There is a way in which Hollywood works. It helps to know the mechanics of how things get done. With more knowledge you’ll be a step ahead of those that haven’t given it much thought.
First of all, Hollywood is built on trust. Ultimately, it’s a small town relying on reputation and consistent good work. But there is a process that precedes the audition that you should know.
For instance, if a TV show is looking to add a new character they put a call out through Breakdown services. Daily breakdowns then go through SAG franchised agents and managers. (Usually, it’s the early morning hours that agents go through breakdowns.) Some pick up the phone and call the casting office directly to make a pitch. If there wasn’t a call headshots are submitted.
The casting director will then set up appointments for the actors to come in and read. There isn’t much time in a casting session so it’s very important to be well prepared and ready to work. Remember, you are judged the minute you walk in the room, well before you read the first line. How you walk in, how you carry yourself and the degree of understanding of the character will all make a difference. Try to stay as natural and close to yourself as possible. Make it easy for the casting director to want to call you back. Keep in mind they are looking for your personality along with an understanding of the character.
You may get called back that same day or a few days after. Try to stay within the framework of the initial reading because that is why they want to see you again. If the reading goes well, and both the director and producer like you, there may be more call backs. They are looking for consistency in your reading. (This applies as well to being put on tape.) The more you can stay true to who you are the better chance of them recognizing your talent.
Staying grounded, focused and consistent are sure ways to make the audition process work more effortlessly in your favor. You stand out when you allow your uniqueness to shine within the given context of how Hollywood works today.
