Well, in the “real world,” there’s always prescreens of sorts. Casting directors choose who to see and who not to see from agent submissions for a limited number of slots. Even at open calls or EPAs and ECCs, actors are often “typed out,” meaning they look at everyone and allow only those that they feel fit the types they are seeking audition. No one’s ever guaranteed a chance to be seen. Getting in the door is an accomplishment in and of itself.
