Seattle Sounders footage out there, the most amazing of which is video of Sigi Schmid's postgame speech after last year's 3-0 loss against Real Salt Lake in the Western Conference semifinals. If this six-minute trailer is any indication, this will be an absolutely spectacular film. Still not sure when it might be coming out, but we'll definitely keep you apprised of any developments.
Should be noted, the audio is NSFW.
Lots of other interesting videos on their site, too.
