I want a simple equation designed. As an actor I get my work based on a few variables. 1. My headshot photograph - is it good or bad (suitable or not)?
2. My CV/experience/training - is it right for the role
3. The audition - can I act?
If a casting director likes my photograph, then they look at my CV, if they like both then they may ask me to audtion.
At the audtion I either do well and get the role of I do badly and don't get the job.
If I get the job I get paid
The casting director is the one who makes the decision.
Can you lay this out in an equation?
