KEITH JOHNSTONE is one of the few internationally recognized authorities in the field of improvisation, great chunks of which he created, including improvisation forms that include Theatresports™, Maestro Impro© (or Micetro© Impro), Gorilla Theatre™, and The Life Game©. Keith has written two best selling books about his Theatre and Improvisation theories and practices, in addition to several plays and short stories.

Theatresports™ is known worldwide. The Life Game© was produced by London’s Improbable Theatre Co. (directed by Phelim McDermott). It toured Great Britain and the USA to great reviews.

His books Impro, and Impro For Storytellers, have been translated into many languages. His plays are produced world wide.

Keith’s ideas about improvisation, behaviour and performance appeal to a wide variety of groups. From Actors to Psychotherapists, Improvisation companies to Theatre Schools and Companies, Business and Management training specialists and Humanities Research Institutes, Universities and Film Production Companies have invited him to come to teach them about his ideas, and how they might apply them.

He founded the Theatre Machine Improvisation group in England in the 1960’s, touring Europe and North America , was the Co-founder and Artistic Director of The Loose Moose Theatre Company in Calgary, Canada in the 1970’s, 80’s and 90’s. He founded The International Theatresports™ Institute in 1998.

Keith Johnstone's involvement with the theatre began when George Devine and Tony Richardson, artistic directors of the Royal Court Theatre, commissioned a play from him. This was in 1956. A few years later he was himself Associate Artistic Director, working as a play-reader and director, in particular helping to run the Writers' Group. The improvisatory techniques and exercises evolved there to foster spontaneity and narrative skills were developed further in the actors' studio then in demonstrations to schools and colleges and ultimately in the founding of a company of performers, called The Theatre Machine. Divided into four sections, 'Status', 'Spontaneity', 'Narrative Skills', and 'Masks and Trance', arranged more or less in the order a group might approach them, the book sets out the specific techniques and exercises which Johnstone has himself found most useful and most stimulating. The result is both an ideas book and a fascinating exploration of the nature of spontaneous creativity.
