These should be obvious, but it's surprising how many actors make a bad impression with something as simple as inappropriate behavior. It can knock you out before you step into the ring. Remember: Casting directors already have the job — you don't. So you need to prove yourself to them, not the other way around.

Other suggestions we heard from CDs: Avoid unnecessary chit-chat. Don't linger in the room for too long after you read. Stay away from using most props. And avoid making physical contact with the casting director during your audition.

A feeling of desperation is another sure way not to get a callback. Never view an audition as nerve-wracking nightmare, or make it look that way. Consider each audition an opportunity: A chance to perform for an audience — albeit a small one. Or walk into the audition saying, "No matter what happens, I'll do the best I can today."
