In Detroit and many other places around the country, this audition is one that is typically set up by your agent. You should aim to arrive at least fifteen minutes early to your audition. They may have paperwork for you to fill out beforehand, but more than likely they already have your headshot and resume that your agent sent over. Though just on the off chance that they don’t bring two with you, sometimes the auditioner likes to have a hard copy to reference.
Before the audition you may have received an email from your agent with a side (copy, script), take the time to memorize this. You can’t have a piece of paper in front of your face while you are auditioning and you would look absurd if you even tried. You may receive a copy at the audition, make quick work of memorizing the first and the last lines, so you can still perform well without the script in front of you, this allows for the auditioners to see your face clearly at the beginning and at the end of your performance. Do not let people reading the same script as you be something that takes your spirit down a couple of notches. The casting director or auditioners already have in mind the images of how the actor or actress will look and appear and you already fit that image at this point so just make a good impression and make the best out of every audition.
