When auditioning for an acting part, there are certain things that you should keep in mind. First of all, remember the basics: be sure to have a good posture, good diction, and a creative portfolio. Some headshots and general information about yourself and the training you had would be sufficient. Also, try to take a firm grip of yourself in order not to get too nervous because of the stress.
Most important, you should be well prepared for acting auditions. Meaning, you have to know your lines. It would make a bad impression to stare aimlessly at the floor, trying to remember the lines you forgot. Knowing your part allows you to work with your character and improvise a key factor when it comes to acting. You have to come across naturally, and that implies getting familiar with your character. In order to do that, you must know the script.
Sometimes you’ll get the whole script sent over. You have to read through it carefully and try to understand your character. Try to speculate about its background, if it’s not given, and figure out the character’s emotions and how to convey those feelings through your acting. If you have just a fragment of the script, the one that should interest you the most, go through it several times and try to read into the character as much as you can.
You may come across several ways in which you could read and interpret the part. Be sure to pick one which allows you to be very comfortable and natural when playing. Don’t try to show off and try as hard as you can to give your best. Also, never forget to have faith in yourself. Be confident. If you are, come what may, you’ll handle it.
