If you have a smart phone, you're ready to start making movies! :o) Good luck!
With Youtube and the internet the traditional doors to entry are no longer closed. You can make a film that can be seen by every person in the world.
Watch films that inspire you and see how they created them with camera moves, lighting, etc.
“Immature poets imitate; mature poets steal; bad poets deface what they take, and good poets make it into something better, or at least something different. The good poet welds his theft into a whole of feeling which is unique, utterly different than that from which it is torn.” T.S. Eliot
Or in a simplified version “Lesser artists borrow; great artists steal” Pablo Picasso
And finally the latest version "“Good artists borrow, great artists steal.” Steve Jobs
So as you can see... we all stand on the shoulders of those before us.
Go out... create... put it out in the world and keep going!
