# What to Do When Your Audition Sides Change at the Last Minute

You've had the sides for three days, and you know them. Then, at 9:40 the night before, an email lands from your agent: "Revised sides attached." Two pages are new, a speech is cut, and your last line is different.

The version in your head is now the wrong one. Or it happens in the hallway: someone hands you a fresh scene and says you're up in ten minutes.

The short version: this is normal, and most of your work survives a rewrite. Find out exactly what changed, learn the first line, the last line, and the turn, then the new lines, and plan to hold the rest well. In the room, don't explain or apologize. Below is how to do each step, plus what changes for a self-tape.

## Know that new pages are part of the job

Late changes feel personal, but they aren't. Casting director Marci Liroff writes that her office sometimes gets material from the writers only the day before it shoots, and that scripts keep shifting, sometimes to the point where the first assistant director hands an actor fully rewritten sides on set. That's from her post ["These 3 Mistakes Might Be Ruining Your Chances of Getting Cast"](https://www.marciliroff.com/these-3-mistakes-might-be-ruining-your-chances-of-getting-cast/).

In the same piece she describes actors who say they only got the material last night. Her reply: "So did everyone else." It sounds harsh, but it's good news: everyone is working from the same new pages on the same short clock.

It also tells you what the room is watching. When the pages are new for everyone, the read that stands out is the one that still plays the scene.

## First, find out what actually changed

Before you learn a word, lay the old sides and the new sides next to each other and go through them with a pen. Revisions can look bigger at first than they are. Sort every difference into one of four kinds:

- **Cuts.** Lines removed. They cost nothing to learn; you only need to stop saying them.
- **Small rewrites.** The same thought in new words. These are the dangerous ones, because your mouth will say the old version.
- **New material.** Lines or beats that weren't there before. This is where your learning time goes.
- **A new situation.** A different scene, partner, or even character. Treat it as a fresh read and go back to [breaking down sides](https://www.offbook.com/blog/how-to-break-down-audition-sides).

Then ask the question that matters most: did the **given circumstances** change? If it's still the same person wanting the same thing from the same partner, your homework is intact. Only the words moved.

If the circumstances did change (she now knows the secret, or the scene moved from his kitchen to a police station), spend your first fifteen minutes there, not on lines. Words learned for the wrong situation get relearned anyway.

## Triage the pages: cold, solid, and held

You won't get everything word-perfect by morning, and you don't need to. Sort the lines into three piles.

### Learn cold: the first line, the last line, and the turn

Your first line starts the scene and your last line ends it, and both are moments when your eyes should be on your scene partner, not the page. Learn them first. Add the moment where the scene turns, such as the confession, where looking down would cost you most.

### Learn solid: everything that's new or changed

Next come the rewritten lines. The old version is already grooved in, so say each new line out loud from its cue until the new words come first. A rewrite you've only read silently is likely to lose to the old line under pressure.

### Hold: the long middle you already know in shape

Anything you know in sense but not word for word, plus any list or name you can't lock down in time, goes in the held pile. You'll glance at those on purpose. That's a plan, not a failure. Sam Marsden's guide to [preparing audition sides](https://www.spotlight.com/news-and-advice/the-essentials/audition-sides-and-how-to-prepare-them/) puts it simply: if you're likely to forget lines, you're usually better off keeping hold of the sides.

## Learn the new lines by meaning, then by testing

Rereading new pages twenty times feels like work, but it isn't the fast route. The psychologists Helga and Tony Noice spent nearly two decades studying how actors learn roles. As the [APS Observer summarizes their work](https://www.psychologicalscience.org/observer/to-be-or-or-um-line), actors often don't consciously try to memorize the words. They break the script into logically connected beats or intentions and learn what each line is doing. The words follow the meaning.

So for each new or changed line, write in the margin what it's trying to do to the other person: warn, flatter, stall, confess. Once you know why a line exists, it has somewhere to live.

One of their findings is useful tonight: lines learned while making an appropriate movement, such as walking across a stage, were remembered better later, even without repeating the movement. Stand up and walk the new lines.

Then test yourself instead of rereading. Cover your line, say it from the cue, check, and fix. Our [free first-letter memorizer](https://www.offbook.com/tools/first-letter-memorizer) turns any speech into first-letter cues, a good middle step. For more on the mechanics, our guide to [an audition tomorrow when you don't know the lines](https://www.offbook.com/blog/last-minute-audition-tomorrow) has an overnight plan.

One warning from Jessica Hartley, who leads the MA/MFA Actor Training and Coaching course at the Royal Central School of Speech and Drama, quoted in Sam Marsden's guide to preparing sides: "don't learn intonation or rhythm, don't set them." Cramming tempts you to lock each line to one safe reading. Marsden's guide notes the panel is watching how well you take direction, and a line glued to one tune is hard to redirect.

## Not every word has to be perfect

Shakespeare wrote this exact panic into *A Midsummer Night's Dream*. Quince is handing out parts for the workers' play, and Snug, cast as the lion, is worried before he's seen a page:

> **SNUG:** Have you the lion's part written? Pray you, if it be, give it me, for I am slow of study.
>
> **QUINCE:** You may do it extempore, for it is nothing but roaring.

*Source: William Shakespeare, A Midsummer Night's Dream, Act 1, Scene 2 (public domain; Project Gutenberg text).*

Quince then asks everyone to *con them by tomorrow night*, which is your deadline too. Snug fears the job is the words. Quince's answer is cheeky, but right: some moments just need you to know what you're doing in them. That's what keeps a glance at the page from turning into a stop. The full scene is in our [Midsummer Night's Dream](https://www.offbook.com/plays/a-midsummer-nights-dream) page if you want to run it as practice.

