Tyler Perry made his own shit and essentially has complete control. And has production companies like Marvel paying him to use his Studios. So it can be done, and others are following suit.
50 Cent has a production studio
Tyrese has a production Studio
Will Smith has a production company
Denzel has a production company
Michael T Jordan has a production company
All Black men, most of whom collaborated with or were mentored by Denzel.
Etcetera....
So it's happening, the general public may just not be aware of who owns what behind the scenes.
I know.
The public needs to support these projects more.
And these new projects need to ensure they hire black folk at all levels of support.
