I've never submitted a film through a lottery system, but I have submitted my band's EPK to several music festival lotteries.
It cost me more money than I wanted to spend for a blind submission. It was also frustrating because there was no reason given for rejection. Just, thanks for your money!
My biggest takeaway from this video is that I need to create a kingdom.
My biggest worry is time. Due to career and family obligations, filmmaking has been more of a dream than a hobby - certainly not my primary focus. My goal is to change that.