## Hold the pages like you meant to

Holding sides is normal in many rooms. In an [older post on being off book](https://www.marciliroff.com/to-beoff-book-or-not-to-beoff-book-that-is-the-question-4-hot-tips-for-success/), Liroff says to hold the sides in front of you and turn the pages with the flow of the scene. She adds that holding them reminds the network and studio executives watching outside the room that the audition is a work in progress. She also warns that an actor who is always looking down breaks the spell.

So make the glances count. When people read aloud, the eyes run only a little ahead of the voice: a classic estimate for college students is about two to three words, and the researchers Jochen Laubrock and Reinhold Kliegl note in their [study of reading aloud](https://pmc.ncbi.nlm.nih.gov/articles/PMC4585246/) that readers "don't want the eyes to go too far ahead of the voice." You can't read a whole line while looking at your partner.

The fix is to separate looking from speaking. Glance down during your partner's line or on a natural pause, take the phrase in, then look up and say it to them. Keep your thumb on the margin next to where you are. Our guide to [cold reading](https://www.offbook.com/blog/how-to-cold-read-for-auditions) has drills for this, and they work just as well for half-learned pages.

## Say nothing, or say one plain sentence

This is where actors often hurt themselves. You walk in and say, "Sorry, I only got these last night, so I'm not really off book." You meant it as context. It plays as an excuse, and lowers the bar before you've started. Liroff's advice in her post on audition mistakes is blunt: "Stop talking us out of liking your performance."

Casting sent the revision, so they already know it's new. Often the best thing to say about the new pages is nothing. Hold them well and play the scene.

If you're asked, keep it to one neutral fact with no apology attached: "I have the revised pages from last night." Then stop talking and start the scene. If you don't have the new version at all, say so plainly before you begin.

If the read goes off the rails, the same rule applies. From the same post: "No excuses, no apologies." Say "I'm going to start over," and do it. Our guide on [what to do if you mess up a line in an audition](https://www.offbook.com/blog/messed-up-line-in-audition) covers when to push on and when to restart.

## When the change is to a self-tape

On productions under SAG-AFTRA's 2023 TV/Theatrical Agreement, self-tapes come with some protections. Under those changes, as the union's indie arm [SAGindie summarizes them](https://www.sagindie.org/sagaftra/contract-changes-2023/), sides are supposed to reach actors at least 48 hours before a self-tape is due (72 hours for minors). The same summary limits a first self-tape to 8 pages and says an actor can't be required to memorize sides.

The summary doesn't say whether a revised set of sides restarts that 48-hour clock. If revisions land so late that you can't do the work, ask your agent or manager to request more time instead of guessing. It's a normal request. Casting director Ramani Leah writes on [The Casting Director's Cut](https://www.thecastingdirectorscut.com/did-you-know-self-tape-extensions-can-sometimes-be-a-cause-for-concern-and-stress-for/) that the biggest reason her office extends a deadline is simply that a lot of reps ask for it.

Whatever you send, check the scene heading and last line against the newest pages before you tape.

## A plan for the night the pages change

1. Read the new pages once, for the story. Don't learn anything yet.
2. Compare old and new with a pen and mark every change by kind.
3. If the given circumstances changed, rework them first.
4. Learn your first line, your last line, and the turn until you can say them looking at a wall.
5. Say every rewritten line out loud from its cue until the new words come before the old ones.
6. Learn the new material by meaning, on your feet, by testing.
7. Run the whole scene with the pages in hand, practicing the glance on your partner's lines.
8. Print the new version, mark it lightly, leave the old one at home, and go to sleep.

Step seven is the easiest one to skip. Liroff writes that you can't get a natural conversational rhythm without practicing with another person, and late at night there's often nobody to call. Offbook helps here. Photograph the new pages on your phone or paste the text from the email, pick your role, and realistic voices read every other part, waiting for you to finish your line before they cue the next one. Hide your own lines while everyone else's stay on screen to test the cold and solid piles, then run it with the pages showing to practice the glance.

## Get faster before the next rewrite

Actors who handle new pages calmly have usually just done it more. Liroff's suggestion is to learn a scene every day, even when you don't have an audition coming up, so learning fast becomes a habit rather than an emergency.

Pull a short scene from our [plays library](https://www.offbook.com/plays) or a speech from the [monologues collection](https://www.offbook.com/monologues) and give yourself twenty minutes. Then change three lines yourself and learn the new version. It's exactly what a revised side tests.

The next 9:40 email will still be annoying. It just won't be a crisis.

## Questions actors ask

### What if the sides change the night before an audition?

Compare the new pages with the old and sort the changes: cuts, small rewrites, new material, or a new situation. Keep the work that still applies. Learn your first line, last line, and the turn of the scene, then the changed lines, and plan to hold the rest. Everyone else got the same pages on the same clock.

### Can I hold my sides in an audition?

Often, yes, and with brand-new pages it's the sensible choice. Preferences vary by casting office, so follow any instructions you're given. Hold them in front of you, turn the pages with the scene, and glance down on your partner's lines rather than mid-sentence.

### How do I learn new sides fast?

Learn what each line is trying to do before the words, say lines out loud from their cues, move while you work, and test instead of rereading. Do your first and last lines and the changed lines first. A scene partner, real or Offbook's voices, shows you which lines are actually there.

### Should I tell casting I got the new sides late?

Usually not; they sent them. If it comes up, give one neutral sentence with no apology and start. Flag it up front only if you don't have the current version at all.
