Actor

This would be you. If you get the part, you'll be able to play other people - and get paid.

Audition

This is what you go on in order to get the part. You prepare your scene, and try your best to be exactly what they want.

Headshot

This is an 8x10 picture of your mug - that's face, not coffee cup. Remember to keep your picture current 

Resume

This is a written copy of any previous acting work you might have done. It's usually one page in length. It lists the roles you've played in movies, TV or plays, your training (if any) and all the special skills that make up your funky self. And yes, special skills include things like juggling and skateboarding.

Call Back

This is what happens after your first audition, if they decide that they'd like to see you again. You'll be invited to audition for the same part again, but this time the director and producer will most likely be present.

Director

This is the person who is in charge of what the actors do, who shapes the story that you end up seeing on the big screen. If a movie had a parent, the director would be the dad - the big kahuna.

Producer

This person (or people) acquires the cash, builds the crew and gets people together. The producer is a problem solver that gets things done. The producer is often the money behind the project, so it's really good if they like you. The producer would be the mom - the other big kahuna.

Agent

This is your representation, the person who acts as your contact with the film company, and they will most likely have gotten you your audition. They'll also negotiate how much money you'll make if you do get a part
