Some time ago, I met with a producer who was raising money for his zombie movie online. He was allowing people to buy "producer packages" in exchange for a financial contribution to the film, and these packages could also be given as presents.
You can check out his project Invasion of the Not Quite Dead here. He also offers contributors the chance to be a zombie extra in the movie.
Meeting AD Lane got us producers thinking. Does crowdfunding really work? If anything, it seems suited to a small budget.
So once our scripts are developed, we're going to do some research and give it a shot.
