There has never, ever been a better time to be an amateur film director. And the best way to learn the skills is by making films.

I was a professional filmmaker for almost 20 years before my move into VR, and I can assure you I didn't have a lot of cinematic skill when I started :)

You can cheerfully shoot a festival-worthy film on a modern smartphone. If you want to go a bit higher-end you can rent all the kit needed to outfit a professional two-week shoot for a few grand. You'll still need to find people to cast and crew, but that's a solvable problem.

It's a terrible time to be a professional filmmaker, because of distribution woes, but if you want to make films and you have another job (and you're not terribly worried if they don't get distribution beyond some festival showings), there has never been a better time in the history of the medium to do it.
