That would be, for me, the audition where, for some reason, we're sitting around not getting anything done, while one guy (who's wearing long sleeves in the middle of July) seems to be getting more and more anxious and agitated, until a friend comes by, they go off into another room, for a few minutes, the friend leaves, and the guy with the long sleeves comes back, very calm and glassy eyed. OK, let's play.....
Pay attention to the other folks at the audition. Some you may not want to hang around with, for one reason or another.
Excellent advice!!
I have mentally cancelled my enthusiasm before based on various cues from behavior and ""Look".
Not personal appearance as much as "look."
You know what I mean.
