As an actor, do you really understand where auditions come from? Who are casting directors actually, and how much power do they have in the overall process. Why are some actors cast before the "open castings" and some cast during the "open castings".
Who actually initiates the audition process, who makes the final decisions, and how can you use that knowledge to help yourself land more parts?
What aspect of your audtion or self tape make the most impact on these decision-makers.
As an actor, if you understand the audition process as it aligns with the different stages of production, it will help you know where to focus your energy, but also help with that horrible feeling of not getting the part you so badly wanted. Once you "see behind the curtain" and understand the machinery, it should strengthen your resolve, your psychology and focus your attention.
