My wife and I work as a team and together we have backed about 20 projects.
We back projects for multiple reasons. We have been a part of 2 successful Kickstarter Campaigns and are currently in the middle of a third right now (
https://www.kickstarter.com/projects/pu ... ers-anchor) so we Completely Understand how much work goes into them and how much is means to have people back a campaign. So, we try to repay the favor when we are asked to.
Also, as Actors and filmmakers ourselves we see the benefit in backing films as a way to connect with other like minded people. The last film we backed we ended up getting contacted by the director and asked to audition, then booked roles in the film.
I will say that no matter how much we want to back something, if there is NOT an interesting incentive it makes it very difficult for us to back it. Getting something out of it is one of the great things about Kickstarter so we LOVE seeing people get creative with their incentives.
