I'm not sure how long it's been available, but my buddy just told me last night that the film is available for streaming through Netflix. Here's the description of the documentary from the site:
Get up close and personal with the blood, sweat and tears of competitive mixed martial arts with this documentary, which follows welterweight hopeful Jon Fitch as he prepares for the fight of his life against perennial UFC champ Georges St-Pierre.
Believe it or not, I'm not dedicating the day to sitting in my underwear watching it on loop, so if anyone has seen it or watches it later on, feel free to let me know how it was in the comments. Just thought some people might be interested in it, as it's been mentioned in MMA news off-and-on for quite a while, but was never available for viewing until now.
