What Are Sides in Acting? How to Prepare Them

Sides are the few pages of a script you audition with, usually one to five pages from one or two scenes. Casting sends them through Actors Access, Casting Networks, or by email, often as watermarked PDFs. Here is how to read them, prepare them in the time you actually have, and rehearse them even when the PDF won't copy and paste.

Most guides to sides treat getting the file as a solved, invisible step and jump straight to craft advice. This one covers the part nobody explains: the watermarked, copy-protected, or photographed PDF that won't open, won't print, or won't drop into a rehearsal tool. We build Line Echo, which reads those pages for private rehearsal, so we spend real time on it here.

What are sides in acting?

Sides are the specific pages of a script you are asked to perform for an audition, pulled from the full screenplay or play. Instead of the whole script, you get the scene or two that casting wants to see, so you can prepare a focused, bookable audition rather than an entire show.

What a side looks like on the page is simple: a scene heading, the character names in capitals above their lines, the dialogue itself, and the occasional stage direction or parenthetical. Sometimes casting adds a short note at the top about the character or the scene's context. The format is plain because its only job is to give you the words and who says them.

The name is a leftover from the Shakespeare era. Paper was expensive and full scripts were rarely copied, so each actor received only their own lines plus the cue lines that came just before them, written on a single sheet, a "side". The whole play stayed with the stage manager. The economy is gone but the word stuck.

How long are audition sides, and do you have to memorize them?

Most sides run one to five pages, and you usually need to be off book enough to stay present, not word-perfect. Commercial and TV sides tend to be shortest, while film and theatre sides can run a little longer, but a single audition scene rarely stretches past a few pages.

On memorizing: the working norm is "familiar, not flawless." You want the lines solid enough that you can lift your eyes off the page, listen, and react, because a read glued to the paper reads as unprepared. But being rigidly word-perfect can backfire in an audition, where casting may ask for an adjustment and you need to shift without falling apart. Aim to be deeply comfortable rather than robotically exact, and always follow the breakdown if it names a specific expectation. If you want a method for getting there fast, our guide to memorizing lines in one night and the line memorization test both help.

Where do sides come from?

Sides come from casting, almost always through one of a few channels: Actors Access, Casting Networks, Breakdown Express, or a direct email. Which one depends on how the project was posted and who is representing you.

Actors Access and Breakdown Express are run by Breakdown Services (Breakdown Express is the casting-director-facing side, Actors Access the actor-facing portal). Casting Networks is a separate, competing platform with an equivalent feature set. In practice, the important rule is the same across all of them: sides are released to you when you receive an audition invitation, not before, and access is often restricted to the invited actor. Files uploaded to a role are not handed out to actors or reps until they are attached to an actual invitation (Actors Access / Breakdown Express help docs, checked September 2026).

Why are audition sides watermarked?

Because the watermark is a traceability measure. It stamps your identity onto every page so any copy that leaks can be traced back to the person it was released to, which discourages sharing sensitive, unreleased material.

Casting Networks states it directly: casting directors can enable a watermarking feature that "ensures that the documents are traceable and helps to prevent unauthorized sharing," stamping the email address of the logged-in user across each page of the PDF in a light gray, diagonal watermark (Casting Networks support, checked September 2026). Actors Access calls its equivalent "Secure Sides," which watermarks each page with the recipient's username and the date and time they downloaded or viewed the file (Actors Access / Breakdown Express, checked September 2026).

That has one practical consequence worth understanding: to make the watermark stick, these PDFs are often flattened into images. The page becomes a picture of text rather than selectable text. So even though nothing stops you from reading your side on screen, the file frequently won't copy and paste, and many rehearsal apps cannot read it at all. This is the exact wall most actors hit, and it is why the watermark and the "won't copy" problem are really the same problem.

Two things to be clear about, because they matter. First, the watermark stays on your copy. It is meant to, so never try to remove it. Second, rehearsing privately is precisely what sides are for. Reading your own watermarked side to prepare is the intended use; posting, forwarding, or redistributing it is not.

Sides won't open or print?

If your sides won't open, the fix is almost always your pop-up blocker. Actors Access's own troubleshooting is blunt about it: you need to allow pop-ups for actorsaccess.com (or breakdownexpress.com if you are a talent representative), because the file opens in a new window that a blocker silently kills (Actors Access help docs, checked September 2026).

A few more that clear most cases:

• On mobile, check your Files app. A phone browser often downloads the PDF silently. Look in the Files or My Files app rather than assuming the download failed.
• Save to Files or Drive, not the browser tab. Once it opens, save it somewhere stable so you are not re-triggering the pop-up every time you want to rehearse.
• Some sides are view-only by design. Casting can set an online-only option that removes print and download entirely, and a "confirmed only" restriction that opens the file only after you confirm attendance or submit. If there is no download button, that is a setting, not a bug. And once watermarking is on, Casting Networks stops putting a direct link in the notification email; it says "Log in to view attachments" instead, routing every view through an authenticated, watermarked session.

How to prepare audition sides: a 24-hour plan

Most sides arrive with about a day's notice, so here is how to spend it. The principle is simple: do the thinking early, spend the last stretch on your feet running it against the other lines.

The one step that quietly makes or breaks a side is the 6-hour one: running it out loud against another voice. Memorizing alone teaches you the words but not the timing, and timing is what makes a scene feel alive.

How to rehearse sides when you have no one to read with

When there is no one to run the scene with, an AI scene partner reads the other roles and waits for your cue, so you can drill the timing solo. Because casting sides are so often watermarked or photographed, the thing that matters most is whether the tool can actually read the page. Here is the flow in Line Echo:

1. Upload the PDF or a photo

   Upload your side as a PDF, or just photograph the pages with your phone. The text is read off the page even when it is a watermarked, image-based PDF or a photo, which is exactly the case ordinary copy-paste and many apps fail on. Your watermark stays on your copy; the text is read only for your private rehearsal.

2. Choose your role and the other voices

   On one setup screen, pick the character you are reading and assign a voice to each of the others. Choose voices that fit so the cue lands with real intention, not a flat read.

3. Run the scene

   Play it. The AI reads the other roles, listens while you say your line, follows along, and comes in with the next cue when you finish. Repeat until the rhythm is in your body.

Honest limits on page count: the free plan reads up to 3 scanned or photographed pages per upload, which covers most single-scene sides; paid plans read more per upload (10 on Working Actor, 20 on Studio). Free practice scenes run with no account at all; uploading your own sides needs a free account.
