From the official website: http://www.indiegamethemovie.com/
"Indie Game: The Movie is a feature documentary about video games, their creators and the craft. It examines independent game developers as a way to understand the medium and the theory behind video games. Throughout, the film focuses on the human side of the creative process, and the connections between game and game-maker."
