. . . If you don't try to make it difficult. Sure, there's a small chance that someone else might through a curve ball, but generally speaking, it's rare.
"So you want this with a Dutch accent, the way Kramer would say it. OK...."
Occasionally, it's a good idea to communicate to actors certain things that go on in an audition that will help/prevent you getting the job. These observations change from time to time, some may be repetitive, but they all are worth taking to heart the next time you walk in....
1.) Bring a couple of headshots with you, even if not requested. A casting director recently had a client show up unexpectedly with the director -- both wanted headshots from the auditioning talent. An astounding 75% didn't bring in two headshots. Even more astounding were those who didn't bring in any headshot! The client was not impressed. Telling the client, "Nobody told me to bring one" lands with a thud. [FYI, the person the client gave the nod to, had two headshots.]
2.) Have a great headshot that glows in the dark. You are being evaluated on many different angles. Don't start off from a position of weakness. That is difficult to recover from. Professional actors have professional headshots.
3.) Have your résumé with you, attached to your headshot, trimmed. It doesn't look good in front of those who can hire you to be asking for a pair of scissors to trim, a stapler, or the classic, wanting someone else to download and print out a résumé. We saw firsthand an actor give an audition worthy of possibly booking, but didn't bring his résumé with him and the client had questions at the end of the day. They chose to pass and go with an actor they felt they could trust.
4.) Do your research on the product or service. That helps let you come in more focused. "What's this all about?" to the client is an automatic pass.
5.) Similarly, asking the client who he is and what he does is not cool.
