castings for adverts, T.V shows and various other jobs. clients sometimes want certain origin, so when they visit the site and look through, they can then see the person and what they look like. It saves me sending for example andrew henderson to a barmitzva when realistically Ethan should do it as he understands the culture
it just makes things easier
Why would a client want a certain origin? Just say, the majority of the people in your country are racist/prejudice against some people and you need to tell them where everyone's from. Don't sugar coat it

Yea..you wouldn't want Andrew Henderson to do a Barmitzvah, what would the people think!?
I've done 3 Barmitzvahs with freestylers of Asian ethnicity and we've never had any problems..
