So you've auditioned an actor, and they nailed their lines during their initial audition. So what do you do when they step in the casting room for their callback session? Do you feed them the same lines to validate your initial experience during their first audition, or do you give them new content to play with?
Our suggestion? Both.
While you'll want to validate your judgement when assessing the actor's first audition by having do another run-through during callbacks, you'll also want to throw some new material at them to get a range for what they can do when presented new material in a casting room, on the fly.
After all, you're conducting callbacks, which means that you've got a lot more time to audition each and every actor during this audition. Based on how important callback castings are, you may want to even alert your casting facility that you're casting callback session will be running long so that you can take your time in making critical casting decisions.
So to summarize: Have the actor repeat their initial audition, having the actor do something special off-script, but also, take your sweet time in the casting room to make sure you're picking the best possible cast.
