Keith Johnstone" was coined by Dudeck in the 2013 biography to identify Keith Johnstone’s theories, techniques, exercises, games, terminology, and pedagogy.}} part of which are the Theatresports. He is also an educator, playwright, actor and theatre director.
Born in Devon, England, Johnstone grew up hating school, finding that it blunted his imagination and made him feel self-conscious and shy. After teaching at a working-class school in Battersea, London in the early 1950s, Johnstone was commissioned to write a play by the Royal Court Theatre in 1956. He subsequently became a play-reader, director and drama teacher there, where he chose to reverse all that his teachers had told him in an attempt to create more spontaneous actors. In the 1970s, Johnstone moved to Calgary, Alberta to teach at the University of Calgary. He is featured in the book Blink: The Power of Thinking Without Thinking by Malcolm Gladwell.
Johnstone co-founded the Loose Moose Theatre, and invented his system of training that has been influencing practice within and beyond the traditional theatre for over 50 years. His system include formats such as "Gorilla Theatre", "Micetro" or "Maestro", and "Life Game". The latter has been seen at the National Theatre courtesy of Improbable Theatre, and on U.S. cable television.
Johnstone has written two books about his system; the 1979 Impro: Improvisation and the Theatre, and the 1999 Impro For Storytellers. He is known for slogans that encapsulate his philosophy of improvisation, and include:
- "You can't learn anything without failing"
- "Please don't do your best. Trying to do your best is trying to be better than you are"
- "Go onto stage to make relationships. At least you won't be alone."
- "It's not the offer, but what you do with it."
