If you're new to acting, you'll quickly notice that the industry has its own vocabulary.

Casting directors, agents, acting coaches, and filmmakers often use terms that may sound unfamiliar when you're just getting started.

Understanding these words can help you feel more confident during auditions, communicate more effectively, and better understand casting notices.

Fortunately, you don't need to memorize hundreds of definitions.

Learning the most common acting terms will give you a strong foundation as you continue building your acting career.

In this guide, we'll explain some of the most important acting and casting terms every beginner should know.

Why Learning Acting Terms Is Important

Every profession has its own language, and acting is no different.

Understanding common terminology helps you:

Read casting notices with confidence.
Communicate clearly with casting directors.
Understand audition instructions.
Feel more comfortable in rehearsals.
Build confidence as your acting career grows.

You don't have to know every industry term immediately.

Start with the basics and continue learning as you gain experience.

Audition

An audition is the process of performing for casting professionals to be considered for a role.

Auditions may take place:

In person.
Through self-tape submissions.
Online using video conferencing.
During callbacks.

Every audition is an opportunity to demonstrate your skills and professionalism.

Casting Director

A casting director is responsible for helping choose the actors who will appear in a production.

They review submissions, organize auditions, evaluate performances, and recommend actors to producers and directors.

Casting directors are looking for performers who best match the needs of each role.

Callback

A callback is an invitation to audition again after your initial audition.

Being called back means the casting team would like to see more of your performance or determine how you fit with other actors being considered.

While a callback is encouraging, it does not guarantee you'll be cast.

Slate

A slate is a brief introduction given before your audition.

Depending on the project, you may be asked to state:

Your name.
Your height.
Your location.
Your agency, if applicable.

Some productions may also ask you to turn to each side or provide additional information.

Sides

Sides are the pages of a script provided specifically for an audition.

Rather than reading the entire screenplay, actors usually receive only the scenes relevant to their audition.

Reviewing your sides carefully helps you understand the character, relationships, and emotional context before performing.

Cold Read

A cold read is an audition in which actors receive the script shortly before performing, sometimes only a few minutes in advance.

Casting directors use cold reads to evaluate how naturally actors interpret material with limited preparation.

Monologue

A monologue is a speech delivered by one character without interruption.

Actors often use monologues:

For acting class.
During auditions.
To practice performance skills.
When building confidence.

Choosing age-appropriate and well-prepared monologues can help you showcase your abilities effectively.

Improv (Improvisation)

Improvisation, often called improv, is acting without a scripted scene.

Instead of memorized dialogue, actors create conversations and reactions in the moment.

Improv helps actors develop:

Active listening.
Creativity.
Confidence.
Quick thinking.
Adaptability.

Many acting classes include improv exercises because they strengthen performance skills that carry over into scripted work.

Scene Partner

A scene partner is another actor performing with you during a scene.

A strong performance depends not only on delivering your own lines but also on listening and responding naturally to your scene partner.

Great acting is built on genuine interaction rather than simply waiting for your next line.

Blocking

Blocking refers to the planned movement of actors during a scene.

A director may tell you:

Where to stand.
When to walk.
When to sit.
Which direction to face.

Following blocking helps actors stay within the camera frame or stage design while supporting the story.

Mark

A mark is a specific spot where an actor is expected to stand during filming.

These positions are often indicated with small pieces of colored tape on the floor.

Hitting your mark accurately helps ensure:

Proper camera framing.
Correct focus.
Consistent lighting.

Learning to find your mark naturally is an important on-camera skill.

Principal Role

A principal role is a character with scripted dialogue or a significant part in the story.

Principal actors usually appear in the credits and have greater responsibilities during production than background performers.

Background Actor

A background actor, sometimes called an extra, appears in scenes to create a realistic environment.

Background actors usually do not have speaking lines, but they play an important role in making scenes feel authentic.

Examples include:

Restaurant patrons.
Office employees.
Students in a classroom.
Shoppers in a store.
People walking through a city.

Featured Background

A featured background performer receives more camera attention than a standard background actor.

Although they may not have dialogue, they are often clearly visible and may interact more closely with the main action.

Non-Union

A non-union actor is not a member of a performers' union.

Many beginner actors start by working on non-union productions to gain experience before deciding whether union membership aligns with their career goals.

Demo Reel

A demo reel is a short video compilation showcasing an actor's best on-camera work.

Casting directors often review demo reels to evaluate an actor's performance style and screen presence.

As beginners gain experience, they can gradually build a stronger demo reel with footage from completed projects.

Headshot

A headshot is a professional photograph used when submitting for acting opportunities.

It should accurately represent your current appearance and help casting professionals imagine you in a variety of roles.

Your headshot is often the first impression you make during the casting process.
