Non-linear narratives are among the favourite concepts of several post-modernist scholars. The online world in which we live certainly makes non-linearity quite apparent, often equating it with freedom. There’s also a playful dimension here. Although such a movie is quite different from “Choose your own adventure” gamebooks (what we knew, in French, as «livres dont vous êtes le héro»), there’s a clear connection between a non-linear movie and those games/narratives.
Does sound like an interesting project. The film’s website explains some of the technical details (including the fact that it can’t be played on Mac OS X computers).
