You do not have to go to film school!
But you should still read all the filmmaking books, watch all the films, surround yourself with others who share your interest, find mentors who will answer your questions, get access to equipment, work on low budget sets for free, etc. Harder than it sounds.
There is definitely no "one right answer" for this, but Jason Kohl's book should be the first thing anyone reads before going.
Gear doesn't make movies. People make movies!
The headline ("The Explosion Will Be Larger than Anyone Claims. Frame Accordingly.") can be universally applied to every area of filmmaking.
The lighting set up will take longer than anyone claims. Schedule accordingly.
The producer will make claims about how things will go. Make back up plans.
The boom will drop lower than expected. Frame accordingly.
Universally good advice.
Watch the video! Great work Mr. Britt.
Expect great things from him. Behind that "doom and gloom" is his unrelenting drive to finish the film.
