Film is just like music in the educational respect
I think you see more sucess stories without formal education than with
I think this has to do with the fact that it takes a strongly independent thinker to make a great film, and school can only teach you to follow in the footsteps of others.
Do you need to learn where to position your lights, or why not to use a still camera lens on a motion shoot?
well they can teach you that at school, or you could learn it all in 3 months for free
Connections, dont get me started. You need connections inside the locked doors, film school connections can help you assemble a crew, but not much else. They are all in the same spot you are.
The exception is if you can find a dumb trust fund kid, at that point, you can campaign to borrow some of their dad's talents (did you know in Macedonia money was actually called talents?, Ironic from a film perspective)
Then you can be a genius director like Tony Scott, who did so many things right that they gave him 2 wide release movies in a year. Gas pedal stuck for 90 minutes as a plot, I'll never be that good, and 2 released films by Scott and his dad's money proves it. If I was smart enough to think up such complex plots, I'd have 140 million bucks also. That's how the industry sees it.
