ACTUALLY Arabs rarely play Arabs. Normally, Indians or Mexicans play Arabs because most Arabs aren’t down to be type cast as terrorists 24/7. So even when the roles are prejudice AF, they still don’t cast the correct ethnicity. That’s Hollywood for ya.
If they do end up casting someone Arab For Aladdin (btw, I’m rooting for any Iraqi bc that’s where Agrabah is supposed to be), it’ll probably be the first time Arab actors play the leading roles in a major motion picture. So they better get this right.
