But, I cannot even get anyone to read my script that I wrote, and I am a White guy, it is supposed to be easy for American White guys. And as an actor I could not even get a job on "The Young and the Restless."
Um, Tony?
No, it is not "supposed to be easy for American White guys."
It's
EASIER for them, overall.
And do you know how many people want acting jobs versus how many get them?
https://www.statista.com/statistics/548587/roles-minorities-hollywood-movies/Minorities get a bit more than 13% of acting jobs in American movies. Lower percentage of scripts.
Your problem is not your color. It is not these foreigners getting their scripts.
Amistad was a brilliant idea and a brilliant production. But it took luck, too, to get it seen. Ask your South African friend not for a role in his movie but if he can (a) help you tighten your script and (b) get it seen.
It might be that you just need some luck and connections, whether your script is brilliant or if it sucks. (Plenty of sucky scripts get turned into movies!)
