If they actually ever finish this film I'll buy it.
There's no harm in pledging/buying ahead of time. If enough money isn't raised by Jul. 20, 2011 your credit card doesn't get charged - you lose nothing. If enough money is pledged are credit cards get charged and we get the movie.
More then worth it in my book. I've made a pledge and i encourage everyone else to as well. The way i see it i would have never become a computer programmer without the Amiga so i owe it way more then what i pledged.
