Understudy
Understudy is a scene game in which performers replace one another mid-scene and must instantly continue as the character just vacated, adopting their voice, physicality, and emotional state. The replacing performer must observe closely while waiting and commit to a specific replication rather than a generic impression. The game trains character observation, physical specificity, and the ability to enter mid-scene without disrupting its reality.
Structure
Setup
Three or more performers stand ready. Two begin a scene and establish their characters fully: voice, body, emotional state, relationship. A third performer watches from the side.
Gameplay
When the facilitator calls "Understudy" (or claps, or rings a bell), the performer on the side immediately replaces one of the two players. The original player steps out; the understudy steps in and continues the scene as that character, not as a new character. The understudy adopts the replaced player's voice quality, posture, energy, and status position as specifically as possible.
The scene continues without pause. The understudy's first line should follow directly from where the original player left off, maintaining the same emotional thread. There is no reset, no introduction, no pause for the new player to settle.
The facilitator may call replacements frequently (keeping the same scene alive through multiple casts) or give scenes time to develop before calling a switch. In rapid-rotation versions, the same scene runs with entirely new casts two or three times.
Variations
In the full rotation version, both players are eventually replaced so the original cast has been entirely swapped. The scene must maintain continuity of character and story through the full replacement. In the Animal Understudy variant, the game adds an animal physicality layer: each character is associated with a specific animal, and the understudy must replicate both the human character and their animal physicality.
How to Teach It
How to Explain It
"One of you is the understudy. You have been watching this scene from the wings. When you tap someone out, you step into their role and continue from that exact point, physically and emotionally. You have been watching. You know what to do."
Objectives
Understudy develops active observation and the capacity for physical specificity under pressure. Many performers observe their scene partners abstractly: aware of general emotional register but not tracking the specific physical choices that make a character distinct. This exercise makes specificity visible : the replication either works or doesn't, and the failure mode (generic character, no continuity) is immediately apparent.
Facilitating the Exercise
Before running Understudy, run a brief character-observation warm-up: have performers walk the space with a specific body part leading, then freeze and switch, noting what details they retained. This primes attention to specificity.
Call replacements often enough to build the exercise but not so often that scenes never establish. The scene needs to run long enough for a character to emerge before the understudy can meaningfully replicate it.
Common Coaching Notes
- "Watch the body, not just the words. The character lives in the body."
- "When you step in, you're already in the middle of something. Start from that."
- "If you don't know what the character does, make a specific choice and commit. Wrong is better than vague."
- "Your job while waiting is to be an expert on that character. Use the time."
How to Perform It
The Observation Window
The understudy's performance depends entirely on what they observe while waiting. Players who stand at the side watching casually and then scramble to invent a character when called have missed the exercise. The wait period is active: tracking the specific pitch of the other player's voice, the tension in their shoulders, their gestural habits, their status.
The first moment of the replacement is the most important. The understudy who enters with a specific physical choice signals mastery; the understudy who enters and then begins searching for the character signals that they were not watching.
Replication vs. Impression
The game asks for replication, not impression. Impression exaggerates and comments; replication serves the scene. The audience should sense continuity, not parody. If the scene is mid-conflict, the understudy is in that conflict from the first moment, not standing outside it making observations about how the previous player behaved.
History
Understudy as an improv game belongs to the tradition of character-transfer exercises common in actor training. The game borrows its premise from the theatrical understudy's actual job: learning another performer's specific physical and vocal choices in detail, ready to execute them without rehearsal.
No specific origin for the improv game Understudy has been documented in published improv sources. The format is related to Freeze Tag and other mid-scene replacement games in which performers enter and immediately inhabit a pre-existing character or situation. The Animal Understudy variant, documented separately, applies the same replacement mechanic to animal-physicality work.

Animal Understudy
Animal Understudy is a scene game in which performers play a scene using the physicality and vocal qualities of assigned animals while maintaining human characters and dialogue. The animal influence colors every choice without replacing the scene's content. The game produces unexpected character work and physical comedy.
Dubbing
Dubbing is a performance game in which one performer provides the physical actions for a character while a separate performer supplies that character's voice from offstage or from behind. The deliberate separation of voice and body creates inherent comedy as the two performers attempt to synchronize, producing a character that appears to have a mind of its own. Dubbing trains complementary skills: the body performer must generate clear, readable physical actions, while the voice performer must interpret and justify those movements through dialogue. The game appears across many short-form formats and is one of the most audience-accessible improv games due to its immediately visible comic mechanism.
Little Voice
Little Voice is a scene game in which one performer provides a running internal monologue for another performer's character, speaking the private thoughts aloud while the character plays the scene with a different outward presentation. The technique adds psychological depth by externalizing what the character would never say. The gap between the inner voice and the outer behavior creates comedy, dramatic irony, and character complexity. The game trains performers to play with subtext and demonstrates how much scene work depends on the difference between what characters think and what they reveal.
Henry
Henry is a short-form game in which a character with a fixed name and identity appears across multiple unrelated scenes, played by the same performer throughout. Other performers create new scenes with different premises, and the Henry character enters each scene, bringing the same personality, quirks, and behavioral patterns into wildly different contexts. The running character provides continuity across otherwise disconnected scenes. The game rewards a strong, memorable character who can fit into any scenario while remaining recognizably the same person.
Job Interview
Job Interview is a scene game in which one or more performers audition for a position while endowed with secret traits, habits, or identities that the interviewer must guess. The interview setting provides built-in status dynamics, clear stakes, and a familiar social ritual that audiences instantly recognize. The game rewards clear character physicalization, the ability to embed clues through behavior rather than exposition, and the comedy that emerges when inappropriate qualities collide with a formal setting.
Space Jump
Space Jump is a short-form game in which one performer begins a scene alone. At the call of "space jump," a new performer enters and initiates a completely different scene. When "space jump" is called again, a third performer enters with yet another scene. Eventually the scenes are unwound in reverse order, returning to each previous scene where it left off.
