What do american people think of when they see a turk?

The Turks I've seen are usually reeeallly good looking. You wouldn't be typecast if you're a really good actor, unless you took a role as a terrorist and was really good at it. You could be someone's love interest. Paul Shenar was part Turkish (and really handsome,) and played a Latin American (Sosa in Scarface) so you may not even be cast as a Turk. Anyway, good luck!
