It is very possible but too many black actors wanna suck on the tit of Hollywood. I mean you can purchase a DSLR for less than 1000 bucks, you can purchase a 4K camera for less than 4000 bucks. Tyler Perry makes the shyttiest films in Hollywood but he's also the richest guy. You can put together a full length feature film, that's professional for under 100K and I know some of those black actors you see on movies and TV can pitch in a couple thousand each but they don't.
Honestly they probably can but there is a reason why they aren't has something to do with fear of the machine but the concept is too simple for people to not follow up on it.
