Actor's Nightmare is a short-form scene game in which one performer reads scripted dialogue verbatim from a play or text while their partner improvises responses to justify those lines and sustain a coherent scene. The challenge for the improviser is to receive fixed, often unexpected lines and make them land within a believable dramatic reality.
Structure
Setup
Two performers take the stage. One receives a script: typically a few pages from a public-domain play, a scene excerpt, or printed text. The other performer has no text.
Progression
The scripted performer delivers their lines in order, as written, with full commitment and intention. The unscripted performer improvises everything else: responses, physicality, character, location, and relationship. Each scripted line arrives as a new offer; the improviser must accept the given circumstances and keep the scene moving forward.
The scripted performer can voice one character or pick between characters, selecting whichever choice gives the scene the most useful material. Minor adjustments, such as removing confusing pronouns, are permitted. The scripted performer should not comment on or mock the difficulty; both performers play the scene as if it were legitimate theatre.
Variations
The host can call "switch" mid-scene, at which point the improviser takes the script and the scripted performer must now improvise. A popular variation replaces a prepared script with live text messages from an audience member's phone, read as written.
Ending
The host ends the scene when the game has reached a satisfying moment or when the comedy of the dynamic is complete.
How to Teach It
How to Explain It
"One of you gets a script. Doesn't matter what it's from. You read the lines exactly as written, with full intention. You're not playing a joke: you're playing a character. The other person has nothing. Your job is to make everything your partner says make sense in the world you're creating together."
Common Notes
"Do not name the game. If the improviser stumbles, do not wink at the audience about it. Sell the scene."
"Scripted performer: read with intention. Give your partner something to work with emotionally, not just words."
Common Pitfalls
The most common failure is the improviser breaking the fourth wall to comment on the difficulty of the game. This collapses the scene's stakes immediately. Remind improvisers to stay inside the world rather than stepping outside to perform their effort.
How to Perform It
Audience Intro
"One of our performers is going to do a scene with a script. The other is completely improvising. We want to see if they can pull it off."
Cast Size
Two performers. One scripted, one unscripted.
Key Skills
Justification, listening for contextual clues, acceptance of given circumstances, scene grounding.
Wrap-Up Logic
End when the scene has a comedic peak, a satisfying dramatic beat, or when the improviser has made the scripted material fully land.
Technical Requirements
Print or display the script legibly. If using audience texts, the audience member should stay onstage for the duration.

Script Tease
Script Tease is a short-form game in which performers hold actual scripts or random text and must incorporate whatever lines they read into an improvised scene, making the pre-written words seem like natural dialogue. The game rewards the ability to justify unexpected text within a coherent dramatic context.
Alter Ego
Alter Ego is a short-form scene game in which each main character has a second performer standing directly behind them who voices the character's inner thoughts. Two players perform a scene with dialogue and action while their respective alter egos narrate the unspoken subtext: desires, fears, judgments, and contradictions that the characters would never say aloud. The contrast between what a character says publicly and what they actually think generates natural comedy and dramatic irony. The game highlights the role of subtext in scene work and rewards performers who create clear, exploitable gaps between surface behavior and true feelings. Alter Ego appears across multiple improv traditions and is documented in Andy Goldberg's Improv Comedy among other sources.
Blind Line Offers
Blind Line Offers is a scene exercise in which performers receive random written lines from slips of paper and must incorporate each one seamlessly into the scene as it unfolds. The unexpected text forces players to justify and connect disparate material in real time. The exercise trains adaptability and the skill of making any offer work.
Written Lines
Written Lines is a scene game in which performers hold slips of paper with pre-written lines that they must incorporate naturally into an improvised scene at opportune moments. The challenge lies in finding the right context to deliver each unrelated line without breaking the scene's logic. The game rewards smooth justification and the ability to steer a scene toward unexpected material.
Game-O-Matic
Game-O-Matic is a meta-improv game in which the audience suggests rules, constraints, or elements that are combined to create a brand-new game on the spot. The performers must figure out and play the invented game in real time. The game rewards adaptability and the ability to find playable structure in arbitrary constraints.
Typewriter
Typewriter is a long-form game in which one performer sits as a writer working on a book or story while the ensemble acts out the narrative being written. The author provides the narration and can edit, delete, rewind, or redirect the action at will. The game combines narrative authority with ensemble adaptability, and rewards both editorial precision from the author and immediate responsiveness from the cast.
