I gave a lot of support (and pledged towards) the Kickstarter campaign last time and was tremendously disappointed that it didn't make its funding goal.
This time around, any money you pledge will go to the team behind this, that's the nature of Indiegogo and I'm very happy with the decision the producers made to go down this path.
Support this campaign. I will be.
From everything I've seen, read, and every conversation I've had... This appears to be THE DFW film to support.
You can pledge at many different tiers, and there are all kinds of different rewards, including a copy of Greg Carlisle's Nature's Nightmare at the $100 level. (Here's my interview with Greg about Nature's Nightmare).
