Give your partner something they can use.
Life and work
Keith Johnstone (1933–2023) was a theatre teacher, writer and director whose improvisational work developed through the Royal Court, the Theatre Machine and later work in Canada. You can follow the early teaching in his publisher biography and the later history in his official record.
Where you find the work taking shape
You can follow Johnstone from the Royal Court Theatre into the Theatre Machine, founded in England in 1967, and then into a sustained Canadian teaching and theatre practice. His official history records cofounding the Loose Moose Theatre Company in Calgary, serving as its artistic director from 1977 to 1998, and retiring from the University of Calgary as professor emeritus in 1995. You are encountering ideas developed across professional theatre, teaching, and improvised performance before public audiences.
You also find a distinction between the books and the organized performance formats. In Impro and Impro for Storytellers, you meet accounts of the work. In Theatresports, Maestro Impro, Gorilla Theatre, and The Life Game, you encounter distinct formats with their own histories and arrangements. You can study the underlying questions without claiming that a short scene invented in your rehearsal room is one of those formats.
How you recognize status in behavior
What happens when you wait for someone else to finish? What happens when you assume that the next turn belongs to you? You can observe status as a relationship being made through behavior. You do not have to translate a character's profession into a fixed level of authority. In your own scene, a person with a grand title may spend the entire exchange seeking reassurance. A visitor may quietly determine what happens next.
You can also notice the pressure to be original. If you reject your first useful response because it seems too obvious, your partner may be left without anything to receive. Try to contribute something that belongs to the shared situation. You can discover what is surprising after the offer has been made. The rehearsal question is whether your choice helps an event develop.
Read Johnstone with curiosity about the conditions under which play becomes possible. Your preparation can include attentiveness, familiarity with the form, and willingness to revise an offer. Spontaneity does not mean that you have no craft. It means that your craft remains available to something you did not fully plan.
Approach and technique
Johnstone’s Impro brings together status, spontaneity, narrative skills, and masks and trance. The first three offer useful starting questions: how are people positioning themselves toward one another, what can you accept in the moment, and how does an event lead to the next?
Status gives you a way to observe a relationship through behavior. Who waits for an answer? Who interrupts? Who makes room? You can investigate those actions without equating status with a person’s worth or assuming that a job title determines every exchange. Spontaneity and storytelling then ask you to make a usable contribution and let the partner’s response matter.
Applications for actors
You take responsive play into improvisation and scene work. Offer something clear enough for another actor to build on. Notice when the need to be clever pulls your attention away from the shared situation.
Rehearsal exercise
With a partner, invent a scene about choosing where to rehearse. In the first version, one person makes a suggestion and the other receives it before adding a practical detail. Continue until you have a place and a reason to go there. Keep the scene brief.
Repeat with the same goal, changing who takes more time before answering and who rushes to fill a silence. Ask what changed in the relationship and whether a story began to emerge.
Try one more version in which a practical obstacle appears: the chosen room is unavailable. Receive that fact and build the next step together. Notice whether either person keeps returning to the abandoned plan or can use the new information. Ask a watcher to describe the sequence of events in a sentence. If the story is difficult to follow, make the next offer more concrete. Shared invention grows from contributions that give the other actor an action, a relationship or a situation to develop.
Books and further study
Read Impro: Improvisation and the Theatre for Johnstone’s account of his teaching, and consult his official site for Impro for Storytellers and the history of the performance formats. Begin with a clearly defined exercise and its purpose; different parts of his work ask for different preparation.
