Does anyone have any information on when this documentary is supposed to come out?

I don't know, the updates for the past few months have had loads about go but little about the film. Last relevant bit I read was that they were applying for grants, presumably to help finish the film.

Patience is needed here I think, we (on Kickstarter) paid for a basic movie and they're trying to create something better for us.

According to the most recent Kickstarter update (from Feb. 3), they are assembling the rough cut of the film.
