I remember when I was at the first showing of 'John Dies at the End' at Sundance, and I was talking to some of the people in the standby crowd who were outside and didn't have tickets. They were just waiting in line to see if they could get in. It was this whole gang of die-hard sci-fi wacko people, and they were just fantastic.
