I'm not in it for long; it's only a couple of seconds of footage, shot at PAX in Seattle in... 2013, I think. But it's specifically of me. I remember the game I was playing at the time, even if I'm not sure of the year; I don't remember the camera crew.
Anyway, here's an article in The New York Times about the documentary. Here's a review. I wonder how it did at SXSW?
Hat tip to Randy Mac Kay for pointing it out to me. Funny thing is, at first mention, I thought it was from a different movie, one that I do know I'm in. This film? I had no idea. SURPRISE!
