The Internet has really democratized ideas. There are no real gatekeepers any more, because if you have a great idea, and you put it online, people will find it and it will get in front of who it needs to get in front of.
It's up to the courage of the filmmakers to make art in cinema, not just business. John was rejected by studios, he borrowed money and did movies with his own money. You're either courageous or not. You have to find a way.
