When you hear these phrases, it means a Casting Director is prepping a scene for a future work date and is checking your availability. If you are available, please mark your calendar to limit work conflicts. “First avail” means that the Casting Director cannot hire you until production looks at your picture submission and approves the look. It’s typical not to get this information until the day before the shoot.
If you are offered another job on the same day, we ask that you give us the courtesy of the “first right of refusal.” Just let us know so we can inform our show. They may option to offer to hire you first. You are still able to be hired elsewhere if we are unable to confirm a booking for you.
